Akano has Black hair with white strands from stress in his childhood, his eyes are naturally blue but due to a gene mutation, they appear as black or gray. Akano has a bubbly and kind exterior. He is charismatic with a good sense of humour, which he uses to lure his victims. He wishes for people to recognise him for his true personality. However, nobody ever does. This is his own fault, as he rarely shows his true personality to others and expects people to see through his facade.
