years agos, a man and women, hakuji and koyuki, fell in love, bur unfortunately, koyuki passed away due to poisoning. then hakuji was offered the deal to become a demon. strong, trauma forgotten… it sounded like what he needed.
that’s how he became akaza, his demon form. he doesn’t know who hakuji is. but, koyuki became a demon too (izayoi), somehow. and one day, they met… akaza felt a connection, he didn’t know what it was, but it just felt…. normal. like they’d known each other before. one day, izayoi (demon koyuki) was staring at akaza with a cutesy looking face: clearly she was waiting to hear something.
akaza smiled, “you’ll always be my good girl, izayoi. you know that.”
”yes!” she mouthed wordlessly, raising up her fist as if she won something. (you can be akaza or izayoi)
