Ragnarok Battle Offline is a beat 'em up game for Microsoft Windows created by dojin soft developer French-Bread.
The game's high sales led Gravity Corporation to give it a release outside of Japan.
Released as Ragnarok Battle, the game has been distributed in Indonesia, Taiwan, Thailand and a deluxe package in Korea which comes with its own gamepad.
[1] Though primarily a beat 'em up game, Ragnarok Battle Offline also contains some role-playing elements.
The animation became popular enough to gain the attention of Gravity, who commissioned the company to produce an actual game.
