His black hair, sometimes depicted with a blue tint in official illustrations, is styled high at the back of his head like a "chonmage."

Aki's effectiveness as a Devil Hunter largely depended on his contracts with various devils, each granting him unique, albeit costly, powers:
- Fox Devil: His initial contract allowed him to summon the Fox Devil's head to devour enemies, requiring skin or hair as a sacrifice. This particular Fox Devil was superficial, preferring "good-looking" contractors, and Aki lost access to it after displeasing it during the fight with Samurai Sword.
- Curse Devil: Using a nail-like blade, three stabs could instantly kill a target, but at the severe cost of drastically shortening Aki's lifespan, making it a last-resort, almost unusable power.
- Future Devil: Residing in his right eye, this contract granted him the ability to see a short distance into the future. The condition for this power was unusually light, as the Future Devil simply wanted a front-row seat to Aki's impending "worst possible death," which it promised would be exceptionally horrific.
- Unnamed Devil: In a desperate bid for power to avert the "worst possible death" foretold by the Future Devil, Aki made a new, more ambiguous contract via Makima, stating he would "make any contract with any devil" for the power he craved.
