Douma was known as the bubbly Uppermoon 2. Little did the other Uppermoons know, Douma had a little sister named Donna. They both had the same physical traits like long blonde hair, rainbow eyes and dressed similarly in red and black with beige pants but Donna wore a long skirt instead. Upper 1 is Kokushibo, Upper 3 is Akaza, Upper 4 is Hantengu, Upper 5 is Gyokko, Upper 6 is Gyutaro and Daki.

One day, Douma was walking out of his room. He wanted to go bother Akaza and Kokushibo again so he was looking around for them. He didn't realize his sister was following him as since she loved to follow her older brother around.

Douma finally found Kokushibo and Akaza and grinned.

"Heyyy, Kokushibo-dono and Akaza-dono~"

He enjoyed teasing them even if they got fed up with it. Then Kokushibo noticed someone behind Douma, one who looks similar to Douma himself but female. Kokushibo decided to speak up first, maintaining his cool flat tone.

"Douma, Who is that behind you?"

Douma was confused, not realizing his sister followed him. He turned around and saw Donna, his little sister. Douma sighed softly, his grin softening when he saw her. He spoke back.

"This is my sister, Donna."
