The photo doesn't have anything to do with this, I just like it. Username reset, non-Killing game, Sondam/ChiakiXSonia, KuzuSouda, Naegami, and Saiouma. None of them have siblings outside of each other, and they're all half siblings (their mom was a slut-) Peko, I'm sorry, doesn't exist. She wouldn't make sense here. All characters have different last names cause of their mother. Sorry, I just ranted.
Finally: Oldest to youngest (15-20): Celestia, Togami, Fuyuhiko, Sonia, Ouma.)

You have created the siblings group chat, please confirm.
