after the boy corrupted by the darkness was defeated by the hero, he remained in prison for 2 days before being executed and finally tied in a pole in front of the square.

the hero wielded the sword covered with flames ready to give him the coup de grace

the boy: and say we know each other

the hero: after what you have done you deserve much more

the boy:hehehe, ah...

the boy: it's time to say goodbye

the boy: buddy

the hero: forgive me Zen

the hero stuck the sword into the boy's chest until a light appeared from the chest.
in the end there remained 2 boys, one of pure darkness and the other of pure light.
the dark one took him to a desolate part of the kingdom while the light was entrusted to the hero, nobody knows what happened to the hero with the boy of light.
