Deyan (デーヤン) is a member of the band Gaugastrikes and the band's bassist.
He has the appearance of a devil.
A bit frivolous. His glowing blond hair is his trademark and he loves dressing up/being fashionable. Always criticizes the members’ clothes. His aggressive performance is his strong point.
- He is based on Naoya Yoshimi, the bassist of KFK.
- Using the deyan wings that are growing from his back he can amplify the bass.
