Little Busters! (リトルバスターズ!, Ritoru Basutāzu!) is a Japanese visual novel developed by Key. It was released on July 27, 2007 for Windows PCs and is rated for all ages. Little Busters! is Key's sixth game, along with other titles such as Kanon, Air, and Clannad. An adult version of the game titled Little Busters! Ecstasy was released on July 25, 2008 for Windows, unlike Kanon and Air, which were first released with adult content and then had later versions with such content removed. Ecstasy was later ported to the PlayStation 2, PlayStation Portable, PlayStation Vita, PlayStation 3, and Nintendo Switch with the adult content removed under the title Little Busters! Converted Edition. An English version for Windows was released on Steam in 2017. The story follows a group of childhood friends (Riki Naoe, Rin Natsume, Kyousuke Natsume, Masato Inohara and Kengo Miyazawa) now attending high school called the Little Busters, as they decide to form a baseball team. Riki, who is diagnosed with narcolepsy, is tasked to recruit more girls in preparation for a baseball game, and he bonds with each of them on account of their internal conflicts. Meanwhile, Rin gets mysterious letters from her cat Lennon to complete various tasks to learn the "secret to this world".

The gameplay in Little Busters! follows a branching plot line which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the six female main characters by the player character, which increases to nine in Ecstasy. There are additional minigames added into the gameplay, such as battle sequences that resemble fighting games or baseball batting practice, which serve to give the characters experience, obtain accessories to use during battle, and improve their statistics. Both Little Busters! and Ecstasy ranked as the best-selling PC game sold in Japan for the time of their release, and Ecstasy would go on to sell over 100,000 units. Key went on to produce an adult spin-off called Kud Wafter in June 2010, which expanded on the scenario of Kudryavka Noumi, one of the heroines from Little Busters! and Ecstasy.

There have been 14 manga adaptations based on Little Busters! and Ecstasy published by ASCII Media Works, Kadokawa Shoten and Ichijinsha. Comic anthologies, light novels and art books were also published, as were several music albums. There have been two Internet radio shows hosted by the voice actors of Rin and Kyousuke Natsume and Kudryavka Noumi. J.C.Staff produced two anime television series and an original video animation series between 2012 and 2014.

Little Busters! is a romance visual novel in which the player assumes the role of Riki Naoe.^[1] Much of its gameplay is spent on reading the story's narrative and dialogue. The text in the game is accompanied by character sprites, which represent who Riki is talking to, over background art. Throughout the game, the player encounters CG artwork at certain points in the story, which take the place of the background art and character sprites. When the game is completed at least once, a gallery of the viewed CGs and played background music becomes available on the game's title screen. Little Busters! follows a branching plot line with multiple endings, and depending on the decisions that the player makes during the game, the plot will progress in a specific direction.

There are seven main plot lines that the player will have the chance to experience.^[1] Throughout gameplay, the player is given multiple options to choose from, and text progression pauses at these points until a choice is made. To view all plot lines in their entirety, the player will have to replay the game multiple times and make different choices to further the plot to an alternate direction. When first playing the game, the scenarios for all six heroines are available. Once a scenario for any one heroine is completed, that scenario will be unavailable in the next play through because the last choice that will ultimately lead to that heroine's scenario becomes unavailable for players to choose. After the completion of these six routes, the final scenario called Refrain is made available, which serves to bring everything to a definite conclusion and answers questions brought up throughout the normal gameplay. Completing Refrain makes available all the heroine's scenarios that were previously made inaccessible during gameplay so that the player can revisit the scenarios again, along with some extra decision points that were previously unavailable.

