lol I loved that soooo much I channeled an original character from MLP fanfic I'm reading. He got pretty angry at Discord
As for my character, I revealed a fair bit about Cyrus' girlfriend, Angel, early on but maybe, with Raindrop's permission, I can put in more. I said back when Takaya was first introduced that she looked familiar. Maybe she could be a sister? I'll ask Raindrop.
Rin and Kage is from an anime called Blue Excorcist. Chiyoko is a character I made fully. Her backstory, though, is based on Eve from Black Cat, however she has nanomachines in her body that lets her transform. I reccomend both animes, expessialy Black Cat.
