, lit. Demon Cutter) is an action massively multiplayer online role-playing game (MMORPG) by CyberStep. It is set in a fantasy land reminiscent of ancient Japan in which humans and non-humans such as Oni and other Yōkai coexist. The game was originally released in Japan on February 6, 2014[1] and in North America on July 1, 2014. The English console versions were released on October 2, 2015[2] for the Xbox One, on October 6, 2015[3] for the PlayStation 4 and January 31, 2019 for Nintendo Switch. The game's title means "oni cutter", reflective of the player characters' background as an Oni; the title can also be taken as a pun on onigiri, the Japanese rice ball.The game is set in a fantasy version of ancient Japan that is filled with creatures of myth. Ages ago, the terrible Kamikui made a trail of death and destruction across the land before being stopped by the goddess of the Sun, Amaterasu Oomikami. The goddess placed three great Seals that forced Kamikui to retreat. Now, one of the Seals has shattered.[4]

The player character is an Oni whose peaceful life in the Western island of Onigashima is disturbed by the revival of the Kamikui.[5]The game has different servers for the PC, Xbox One, Nintendo Switch, and PS4 versions but the gameplay is the same for all versions.

Unlike most other MMORPGs, which have different races or classes, in Onigiri, players can only play as Oni and choosing a class simply requires the player to pick a favored weapon to specialize in. When creating a character, players choose one of five traits that will determine which weapons they can use. The traits are Power (Axe, Oodachi, Spear, or Sword), Defensive (Spear or Staff), Kind (Staff or Wand), Daring (Axe, Oodachi, Dual Swords, Bow, or Sword), and Cautious (Dual Swords, Bow, or Wand). Characters level up five basic stats: Power, Vitality, Wisdom, Mind, and Dexterity.[6]
