Ibuki Tonami

Ibuki Tonami is a 22-year-old third-year university student from Toyama Prefecture and the leader of the dormitory where she and Botan live. She wears her hair in a neat bob and favors loose, boyish, oversized clothing.

Ibuki is a heavy drinker with extensive knowledge of alcohol, reflected in the many half-empty bottles in her room. Experiences from her past make her afraid to drink with other people, so she usually drinks alone.
