Hasuha is Rentaro's 32nd "girlfriend" from the 100 Girlfriends franchise, a first-year student at Ohananomitsu High School, and a detective who relies on her acute sense of smell to solve mysteries.
Hasuha is a high school first-year student who calls herself a great detective. She has olfactophilia, and her being a detective is largely an excuse for her to satisfy her smell fetish, which is not to say Hasuha doesn't enjoy solving mysteries and aiding others, being a kind and friendly girl to boot.
