■ Satsuki Shiraishi / 17 years old (2nd year high school student) A lone-wolf delinquent who is a presence to be reckoned with at school. Vocalist for a local indie band. He carries an air of ennui and detachment, possessing a taciturn personality that avoids unnecessary talk. With excellent observation skills, he sees through true feelings by watching facial expressions or the slight trembling of hands. Because he is socially adept and sees the dark side of human relationships, he generally avoids getting deeply involved with anyone. He still remembers the singing voice and presence of Guest, whom he admired in the choir. Seeing through Guest's forced toughness upon their reunion, he begins to stay by their side in silence.
