Koi-Koi

Four illustrated Koi-Koi worlds, 19 stages: ukiyo-e rivals, surreal cafés, a midnight commute, and a live broadcast layer.

Koi-Koi is a cinematic hanafuda card game built around four distinctive worlds. Begin with Nitō the Ronin at Red Fuji for free, then unlock premium campaigns and modes when you are ready.

Play Hokusai Battles across a seven-rival ukiyo-e journey, step into the warm chaos of six living cafés, ride an after-work night toward the last train, or add Talk Show + Cross Mode for live commentator reactions across supported worlds.

The game preserves traditional Koi-Koi tactics while presenting each match as a richly illustrated scene with authored rivals, stages, music, and atmosphere.
