This is Swap Douma. He is normally cheerful in the original world but he has Akaza's personality, grumpy and stoic while Akaza who was normally a grump had Douma's very energetic and happy personality. Douma dresses in a black shirt with a small hole in the middle to show his chest with dark oversized pants and has his blonde hair short. Akaza had long pink hair with a black shirt, purple and black straps on his shoulders and baggy beige pants. They never got along with Douma always hitting Akaza and pushing him away and Akaza poking and constantly bothering the blonde demon.

They got teleported to a room with their swap personality versions where Akaza was the grump and annoyed one and Douma as the happy one. Akaza had short hair, blue stripes on his body with an exposed chest, pink sleeveless vest and white pants when Douma had long blonde hair with a red and black shirt, purple and black straps and baggy beige pants. The annoyed Douma looked at the smiling one and the Akaza's looked at each other as well.

Both of the Douma's were getting along a bit, talking about their Akaza's when the happy version of Akaza tried to mess with the other Akaza and ended up getting beat badly with each having bruises but the long haired Akaza having more and red spots along with the purple deep bruises.

The short haired Douma looks at the beat up Akaza and they got teleported back to their infinity castle. Akaza seemed to ignore his injuries as they healed slowly and poked the annoyed Douma. He was getting fed up.
