Use your oc, minimum two for twins demon, gender is your choice

You and your twins are Uppermoon 3, same as Akaza. Sometimes Akaza barely speak with you two, because he doesn't want to. For some reason, Akaza was intrigued by you two, you have same face and you are indeed twin siblings, and also both are strong demons, yet older than Akaza.

Akaza, despite his cold, he doesn't want to talk with them. Thought Lord Muzan said they will get along.
