Hiroi Kikuri

Appearance: Kikuri has long mauve pink hair worn in a side braid tied with a dark brown ribbon and magenta-purple eyes. In the manga, she wears a hanafuda card earring depicting a lotus in both ears.

She wears a simple green dress with a black and white jacket over it and a pair of geta. In the manga, the lower half of her dress has numerous lycoris radiata/spider lily flower patterns.

She also wears black nail polish on both her fingernails and toenails and is often shown with sharp teeth. In the manga, she has a tribal circle-looking tattoo on the back of her right hand.

Personality: As a kōhai in the college days of Seika Ijichi, Kikuri is drunk in most of the scenes during the series.[2] For that reason, she is often fined for causing trouble such as breaking the equipment during concerts, and because of that, she drinks more liquor, so although she earns income at her concerts, she is always short of money.[3]

Once when she was drunk in front of the station, she happened to meet Bocchi who was trying to sell tickets. Despite Bocchi's initial resistance due to her altered state, they eventually bonded, and Kikuri made her perform an improvised session live on the spot where she noticed Bocchi's talents. It was then that a more empathic and mature side of her was first shown. At that time, after visiting the performance of Kessoku Band with a ticket purchased from Bocchi, she frequently appeared in STARRY.[4] However, she still proves herself to be an annoying guest due to her frequent drunkenness.

Unlike today, where she behaves freely, Hiroi had a reclusive, gloomy personality until high school. The reason she started drinking was to suppress the tension of concert performances. She sees a lot of qualities that overlap with her former self in Bocchi and occasionally gives advice as a senpai bandsman. Even so, when she does not consume any alcohol for a long period, her gloomy personality gradually returns depending on her alcohol level.

Whenever Hiroi is sober she turns into her gloomy personality and becomes shy and aloft, and negative.

Relationship: Seika was her senior in her college years and is still a close friend, to the point she always heads to Seika's home and STARRY for shower. Despite her reluctance and annoyance due to her behaviour, Seika always let her be and even taken good care of her wellbeing.

Kikuri got into bands because of Seika and her band which she admired, but the band broke up after Kikuri joined the universities light music club.[5]

Shima Iwashita Shima was her collegemate (and they also went to the same high school, but Kikuri wasn't close to her until college), and together they founded SICK HACK. She is the one to apologize on Kikuri's behalf when Kikuri done things that damages the band's image, even giving anyone involved gifts or letters of gratitude. While she is uneasy of her drunken lifestyle and always warns her about it (Kikuri always ignores these warnings though), she remains loyal on Kikuri's side.

Eliza Shimizu Eliza Shimizu is considerably younger than Kikuri and Shima, but is pretty casual with all her band member. She does not treat her as harshly as Shima does, but she does care about her alcoholic behavior. However, when it interferes with her otaku schedules, she barely gives her any mercy.
