He has blue hair, and wears a T-shirt. He likes Chacha and hates Seravi. Riiya goes to the same school as Chacha. Riiya is always hungry and eats a lot.
Whenever Riiya wants to attack something, he turns into the little white wolf. Then just as he leaps towards the opponent, Chacha yells, "Wai, Riiya kawaii!" [Wow, Riiya you're so cute] and hugs Riiya.
