Наруми's 16-year-old classmate, Ayaka, introduced him to all the members of the "NEET" team. She works at a ramen shop located under Alisa's apartment. Ayaka is a cheerful, energetic, kind, and responsive girl. She does not participate in the investigations, but she sometimes helps Narusu. It is also revealed that Ayaka has a brother who is involved in a drug distribution case that the "NEET" team is investigating. In one of the episodes, Ayaka mysteriously falls from the school roof and falls into a coma. When she recovers, she suffers from amnesia and does not remember Narusu.
