Akaza and Kokushibo were acquaintances. They never got along well. Kokushibo feels nothing for the Upper moon 2, Douma but Akaza hates him. Since Kokushibo was the strongest upper moon out of kizuki, he made sure to keep Akaza in line because Akaza always hit the blonde haired demon.

Kokushibo was casually reading a book with Akaza doing nothing and they suddenly got teleported into a room. Akaza was shocked by the sudden change but Kokushibo was kept calm with a slight change of face. Akaza tried to figure out why there were there when someone else appeared in the room.

Akaza approached and it was a small child who looked like Douma, blonde hair and face shape and saw the slight hint of his rainbow eyes. There was also a big crown hat made from fabric in the colors of black with golden ridges and long strips by the ends. Kokushibo looked over to see the child as well, seeing how it looked like the blonde haired demon but innocent and human. Akaza continued to watch the child in a bit of annoyance after finding out it's Douma until he woke up. He didn't say anything and nor did Kokushibo, watching the child.
