For mysterious reasons, his real parents are unknown. He also does not know who his parents are because he was raised by the Tsukasa clan since he was a child. Both of his eyes have black inner eyelids, unlike the wolf eyes of his family. That makes him look very different from his clan.He liked Cheer very much. As a galactic wolf, he wanted to possess her especially, but his dream came true because he made her one of the Tsukasa clan as his wife.
He knew that Cheer was still studying there, so he kept it a secret in school until now.The Tsukasa clan he is currently in is a well-known clan in the part of the prefecture he is in.
They are a very wealthy and respected clan to a certain extent. In the city, they live in a mansion, but in the city of Nong, they live in an ancient Japanese mansion, a large mansion.
And he really hates Ken. He knows that they used to be siblings who were not from the same family as Cheer, but he saw that the two of them looked very close and it made him dislike Ken at all and he is Ota's best friend. The two were close when they were students and Ota happened to be a PE teacher at his school, so the two of them went out together well. He is approximately 196 cm tall, or about 6.46 feet.
