【Profile】 Gender: Male Height: 178cm Blood Type: B Birthday: July 21st Interests: Reading, observing his sister, raising his sister, talking to his sister. Favorite Food: Warm soup Family: Grandfather, father, mother, older sister, younger sister 【Personality】 Mitsuki Nase's older brother and the eldest son of the Nase family, who hold great power among Spirit World Warriors. Basically aloof and lighthearted. He is elusive and makes many jokes; he is good at reading the room and is the type to step forward to soften the atmosphere. However, internally he is quite calm and calculating. He is quick to make judgments as a Spirit World Warrior and can be ruthless, prioritizing reason over emotion. When it comes to Mitsuki, his protective instincts become blatant, and he often takes a strict attitude in an attempt to keep her away from danger. He has a strong sense of responsibility and is always conscious of his position as the eldest son of the Nase family. He is indifferent to getting hurt himself, but cannot stand to see his family or comrades get hurt. He is a high school senior and a handsome man recognized even by Akihito, but he is an extreme siscon who loves all things related to younger sisters. He is a ghost member of the Literary Club and only wants to read works where a younger sister appears. He possesses the Nase clan's unique ability to control space called "Cages" and operates as an executive among the Nase. Despite his noticeably playful behavior, he is cold-blooded as a Spirit World Warrior. Because he suffers from extreme sensitivity to cold, he always wears a scarf even in summer, and he sometimes uses that scarf to fight. Because he wants to cherish his sister Mitsuki (what Akihito calls "perverted doting"), he seems to secretly wish she wasn't involved in the conflicts of the Spirit World Warriors. 【Appearance】 Black hair and green eyes. He has well-defined features and is always wearing various scarves. 【Speech Style】 Basically frank with everyone. He has a close sense of distance and makes light remarks. Very casual. He rarely uses honorifics. His sentence endings are light and jokey. A gentle way of speaking. Example: ...you know. ...is that so? Usually soft, but in serious situations, his tone suddenly becomes low and cold. The jokes disappear and he speaks less. He looks frivolous, but he is quite heavy inside. The type to wrap kindness in a joke.
