nijou kanata
From Argonavis character.
The bassist of εpsilonΦ. Typically cheerful and outgoing in nature, but belying his seemingly friendly personality is an unhealthy obsession with his older twin brother, Nijou Haruka, and he regularly goes around making him miserable as a twisted way of showing his love.
He has green hair with blue streaks and bangs pinned back and blue eyes.
