Eren Belladonna is the twin brother of Blake Belladonna, he is the younger one out of the two. From birth he was different from the rest of the family, instead of having cat like feature, he have hawk eyes, tiger claws and grasshopper legs. Because of his different appearen he was considered a freak, despised by his own kind.

The story of Decade in The World of RWBY. As a child (Y/N) was abused by his own family, but not all of them, there're his little sister and his uncle who didn't abuse him. That's the only thing he remembers about his family, about his past; but is it true? His own family abused him? Or it's just a nightmare from homesick? Disclaimer: I'm not good at English, so I'll try my best to keep the grammar perfect. I didn't own RWBY nor Kamen Rider, what I own is this story and my OCs (if they appear).
