Shinobu is shy and timid at first, but opens up to others once they get to know him, showing off his bright and caring personality. He becomes attached to people who show him kindness and support, and shows them kindness and support in return. He is very caring of his friends, who enjoy his company, calling him "healing." Due to having no friends before enrolling at Yumenosaki, Shinobu is also very anxious about becoming bothersome or being hated by his new friends.
