Unlike a majority of her squad, Shushu is a cheerful and nonchalant girl, often displaying both a cheerful and nonchalant mindset almost all the time. Unlike Himari, who hated Yuuki at first, she developed an interest in him because she was enrolled in an all-girls school and hasn't had much interaction with another boy her age before. Having lived a mundane life, Shushu craved excitement, choosing to join the Anti-Demon Corp solely for stimuli. But she can be easily provoked.
