Makoto Itou features in the "Valentine Days" OVA among his broader media appearances. As the eldest child living with his divorced mother, a nurse often absent due to long work hours, his unsupervised home life facilitates opportunities for sexual relationships. He developed domestic skills like cooking and housekeeping out of necessity, while his hobbies include video games, listening to music, and crafting jewelry. Personality-wise, Makoto exhibits indecisiveness and weak willpower, struggling to reject romantic advances. Often appearing gentle, he can be easily manipulated or become manipulative himself. In "Valentine Days," multiple girls—Sekai Saionji, Kotonoha Katsura, and Otome Katou—pursue him with Valentine's chocolates. His inability to choose triggers a chaotic chase where the girls corner him on the school rooftop and force-feed him their chocolates. The OVA concludes with Setsuna Kiyoura giving him a large box of chocolates, later revealed as a prank by Taisuke Sawanaga, leaving Makoto horrified. His character development diverges significantly across different media. The anime adaptation depicts him becoming increasingly selfish and sexually driven, culminating in his death. The manga portrays him as more genuinely conflicted and remorseful regarding his infidelity. In the original visual novel, his personality and endings vary based on player choices, ranging from committed relationships to destructive outcomes. The "Cross Days" manga depicts him as a predatory figure. "Valentine Days" presents a comedic exaggeration of his indecisiveness and the romantic conflicts central to his character.