Throughout gameplay, the player encounters various minigames, which range from simple to more complex. The first type of minigame encountered is a battle sequence that resembles a fighting game, but no interaction from the player is required to fight.^[1] These recurring battle sequences represent when the members of the Little Busters get into physical fights with either each other or with others. Each member of the fight has a set of statistics attributed to them (which includes strength, stamina, agility, reflex, concentration, judgment, and luck) along with a life bar to keep track of how many hit points a fighter has left. The maximum number of hit points is determined by the given fighter's stamina rating. Weapons may be used along with any accessories the fighter has in their possession, and these items may be exchanged with other characters.^[1] Another recurring minigame involves the player being able to play baseball batting practice with members of the Little Busters. The player, as Riki, controls his position and when to swing the bat.^[1]

The Little Busters will also participate in missions to accomplish some goal, and a mission will either be completed or failed depending on the choices of the player. These missions are connected with the battle sequences and batting practice in that they serve to give the characters experience, obtain accessories to use during fights, and improve their statistics.^[1] However, these missions do not affect the main plot in any way—the player even has the choice to turn off most of the minigames so that the player may focus on the main plot, including the battle sequences and batting practice. The first time that the game is played, Rin's statistics are weak compared to other characters. However, when the player completes several heroine's routes, Rin's and Riki's statistics will start out higher than before when the player starts a new game, allowing Rin and Riki to stand a better chance against opponents with higher statistics.^[1] The statistics of the Little Busters members are shown in a ranking system from highest to lowest in overall statistics.

Despite Little Busters! having a rating for all ages, there is an ample amount of CG artwork featuring the female characters in risqué situations, though never to the point to be considered sexual in nature.^[1] This is in stark contrast to Key's previous titles Clannad and Planetarian: The Reverie of a Little Planet that also have ratings for all ages, but those titles contain no such risqué situations or even any fan service.^[2][3]

In Little Busters! Ecstasy, adult elements were added to the gameplay in the form of sexual CGs depicting Riki and a given heroine having sex. Ecstasy extends the story for the scenarios of the heroines in Little Busters!, as well as increasing the number of heroine routes from six to nine. These three heroine routes include scenarios for Kanata Futaki and Sasami Sasasegawa—two supporting characters from Little Busters!—and a new heroine named Saya Tokido who is only featured in Ecstasy. The first time the game is played, these three heroine routes are unavailable to the player until after the Refrain scenario is completed, though the player is given the option to make them immediately available. Ecstasy has several minor additions and changes to the minigames as well, including the addition of weapons available for use in the battle sequences.^[4] Also, Ecstasy features the addition of two recurring minigames related to Saya: a shooting game with pistols and navigating a labyrinth.

The main part of the story takes place at a high school in Japan. There is a "secret of this world" that Kyousuke speaks of; Kengo and Masato are also aware of this.^[5] The characters live in either the male or female dormitories on the school grounds which are across from each other. Beside the dorms is the main school building where classes take place, which also houses the cafeteria on the ground floor. The school is four stories and the roof is normally restricted from access. Beyond the main school building is the large schoolyard, with the pool area adjacent to the yard. On the other side of the field is the baseball field, with the gymnasium and tennis court beyond it, which are closer to the main school building.

Childhood and adolescence are two important themes in Little Busters!.^[6][7] The opening video of the visual novel starts with two lines written in English: "What 'Adolescence' do you have?" and "Do you remember 'Childhood'?". Riki Naoe, the male protagonist, has four childhood friends with whom he grew up together through adolescence and still hangs out with when the story begins. Thus, friendship^[6][7] is another theme presented in the form of Riki's relationships with his friends in high school, and is thought to be irreplaceable. The opening video of the original visual novel contains a third line written in English, "The irreplaceable one existed there," though another line was added into the opening video of Little Busters! Ecstasy: "This will remind you that you have to recollect 'Adolescence'."

The player assumes the role of Riki Naoe, the protagonist of Little Busters!. He is seen as weak due to his girlish appearance and physical build but is very straightforward and has more common sense than most of his friends. He is a member of a group of friends called the Little Busters, which originally consisted of four members, but expanded to five with Riki during his childhood. The leader of the Little Busters is Kyousuke Natsume, who is the eldest member. He often comes up with absurd ideas, but almost always follows up with a reasonable explanation along with it.

