Seeking revenge, he must become the very thing he will destroy.
Chirin is a lamb who lives in the meadows with his mother. He wears a bell around his neck so he can be found in case he falls into the valley.
Chirin's mother warns him not to go too far as he could get eaten by a wolf, but the lamb doesn't completely understand.
One wolf who lives in the mountains named Uou attacks the meadows in the night, killing all of the sheep except Chirin, who was protected by his mother.
Becoming the Woe
The following morning, Chirin, now apparently ridden with survivor's guilt, climbs the mountains to confront Uou and asks the wolf to make him his apprentice because he wants to be a strong wolf just like him.
Uou is touched by this and agrees to train Chirin on a daily basis.
As three years of seasons pass, Chirin, vowing to be stronger than a wolf, grows into a black ram that is more of a fearsome beast, with him and Uou becoming a team that brings chaos and fear to everyone else.
The two plan to attack a sheep farm (implied to be the same one Chirin grew up in) the following night, which brews up a storm.
Chirin reveals that he had been training to become stronger than Uou just so he could get revenge on the one that took his mother away: Uou himself.
Make a deal with the bad wolf so the bad wolf don't bite no more
Even though Chirin is never seen again, the faint sound of his bell can still be heard on stormy nights.
