Hanabi Yasuraoka is the main female protagonist in Scum's Wish.
Hanabi is a very beautiful and attractive young girl (that causes many of the boys in her class to confess their feelings to her) with chin-length black hair that has purple tint with bangs hanging over her eyebrows her eye color is an ombré of purple and blue, sometimes appearing green (in the anime).
She is usually shown wearing her school uniform, which is a red ribbon, a short-sleeved white collared shirt underneath a dark blueish purple vest and a slightly green grey skirt. She also wears black knee-high socks and school shoes, sometimes wearing the red gym shoes as well.
When she's with Sanae Ebato (Hanabi's closest friend), Hanabi is an outgoing and regularly cheerful girl, in contrast to when she's in the presence of Narumi Kanai (Hanabi's love interest), whom she feels timider with and can come off as hostile. But when around Mugi Awaya, she feels more at ease and lets her guard down because she trusts him a lot; he's the only one who understands her worries and who she can share her deepest troubles with. She's often sarcastic and brutally honest to the point others may perceive it as arrogance. This is one of the reasons why Mugi calls her "horrible" when she blatantly told Noriko Kamomebata that she finds her a nuisance. Regardless, Mugi doesn't seem to mind her honesty and even states that he likes her as a whole. Hanabi is jealous whenever some friends of Mugi approach him. That's when Hanabi started to get more jealous.
She's also observant and analytical, shown when she figured out that there's more to Akane Minagawa than just her clumsy, gentle side, even comparing her to herself.