Kyousuke's younger sister is Rin Natsume, the main heroine of Little Busters!, and is initially the only female member of the Little Busters. She does not communicate well with others due to her poor social skills and can be seen as inarticulate. Due to this, she is shy, and is usually seen alone. Rin loves cats and at school takes care of several strays. Riki's roommate and fellow member of the Little Busters is Masato Inohara who loves to work out and improve his muscle mass. He has a particular fondness for Riki, which he is more than willing to express out aloud. Masato's rival and fellow member of the Little Busters is Kengo Miyazawa who is skilled in the art of kendo and seemingly has a cynical personality, but his passion for the Little Busters is unmatched by any of the other members.

In Little Busters!, Riki meets five other girls attending his high school who later become members of the Little Busters, in addition to three more girls in Ecstasy; all eight are heroines in the game. The first is Komari Kamikita, a childish girl who takes great interest in fairy-tales, picture books, candy, and clothing with many layers of frills. She is very clumsy, though athletic, and will often not think before she acts. Haruka Saigusa is a schoolmate of Riki's from a different class, but always finds time to hang around in Riki's classroom. She incites uproars for her own personal enjoyment, which causes her twin sister, the public morals chairman Kanata Futaki, to chase after her. Kanata generally acts cold towards her sister, though gets annoyed when Riki gets close to Haruka. Kudryavka Noumi, known as "Kud" (クド, Kudo) for short, is a girl who is one quarter Japanese, and three-quarters Russian. Despite having a poor handle on the English language, she was able to skip a year in school due to credits obtained through studying abroad, making her the youngest member of the Little Busters. Kudryavka appears in Key's eighth game, Kud Wafter, as the main heroine.

Yuiko Kurugaya is Riki's classmate who has a self-sufficient personality, and is sometimes seen carrying a replica of a katana called Muramasa. She is seen as an older sister to everyone despite being the same age of almost the entire cast, and is fond of things or people she considers to be cute.^[8] Mio Nishizono is a calm girl who is very diligent. Due to having weak health, she is always seen with a parasol when outside. She enjoys reading, especially when the story contains boys love elements, and her room is filled with books. Sasami Sasasegawa is the captain of the girls' softball team and is Rin's rival; while Rin loves cats, Sasami is a devoted dog lover. Saya Tokido, who only appeared in Ecstasy, is a popular girl at Riki's school, though she is known to be ditzy. At night, she wanders around the school to protect a "treasure" from those she calls the "darkness executives" (闇の執行部, yami no shikkōbu), and even has to fight them for it.

Little Busters!' story revolves around the main protagonist Riki Naoe, a young male high school student. When Riki was a child, his parents died, leaving him hopeless and depressed. He was saved by a group—three boys and a girl, all his age—who referred to themselves as the Little Busters, a group dedicated to fighting evil and preserving justice.^[9] The leader of the group was Kyousuke Natsume who had a younger sister named Rin. The other two members were Masato Inohara and Kengo Miyazawa, who were friends despite being rivals. They took Riki out and played together with him during his time of need, making him the fifth Little Busters member. In time, Riki enjoyed playing with them, and his grief over his parents gradually faded away.^[9] When the story begins, Riki and his friends are seemingly in their second year of high school, except for Kyousuke who is in his third year. They still hang out together, and enjoy their school life.

The story opens on Sunday May 13, 2007, and the next day at school, Kyousuke decides that the Little Busters are going to play a baseball game, except they do not have enough members to have a complete team. Kyousuke gives Riki and Rin the task of going around school to find more members to join, preferably girls so as not to leave Rin the lone girl. Riki finds five girls his age willing to help him out: Komari Kamikita, Haruka Saigusa, Kudryavka Noumi, Yuiko Kurugaya, and Mio Nishizono; three other girls Riki meets are Kanata Futaki, Sasami Sasasegawa, and Saya Tokido. Throughout the game, Riki hangs out with these girls and learns more about them.

