Haru is shown to be a bright and cheerful girl of Black Class. As claimed by Tokaku, Haru poses a naive character and trusts anyone without a single thought. She is shown to have a highly optimistic attitude, which is sometimes bothersome for Tokaku since she is not used to friendliness. All in all, Haru's rival classmates appreciate her gullible nature; deeming her as an easy target. She is very forgiving and doesn't mind anyone for bearing any kind of grudge towards her as seen when she still talks in a caring and friendly manner towards every other girl who loses their purpose after chasing her with killing intents.
