One night the Wolf and Chirin decide to kill the sheep in the barn and that Chirin needs to kill the dogs that are guarding the barn, he kills them and breaks into the barn, he sees a mother sheep jump on her lamb to protect it as he is then reminded of his past, and he does not want to kill the sheep, the Wolf tries to kill the sheep since Chirin won't do it, Chirin than kills the Wolf and wants to live in the barn. The other sheep do not allow him to come back as he runs off to the mountains and is never seen again and everyone forgets about him, but when a huge blizzard hit, they could hear the faint sound of his ringing bell.
When he was young, Chirin was used to be a cute-looking lamb. This however, ultimately changed where after his rigorous training by Wolf King, he grew into a horrifying tall and muscular ram with long, sharp horns and demonic-looking yellow eyes.
- Chirin's backstory is similar with Simba, Bambi, and Littlefoot because they lost a parent whom they cared about, only for such similarities diverges at the point of how they would cope with it: Unlike either of them whom managed to lead the fulfilling lives, Chirin was consumed by vengeance that turned him into an abomination he unvortunately became.
- The only character whom similarities very close to Chirin was Simba, as both confront their parent's killer (Wolf King for Chirin and Scar for Simba) and the said killer eventually met their ends. However, while Chirin personally killed Wolf King, Simba chooses to banished Scar instead(though the fight between them resulting hyenas whom used to worked with Scar murdered him instead).