The story's main part takes place in what seems to be a normal high school, but in fact all took place in the school term previous to Little Busters!, and Riki and Rin are reliving it in an artificial world created by the other members of the Little Busters. They, and the other main characters, were involved in a bus accident during a field trip, and only Riki and Rin will survive. Kyousuke and the others created the artificial world to make them strong enough to deal with what will happen when they awaken in the real world. This was caused by a ripple effect based on all of their desires to save Riki and Rin. The world loops, but though they forget what happens, Riki and Rin do grow stronger, and Kyousuke hopes that they will eventually be strong enough to leave the artificial world. They do manage to survive and get away from the crash site before Riki collapses because he has narcolepsy. Riki vows to fight against his narcoleptic condition, which was the reason why he was only able to save Rin and merely get away from the explosion before collapsing.

Rejecting this turn of events, Rin travels back into the artificial world again (this time created by Riki and Rin) and helps Riki overcome his weakness. Afterwards, the two of them go back to waking up at the crash site. This time, Riki and Rin work together to save everyone at the crash scene. Kyousuke, who sneaked onto the bus (as a third year he was not allowed to go), managed to block the leak hole on the gas tank to delay the explosion, despite his injuries being far greater than anyone else. Everyone in the bus recovers from their injuries, although Kyousuke's recovery takes longer due to extensive injuries. Finally, after Kyousuke returns, he rents a minibus, and the members of the Little Busters set out for a trip to the ocean.

For the first time in Key's history, two artists were given the position of art director for the visual novel: Itaru Hinoue and Na-Ga.^[10] Hinoue has been Key's signature art director since Key's first game Kanon, and Na-Ga has been with Key since the production of Air working as one of the computer graphics artists to render background art used in Key's games. Due to having two art directors, character design was split between the two, though Na-Ga is responsible for the character design of the majority of the cast. Of the six heroines in the story, three were designed by each artist; Komari, Haruka, and Yuiko were designed by Hinoue while Rin, Kudryavka, and Mio were done by Na-Ga.

For work on the scenario, Jun Maeda contributed along with composing some of the game's music.^[10] Further writers include Leo Kashida who had worked on Tomoyo After: It's a Wonderful Life, and two new scenario writers to Key—Yūto Tonokawa, and Chika Shirokiri. Maeda wrote the scenarios for Rin and the entire male cast; Kashida wrote the scenario for Mio; Tonokawa wrote the scenarios for Komari and Yuiko; finally, Shirokiri wrote the scenarios for Haruka and Kudryavka.^[11] In an interview of Maeda and Tonokawa in the August 2007 issue of Push!!, it was reported that the story of Little Busters! is twice as long as Air's, but only half as long as Clannad's. However, this does not take into account the minigames in Little Busters! which serve to lengthen the game.^[12] The music in the game, not counting Maeda's, was composed by Key's signature composers Shinji Orito and Magome Togoshi, in addition to Manack and members of PMMK.^[10] Togoshi left Key in October 2006 before the visual novel went on sale.^[13]

Three or four months before the release of Little Busters!, it was decided that an adult version of the game would be developed titled Little Busters! Ecstasy (リトルバスターズ!エクスタシー, Ritoru Basutāzu Ekusutashī), or Little Busters-EX for short.^[14] Na-Ga designed the heroine Saya Tokido and Maeda wrote her scenario. Tonokawa wrote Sasami Sasasegawa's scenario, and Shirokiri wrote Kanata Futaki's story. Lines from the original game were rewritten as well for Ecstasy, and the total number of lines with spoken dialogue comes to 43,347 lines.^[15][16] The total word count in Ecstasy exceeds that of Clannad by about 4,000 words, making it Key's longest work, and carries so much data that Ecstasy was released on two DVDs instead of one for the original release.^[17][18]

