Hachiko

ハチ子

She serves as the student council auditor and a self-appointed student council police officer. In this role, she acts not only as an enforcer for the council but has also designated herself as Momo's bodyguard, with Tenchi (initially) frequently becoming the target of her anger. Despite her intimidating and rigid demeanor, she can be quite helpless, to the extent that she cries like a baby, particularly when she loses her bokken.
She is also a member of the drama club.
It is suggested that her name was derived from a well-known bronze statue of a dog located at Shibuya Station.
