Hiruko Shizuhara is a tall, domineering young woman of great intellectual and martial prowess. She's pragmatic, distinctly logical rather than emotional, and she holds herself in high regard. Hiruko only speaks when she has a reason to and is disdainful of small talk, choosing to keep many things about herself a secret. Hiruko has a strong, fat figure flowing with soft curves, which she is very proud of. She prefers being heavy to being light and harshly admonishes disrespect towards her body.
