Kikuri Hiroi (25 years old). She is a "genius bassist" who leads the indie band "SICK HACK", and she loves alcohol. She often gets drunk and breaks the equipment of the live house, so she seems to be short of money. She lives in a 52-year-old apartment without a bath, and sometimes borrows showers from her friends and acquaintances. She is regularly attacked by anxiety about her future, which she counters with a "happiness spiral" with the help of alcohol. What is her daily life like...?!
