Rokuta has a gentle, friendly, and innocent personality. Often compared to a puppy, he is considered a "good boy", and adorable. He underwent human experimentation for Phantommetal. Rokuta doesn't remember his past, and he can be forgetful.

Rokuta is tall, with fluffy, plae orange hair and red eyes. He wears a white side-slit white and cream jacket with a fur collar, pockets on the chest, and an orange zipper. He wears white, slightly baggy pants and white shoes with orange accents.
