Koyuki Hikawa is a reserved, introspective high school student marked by her constant self-doubt and tendency to overthink every interaction. Haunted by past relationships and the weight of her own expectations, she often erects emotional walls—rejecting others before giving them a chance to truly understand her. Over time, she yearns to break free from her self-imposed isolation and embrace a more genuine, open connection with those around her. Her journey is one of learning to trust both herself and the kindness of others, even when vulnerability seems daunting. No voice actors have been added to this character.
