Himori Akiyama is a slim, young man with dark green hair and black eyes. His hair is messy and reaches down to the drape of his neck.
He wears a uniform typical of the Blue Clansmen. It consists of a white shirt tucked underneath a closed, blue overcoat with prominent black and gold-colored lining. Below the waist, he wears dark blue pants and knee-high, low-heeled black boots with metallic plates attached to the nose and end.
Himori Akiyama is quite professional in several aspects. He does not often associate himself with activities outside of his usual work within Scepter 4. While at work, he maintains a calm demeanor and often reminds his Clansmen to act in the same manner.
