Overview
Onigiri, also known by the Japanese title 鬼斬, is an action massively multiplayer online role-playing game developed and published by CyberStep. Its title literally refers to an oni-cutting or demon-cutting concept, matching the player character's identity as an oni, while also creating a pun on onigiri, the Japanese rice ball. The game combines Japanese mythology, fantasy adventure, anime-style character design, real-time hack-and-slash combat, role-playing progression, and online multiplayer features. The game is set in a fantastical interpretation of ancient Japan where humans, oni, gods, and other yōkai coexist. Its central narrative concerns the return of Kamikui, a destructive force that once devastated the land. In the distant past, the sun goddess Amaterasu Oomikami halted Kamikui by creating three great Seals. After one of those Seals is broken, the player character leaves the peaceful island of Onigashima and becomes involved in a journey to confront the renewed threat. The story incorporates figures and motifs drawn from Japanese legend, including Amaterasu, Susanoo, Momotarou, Yoshitsune, Shizuka Gozen, and Ibaraki Doji, while presenting them through a comedic and highly stylized anime-inspired setting. Unlike many MMORPGs that divide players among multiple races and formal classes, Onigiri makes every player character an oni. Character specialization is instead shaped by the player's selected trait and preferred weapon. The principal weapon group includes axes, odachi, spears, swords, dual swords, bows, staffs, and wands. Five traits—Power, Defensive, Kind, Daring, and Cautious—provide different weapon combinations and help define combat style. Character development also involves improving Power, Vitality, Wisdom, Mind, and Dexterity. A notable feature is the partner system. Players can travel with a group of named non-player companions, each with individual personalities and abilities. Their effectiveness and relationship with the player can be developed through an affection system, including the presentation of preferred gifts. This relationship-focused structure supplements the game's combat and exploration systems with a visual-novel-like character component. Onigiri was first released in Japan on February 6, 2014, followed by a North American release on July 1, 2014. English console editions arrived on Xbox One in October 2015 and PlayStation 4 later that month. A Nintendo Switch edition followed on January 31, 2019. The PC and console editions used separate servers while retaining broadly similar gameplay. CyberStep also expanded the property beyond the game: an anime television adaptation produced by Pierrot+ aired in Japan in 2016, and Sentai Filmworks licensed it for North America. The game received generally favorable comments for its action combat, colorful cast, and energetic presentation. Reviews also noted server latency around launch and criticized the possibility of repetitive play after players reached higher levels. CyberStep responded over time with additional high-level content, event items, and collaborations. Platform availability has changed: Xbox service ended on July 31, 2020, and the game was removed from the Xbox store. Nintendo Switch service ended on September 26, 2022. According to the cited reference material, Onigiri remained playable through PlayStation Network and Steam after those closures.
History
Onigiri was created by CyberStep as an online action role-playing game inspired by Japanese mythology and a fantasy interpretation of ancient Japan. The Japanese title, 鬼斬, can be understood as a reference to cutting or defeating oni-related demons. The name also evokes the Japanese rice ball, giving the property a playful double meaning. This wordplay is reflected in the game's tone, which combines supernatural danger with comic character interactions and exaggerated anime presentation. The setting imagines a world in which humans live alongside oni, gods, and yōkai. The backstory centers on Kamikui, a destructive entity that once left a trail of death across the land. Amaterasu Oomikami, the sun goddess, previously contained Kamikui through three great Seals. When one Seal is broken, the player character—an oni from the peaceful Western island of Onigashima—is drawn into the effort to stop the renewed threat. The story uses figures associated with Japanese folklore and history while freely adapting their personalities, relationships, and appearances for a comedic fantasy adventure. Onigiri launched in Japan on February 6, 2014. CyberStep subsequently brought the game to North America on July 1, 2014. The title was designed as a cross-platform online game, although its PC, Xbox One, Nintendo Switch, and PlayStation 4 versions operated on separate servers. English-language console releases followed in October 2015: the Xbox One version on October 2 and the PlayStation 4 version on October 6. The Nintendo Switch edition was released on January 31, 2019. The game's core design differs from the class-and-race structure common in MMORPGs. Players control oni characters and select a preferred trait rather than choosing from a conventional set of races or classes. Traits determine access to combinations of weapons such as swords, axes, odachi, spears, bows, dual swords, staffs, and wands. Progression includes five basic attributes—Power, Vitality, Wisdom, Mind, and Dexterity. Combat is real-time and action-oriented, with dungeon and exploration activities designed around weapon use and character development. The partner system became one of the game's defining character features. Players can recruit and travel with named companions who have distinct personalities, abilities, and dialogue. Affection can be increased through gifts, allowing the companion relationships to develop alongside ordinary combat progression. The cast includes Shizuka Gozen, Yoshitsune, Ibaraki Doji, Kaguya, and Amaterasu, with additional characters such as Veronica, Uzume, Kijimuna, Sakura, and Jin contributing to the broader story. CyberStep expanded the property into animation in 2016. The Onigiri television series was produced by Pierrot+ and broadcast in Japan from April 7 through June 30, 2016. Sentai Filmworks licensed the series for North America. The adaptation used the game's principal characters and setting while presenting them in a shorter television format with a strong comedic and ensemble focus. Critical reception was mixed but generally positive. Reviewers praised the combat, character personality, and accessible hack-and-slash structure. Some launch criticism focused on server-side latency, while later commentary questioned the repetitive nature of progression after players reached higher levels. The developers attempted to extend the endgame through additional high-level content, event-exclusive items, and collaborations with other intellectual properties. Reference material also records a level-cap expansion on the English PC server to level 135 in the late 2010s. The availability of Onigiri has varied by platform. Xbox servers were closed on July 31, 2020, and the title was removed from the Xbox store. Nintendo Switch servers were closed on September 26, 2022. The cited material states that the game continued to be playable through PlayStation Network and Steam after those platform closures. Because the available reference does not provide a current corporate profile, ownership details beyond CyberStep's developer and publisher role, or a complete present-day service statement, those fields remain limited.
