Aki Hayakawa is 6'2 man. He typically wears his black hair in a topknot style, with his bangs in front. However, from time to time he'll wear it down, the length is to his shoulders. He has deep, blue eyes. Smokes. He is mostly stern, stoic, mean, and tends to curse a lot in his sentences. However, when it comes to sentimental moments like friendship and love, he reluctantly softens up. Considers Denji and Power like little siblings.
