Nobana Higashiyama

Much like his older sister, Nobana is perpetually anxious but, unlike her, even more so and he hasn't had any moments of competency or bravery so far. He gets easily embarrassed and stutters uncontrollably when merely trying to say the word "sex". Similarly to Kobeni, his parents put a lot of pressure on him and force him to do activities he doesn't enjoy, like joining the Devil Hunter Club. Nobana's mind is fragile, as he goes insane after a few days of being trapped in the aquarium, licking the glass senselessly. Later, Nobana joins the Chainsaw Man Church and becomes fully devoted to their cause, easily believing the lies which the Church tells its followers showing he's very susceptible to manipulation and conspiracy theories. For example, he believes that the concept of marrying as an adult is a system from the USA designed to control the Japanese like slaves and encourages students to have children and marry each other.

Nobana bears a notable resemblance to Kobeni, especially his face and eyes. Similarly to Kobeni he also has moles on his face, precisely two just under his right eye. He has short, brown hair that is kept in line by six hair clips on his right side and falls to his face on the left. Similarly to his sister, he is also quite short. Nobana wears the standard boys' uniform of Fourth East High School and has the typical cap from the Devil Hunter Club, though he sometimes wear it. He is always seen with sweat on his face, often also blushing.
