Can someone explain please? I'm confuse😭

So like they found out the blue hair guy(the one the red hair likes) is moony's contractor and he's creating monsters to attack the red hair and the purple guy was the first “monster” he created but he's just a normal human being. It’s possible the blue hair guy might remove the purple hair guy cause he isn’t attacking or being useful. We don’t know why the blue hair guy is trying to attack the red hair guy I’m confused ab that too cause doesn’t he like him?? Anyway I hope you understand! :)

Thank you so muchhh it's really help me!!

Np!
