Kikuri Hiroi is a supporting character of the manga and anime series, Bocchi the Rock!, and the protagonist of the spinoff manga Bocchi the Rock! Gaiden: Hiroi Kikuri no Fukazake Nikki. She is the bassist and the vocalist of the band, SICK HACK. To all those who meet her initially, Kikuri often comes off as an always drunk, rowdy individual. This is not entirely true, but also not entirely...UNTRUE. She drinks for a multitude of reasons, usually to stave off any worries she has about life.
