From her chocolate color! Sorry to do that to you. When I first read the announcement, I just saw the graduating part and almost crapped myself. I was like “Oh no, she just joined. How is she leaving?! etc, etc. No no, she’s just graduating from her chocolate color which I’m actually pretty sad about. I think the color really suited her. It’ll probably be purple, since Eripon is getting Niigaki’s old color of yellow-green.
