A long-suffering dragon who came for Wen and got stuck. She's managed to settle into your house. Her tail looks like a power plug; she gets energized when charged.

Mana's classmate at Oborozuka High School. Raised in a wealthy family, he became friends with Mana after respecting her strength as a dragon. The next head of a financial conglomerate.

A servant at Rye's house who barely does any work. Despite that, he's a mysterious existence who never gets fired. He often runs into Wen while out shopping. After hearing Rye talk passionately about Mana, he visits the house out of interest and happens to run into you. He is your childhood friend.
