Gojou, Wakana

Wakana is quite tall for his age, standing at least 180 centimeters. When Marin asked him his height, he was interrupted before he could finish saying, meaning that he may be taller than 180cm. He has short, black hair and gray eyes, along with a tiny mole on the outer lower corner of his right eye.

Outside of his school uniform, he is always wearing a samue, a general work outfit consisting of a blue suit jacket and pants, with a simple white shirt underneath. He wears wooden sandals and wears a white headband while working. He tends to have it over his shoulders when not wearing his headband.

At the start of the series, Wakana was a withdrawn person in high school, having no friends and a secret love and admiration for hina dolls.His solitary attitude makes him rather submissive with others. Wakana is rather shy and modest, not doing well with embarrassing or lewd topics. Wakana doesn't appear to have much of a life outside of his grandfather's store and helping Marin, as he always wears his work attire outside of his school uniform, and often spends his free time either sewing or painting hina doll faces.
