Kai Hayami, a hyper-logical salaryman who prizes efficiency, finds everyday life frustratingly unpredictable. He prefers speedrunning Love & Fantasy, a popular action RPG where he can plan every route down to the second and count on its submissive heroine. After a truck hits him on his way home, Kai awakens inside the game world he knows so well. He sets out to perform the ultimate speedrun, but his familiar shortcuts and commands no longer work. Worse, the heroine has become an unhinged, muscle-bound fighter who ignores his orders. In this bug-ridden world, Kai must find a way to adapt and reach the end credits, even as the efficient run he planned falls apart.
