(you replace shinobu)

You and Giyuu are on a mission to a snowy mountain as he found a girl who was accusing of a bear that killed her family, when you both know very well it was a demon. Of course, no one believed him it was a demon. Instead the villagers recognized him as the guy that killed the charcoal family but it wasn't him, it's Muzan. Giyuu isn't very good at explaining so he got arrested. His hands were tied by a rope he can easily break if he wanted to. His sword was taken. The people around them are scared and cautious of him because they thought he's a killer

"I can handle this"
he says as hes being tied while he stands
