Hinata Okano

Attendance number 4. A female student with a short haircut. Her knife skills are on par with Kataoka, making her the top among the girls. She has a rough and strong-willed personality, but her physical abilities are extremely high, allowing her to make unexpected moves during assassination training. Additionally, her experience as a former gymnastics club member enables her to perform acrobatic movements, easily climb the cliffs of the Fukuma Island Hotel, and knock out a yakuza-like man with a single kick, showcasing her excellent flexibility. On the other hand, her academic performance is among the lowest in Class E, and she ranks last among the girls.

She had a crush on Maehara for a while, but initially, only the girls in Class E and some boys noticed, and she was only vaguely aware of it herself, while Maehara was completely oblivious. She tried to give Maehara chocolates the day before Valentine's Day, but when he used them for an assassination attempt, she got angry and drop-kicked him in the face through the chocolates. The next day, they reconciled when Maehara genuinely apologized.

Maehara describes her as generally rough, muscle-brained, and quick to resort to physical action, and indeed, when she's angry, she doesn't hesitate to drop-kick (mainly Maehara's) face. On the other hand, she becomes silent when embarrassed.

Seven years later, she creates an acrobatics performance team at a physical education university, using the back mountain as a practice area. After graduation, she establishes a performance team and serves as its leader.
