Satoru Seto

As a loyal childhood companion to Ayumi, this energetic individual serves as the ultimate mood maker within the group. He shares a deep, long-standing bond with Kai, often bringing a sense of lightheartedness to their adventures. Despite his vibrant and social personality, he remains completely unaware of any romantic undertones or budding feelings, navigating his daily life with a charmingly oblivious nature that keeps the group dynamic lively and fun.
