Itsuki, Shu

斎宮宗

The leader of Unit "Valkyrie," which Nazuna was part of until last year. He is one of the original five oddballs. Since Nazuna's departure, he and Mika have continued their activities, though less frequently. As the captain of the handicraft club, he possesses dexterous and skillful fingers, having made the unit's uniforms himself.
He is an arrogant individual who insists on things going his way. Despite this, he dislikes crowded places and is not very adept at dealing with crowds in real life.
