Joshua Kiryu

Joshua is one of the playable characters of video game, The World Ends With You. He is revealed to be the main villain all along in the end.

The Composer revealed
Near the end, Joshua is revealed to be the Composer, the leader of the Reapers. It's revealed he joined with Megumi Kitaniji, the Conductor, into forming the game all along. Joshua then returns Neku the memories of what really happened.

It turns out that he ended up running into Neku when he was looking at the painted walls. Joshua takes a shot, but it turns out he isn't trying to shoot him, but it's Sho Minamimoto. He wanted to kill him so that he can become the new Composer. It failed when Joshua, as the Composer, stops the bullets. Then he kills Neku, enabling him to become his partner in the second chapter.

The final battle
Joshua proposes the final "game" to Neku; both of them will have a revolver, and whoever survives will become the new Composer. Because of having befriended someone with characteristics like him, Neku refuses to shoot him, then he gets shot instead, keeping Joshua's position as the Composer.

However, because of his experiences with Neku, Joshua has decided to keep Shibuya the way it is.
