Kamisama wa Southpaw: Diamond

Kaneishi Gou never intended to step into a boxing ring, but a manipulative coach with nothing left to lose convinces him otherwise. Tricked into agreeing to a match he has absolutely no realistic chance of winning, Gou enters the world of professional fighting under a dangerously false assumption: that boxing is far easier than it appears. To ensure his compliance, the desperate coach guarantees him a payout regardless of the bout's outcome. This promise of easy money effectively strips away any lingering anxiety, allowing Gou to approach what he believes will be his first and final match with complete indifference. Freed from the pressure of needing to perform or even survive past the opening bell, Gou treats the upcoming fight as little more than a brief inconvenience on his way to a guaranteed payday. He walks toward the ring without fear, fully convinced that the arrangement protects him from any real consequences. However, his misplaced confidence and lack of preparation collide violently with reality the moment the bout begins. The illusion of an effortless paycheck shatters instantly when Gou is knocked out cold in the very first round, abruptly ending his short-lived career before it ever truly starts.
