Une autre des principales vertus de Koichi est son courage. Il est un grand fan du manga 'Pink Dark Boy' de Rohan Kishibe et veut bien visiter Disneyland Paris mais n'exprime aucun intérêt pour les 'vieux' pays comme l'Italie. Comme tout adolescent ordinaire, Koichi s'intéresse aux distractions plus accessibles. Pour cette raison, il cède facilement à la pression de ses interlocuteur et il obéit leurs demandes, comme lorque Tamami Kobayashi l'extorque sans effort, ou quand Rohan le pousse à passer du temps avec lui. etc.), et n'a aucun mal à se lier d'amitié avec autrui. Il trouve l'émerveillement dans les choses les plus bénignes et les plus banales (comme son nouveau vélo, un célèbre mangaka vivant en ville, trouver une erreur dans une carte car on peut gagner un prix. Surrounded and bloodied, Kira begins to mentally break down as Hayato informs him that these people, the spirits of Morioh, will never allow him a peaceful life.Complétant son apparence enfantine, Koichi possède également une personnalité plutôt gaie. Kira looks around desperately for an escape, only for all exits to be blocked off by curious neighbors and the fire department. Now robbed of his ace in the hole, Kira tries to flee for his life only to run into Jotaro, Rohan, and Koichi. Before it can though, Okuyasu uses The Hand to teleport Stray Cat out of Killer Queen and into his hands.

Kira, not understanding how his saving grace could be taken away so quickly and cruelly, commands Stray Cat to fire another air bomb. Josuke yells at Okuyasu while holding back tears, telling him that if he was alright, he should have woken sooner. Choosing to instead stay in Morioh, Okuyasu awoke. Okuyasu was prepared to follow Keicho into the afterlife, but Keicho told him that Okuyasu needs to follow his own path. Okuyasu tells Josuke that while unconscious, he saw the spirit of his brother, Keicho. Okuyasu happily erases the air bomb entirely while Hayato and Josuke are shocked to see he's alive. Bewildered, everyone looks over to see Okuyasu, who had survived and used The Hand to save Josuke. Before he can, however, the air bubble teleports past Josuke and misses him.

Hayato urges Josuke to use anything nearby to pop the bubble. Rejoicing that this moment is his salvation, Kira prepares to detonate the air bomb and kill Josuke.
