The Great Hero Chose To Die

Phill... no, Sven. Or was it Gerrard?
Yes. In this incarnation, his name was Kira. He gained consciousness at the age of 7, his parents were dead, he was chosen as the hero of the world, he went on a journey to acquire powerful tools and allies, he slayed the demon lord, then he was killed by an "unsuspecting" fiend hiding amongst his allies.
Unfeeling and worn out, the hero plotted, to end this tedious process. Together with a witch, he altered the events of his life and sought to die, once and for all.
But... he suddenly receives the name Belfry. He's a baby now? He failed to accomplish his goal!
Now, the great hero has to find a way to kill himself.
Permanently.
