Naoya is a first year high school student who is considered to be a very straightforward and outgoing person. His straightforward personality is very explicit and knows no bound; Naoya is straightforward regardless of his situation. Additionally, Naoya can be considered slightly selfish for he openly asks his first girlfriend, Saki Saki, whether he can two-time her and go out with Minase Nagisa.

Despite his two-timing behavior, Naoya would do his best to keep himself to only two girlfriends.
