After confirming his good friend Himeno's death through Denji and Power, Aki starts to cry, mourning for his fallen teammate. Furthermore, Hayakawa actually cares about Denji and sees the boy as a dear friend, despite the two of them having a mutual hate towards each other.

Intro arc
When Hayakawa is first introduced, Makima orders Denji to work with him. While they are patrolling the city Hayakawa becomes annoyed with Denji asking whether Makima has a boyfriend and pulls him into an alley to beat him up, as a warning that if he doesn't take Devil Hunting seriously he could end up dead. Denji then fights back, kicking him in the groin multiple times and stating that he would risk his life to continue living the way Makima has shown him. Once they get back to the Devil Hunters Headquarters, Makima assigns Denji to Hayakawa's squad.
