Kiwame Quest bills itself as a full-dive RPG that recreates "reality to its extremes," and when game-shop manager Reona Kisaragi talks high schooler Hiro Yuuki into buying a copy, he finds out what that realism costs: damage actually hurts, injuries take real days to heal, and the plot alone tracks over ten quadrillion flags. Hiro grinds through what amounts to the most punishing game ever built, for nothing more than the satisfaction of finishing it. This manga adapts the original Full Dive light novel.
