『Hina Fuuma』

Kinji's underclassman. A Lezzad freshman, enrolled in class 1-C, she has her black hair usually pony-tailed in the back. She also wears a long muffler around the neck, a Fundoshi for underwear, and appears in traditional ninja garb. She is rumored to be a descendant of a famous ninja lineage(presumably decedents of Fūma Kotarō).

When they were in middle school together, she and Kinji sparred. At that time, Kinji happened to be in Hysteria Mode and he subdued Fuuma like a child. Ever since then, she greatly respects Kinji and calls him"Master". She works part-time in order to pay for her tuition as well as to make ends meet, which she refers to as"training". She is Kinji's Amica, which is when a Junior(Kinji) or Senior acts like a big brother/sister for a freshman(Fuuma) and essentially shows them the ropes about various things whether it is skills, state of mind for situations, training methods, nuggets of experience, etc.
