Ookami and Hitsuji: My new Characters: Ookami and Hitsuji

I've been drawing them for a long time, but now It's official.

The girl's name is Mary Hitsuji. But I don't really have a name for the wolf boy... However, it's decided that his surname is Ookami. His first name have to be a Japanese name. Do you have any ideas? Comment!!
Mary is a "sheep" person type, and ookami is a wolf type. There's no way how to exactly explain what does it means, and how without the prologue, so deal with it. They both have the same age, and they're childhood friends.

If you have noticed, I've already put some hints on Charm's about them before. For example, my profile picture, and my 2000+ likes celebration art.

I've also created a whole story about them, but it still too early to tell (^w^). Actually I won't tell because I'm thinking of creating some kind of RPG game with my older sister's help. Yep, the story is AWESOME. I'm thinking of a name for the game title
