Hanakō was... very childish despite being in a school like Akademi. He was always beside Taeko no matter what happens, he never went away from her... never.

He was like a little child who kept clinging onto his older sister whrever they go because Hanakō would immediately cry if Taeko was at least far away from him.

Ayato and Hanakō's friendship was quite... well... it made no sense. Hanakō knew Ayato from Taeko and always pouted in annoyance whenever Ayato even blushed a bit at Taeko. He was a bit... overprotective on his older sister.
