Gentuki Oba-san

An old woman who spends the majority of her time going after discounts and sale events. To the annoyance of every Traffic Division officer in the Bokuto Precinct, she does so relentlessly and is perfectly willing to commit any traffic violation in order to get to the sales location faster, counting on the reflexes of people or vehicles she was about to collide with rather than her skills in operating a scooter to avoid accidents. For transportation she uses a motor scooter (with a 50cc engine, hence her nickname), which tends to be overloaded with groceries and other merchandises that she purchased during discount events.
