Enji collei is the eldest - his eyes are a rosey scarlet, framed by spiky, dark brown hair. His build is lean, tall and has a strong physique. His personality is strict but loving - no nonsense type. He's smug, confident but isn't hot headed. Kasen collei is the younger of the two - his eyes are a soft lilac, hair pale grayish-white that cut short and kept neat. A little short than his brother, frame lean and agile. He's softspoken but easily angered, however he doesn't resort to physicality.
