Hanabata was born to Toru Nohkins, president of Nohkins Sports - an equipment making company, and his wife. She grew up with her friend, Tokishikko Dana.
Hanabata is tall and curvy, sporting the largest breasts of the girls in the party. She has short pink hair and green eyes. She typically wears silver armour over a white and red dress.
Before she joined the guild, her father saw a file on Kikuru and told her of his true accomplishments. Though she was envious that her father praised him at first, she later develops a crush on Kikuru.
When she turned eighteen, she and her childhood friend Toxico registered to join the guild and become members of Kikuru's party under his tutelage.
Hanabata is normally calm and mature, but she can be easily flustered when it comes to lewd situations. She is humble, as she doesn't let her status as heiress to her family go to her head.
When she enters Flower Frenzy mode - her ultimate, she acts like a drunkard and attacks any monster with gusto. Hanabata will also throw herself (with superhuman speed and strength) at Kikuru when given the opportunity. Once she's back to normal, she has little to no recollection of her actions, and her servants work to ensure she never finds out what her Frenzy mode is like.
