Appearance
Akachi has short black hair and red colored eyes.

Personality
Akachi doesn't show emotions until he becomes angered, then he lashes out. Akachi has a chip on his shoulder from being a slave before turning into a Shinshou, his main goal is to be treated an equal by Kannagi who was his master. Akachi had a younger half-sister, Emisu, who he treasured for being his last living family member. Her death causes him to grow hatred towards Kannagi. Akachi stays calm and doesn't allow others to read him, he prefers to keep others at arms reach. He relates to Kadowaki's feelings of not wanting to be overshadowed and therefore gives his eye as a means of connecting to Kadowaki to see if he follows through with his desire. Akachi isn't a bad person deep down, but had a hard life so he doesn't allow others to mistreat him as a Shinshou. He has the respect of his Zokushou from his powerful presence.