An art exhibition of Little Busters! was held in Osaka, Japan between May 3 and May 4, 2007,^[19] and in Tokyo, Japan between May 24 and May 25, 2007.^[20] A large amount of the character and background art featured in the game was showcased, along with original art used to promote the character artwork, and other production sketches drawn when the game was still in development. Flowcharts outlining the story for the game were on display, along with the flowcharts for Clannad.^[21] Also at the exhibition was a life-size mannequin of Rin Natsume with a baseball glove in one hand, though instead of a baseball, a cat was in the glove.^[20] This mannequin was later put onto the Japanese Yahoo! Auction website in late September 2007 and sold for 764,000 yen,^[22] a far cry from the original wish of selling the figure for 5,000,000 yen.^[22]

Little Busters! was the first Key title to receive coverage in an entire issue of Dengeki G's Festival!, a special edition version of Dengeki G's Magazine which is published in irregular intervals each year by ASCII Media Works; the issue in question was the ninth, published on June 30, 2007. Along with a full 80 pages of information on Little Busters!, the magazine came bundled with a double-sided hug pillowcase, a small cell phone cleaner which could also attach to a cell phone, and a B5 size jigsaw puzzle.^[11] ASCII Media Works published the third volume of another special edition version of Dengeki G's Magazine named Dengeki G's Festival! Deluxe on June 30, 2008 which had a focus on Little Busters! Ecstasy. Along with again containing about eighty pages of information pertaining to the visual novel, the magazine also comes bundled with an ergonomic mousepad, a jigsaw puzzle, and a deck of playing cards.^[23] The third volume of another magazine in the Festival! line, Dengeki G's Festival! Comic, was sold on July 26, 2008 with Rin and Dorj on the cover, and the magazine came bundled with a hug pillowcase, a notepad, and a B2 size poster.^[24]

On June 1, 2007, a free game demo of Little Busters! became available for download at Key's official website. In the demo, the player is introduced to the characters of the Little Busters group in the game through a short visual novel sequence. The demo does not give the player the chance to interact with the scene presented, making the demo a short kinetic novel. The game was released in Japan as a limited edition version on July 27, 2007 as a DVD playable on Windows PCs;^[7][10] the regular edition was released on September 28, 2007.^[25] The limited edition contained an arrange album of some of the music featured in the game, and a 128-page visual guide book titled Natsume Kyousuke Fūrai Ki (棗恭介風来記).^[10] The book contained information and images on characters, background CGs, the art exhibition, images of the heroines published in various Japanese anime and gaming magazines, a question and answer section, information on the creators of the game, and lyrics of a couple of songs featured in the game.

Little Busters! Ecstasy was released as a limited edition version on July 25, 2008 as two DVDs playable only on a Windows PC;^[17] the regular edition followed on September 26, 2008.^[26] The limited edition came bundled with a remix album of music featured in the game, and a 22-minute length CD containing a special broadcast of the Little Busters! Internet radio show. An updated version, 1.01, for the limited edition of Ecstasy was released by Key for free on their website on September 22, 2008; the regular edition of Ecstasy contains this update.^[27][28] An all ages version of Ecstasy for Windows was released by Key on July 31, 2009 in a box set containing five other Key visual novels called Key 10th Memorial Box.^[29]

Converted Edition, also by Prototype, was released on November 25, 2010.^[33] The Windows and PS2 versions had voice acting for only the major characters, but the PSP version contained full voice acting for all of the characters other than Riki.^[33] Prototype also released a version of Little Busters! Converted Edition ported to the PlayStation Vita (PS Vita) on March 22, 2012.^[34][35] Along with also having full voice acting, the PS Vita version contains 1.4x larger CGs than the Windows edition, and the limited edition came bundled with a drama CD.^[35] Prototype released a PlayStation 3 (PS3) version of Converted Edition with the additional content included in the previous consumer ports on March 20, 2013.^[36][37] An added feature in the PS3 version is a 3D rendering of the minigame in Saya's route where the player must navigate a labyrinth.^[38] A downloadable version of the PS3 release via the PlayStation Store was released by Prototype on May 29, 2013.^[39]
