Yakyuken by NAMUL is a Ren'Py adult game about playful competition, romance, and harem relationships. You play as the male protagonist, meeting multiple heroines across branching paths, with four complete chapters and a newly added Chapter 5. Matches include rock-paper-scissors, Cham Cham Cham, and cocktail mixing, and winning them unlocks special cutscenes and endings. The presentation uses animated 3DCG art, and the scenes are fully voiced, giving simple gameplay.
The current v0.4.8 build, released February 11, 2026, remains in active development. It is available on Windows, Linux, and Android in English, Japanese, and Korean, and is uncensored. The latest update adds Chapter 5, where standard rounds are replaced by story-driven special matches. It also adds a Chapter 5 gallery and a Bonus Gallery, which unlock through status or affinity in each chapter.
