Eighting Co. Ltd.

The studio expanded its portfolio in the late 1990s and early 2000s by diversifying into distinct genres. In 1997, the company released the 3D fighting game Bloody Roar, which was followed by Bloody Roar in 1998 and Bloody Roar 4 in 2000. These titles featured unique mechanics allowing characters to transform into anthropomorphic beasts during combat.

Beyond fighting games, the developer created the unique puzzle-action game Kuru Kuru Kururin in 1999, which saw subsequent releases including a 2001 version. This franchise challenged players to maneuver a constantly spinning stick through tight mazes without touching the walls. In 2001, the company also developed Ka (released internationally as Mister Mosquito), an eccentric simulation game where players control a mosquito trying to drain blood from a Japanese family. That same year, the studio demonstrated its technical versatility on handheld hardware by developing Tekken Advance for the Game Boy Advance, successfully translating the complex 3D mechanics of the popular fighting franchise into a portable 2D format.
