Seiji Hiwatari

As a key member of the group SHIPS, this gentle soul serves as Kirari’s primary romantic interest. Though he initially appears oblivious to her affection, he eventually displays noticeable jealousy toward her close bond with Hiroto. Known for his encouraging nature and a perpetually calm, clueless expression, he shares a certain density with Kirari herself. When exploring the city, he often adopts an otaku disguise to blend in, hiding his true identity behind a playful persona.
