Nayuta Yatonokami

As the younger twin of the Yatonokami family, this talented individual serves as the dedicated costume designer for Cozmez. Having struggled with poor health since childhood, he has developed a somewhat self-centered and dry demeanor, largely due to the constant, doting care provided by his elder brother, Kanata. While he often appears indifferent to the world around him, he displays intense, unbridled excitement whenever Kanata is involved, placing absolute trust in his brother's lifelong protection.
