Midari Ikishima is a supporting character in Kakegurui. She is a third-year student at Hyakkaou Private Academy and the president of the Beautification Council. She is also a member of the Student Council.
Midari has pale skin, short black hair styled in a concave-cut and extremely tiny pupil(s). In the anime, close-up shots of her eye indicate her eye colour to be yellow-green while in the manga they are coloured to be purple. She wears a rarely seen variation of the Hyakkaou Private Academy uniform; a sweater vest in the same colors as the school's black and red blazer, a white button-up dress shirt and a dark pleated skirt, and black socks. She wears the academy's footwear, brown colored loafers with black soles. She also sports purple lipstick and has purple painted fingernails. She forgoes the black tie and has on accessories such as a purple hairband with a heart-patterned bow attached, and purple wrist cuffs with stripes on either one. She has bandages wrapped on either forearm and wears a white medical eyepatch over her left eye. She is also shown to have two piercings under her mouth, on the left side, one piercing on either ear, and a tongue piercing.
Midari is a character with masochistic and suicidal tendencies. This is stated obvious in one of the chapters in the manga in which she cuts her own eye out to pay off the debt to the president. She is shown to be very persistent and overbearing, intimidating or weirding out other students, such as when playing a sadistic game of life or death with Yumeko. She is also very impulsive and has little self-restraint, causing her to look more at immediate satisfaction than any long-term consequences. Due to the fact, that no one wants to play the sadistic games with her she is desperate to gamble with anyone and constantly awaits to 'get off' as stated in a chapter of the manga, by creating dangerous games where one player ends up dead.
She even enjoys a game with one of the Momobamis in which the risk is losing your finger but turns out to be disappointed when the risk disappears. Midari is also a very selfish and narrow-minded character, rarely caring for others' thoughts or wellbeing. She assumes that her mindset is the norm.
She is never concerned with money when gambling, carelessly betting large sums with no worries about potential debt. She does not even clearly remember nor clarify before gambling how much money she owns. Instead, she says she seeks out the risk of being harmed.
Kakegurui - Compulsive Gambler
She first shows up to stop Jun from harrassing Yumeko. When she proposes to him, that she will have sex with him after a kind of Russian Roulette, he leaves. Later she goes to the bathroom, thinking about how much Yumeko impresses her. She pulls the trigger on herself and shoots. When it doesnt fire, she gets aroused and screams in happiness, wanting to feel this thrill again.
Later she arrests Yumeko and Ryota. She takes them to the schools basement to play a game with them. The stakes of the game were, that the winner of each round gets to shoot at the other player. Yumeko played against her, while Ryota was the dealer. Unfortunately for Midari, the gun never ended up shooting. Yumeko explained, that she found out about how Midari cheated on purpose, so that she would lose. Midari wanted to get shot by Yumeko after all. Yumeko states, that she despised this kind of gambling and hates Midari. This treatment however only makes Midari love Yumeko more. She wants to feel agony inflicted by Yumeko and gamble with her again.
In a flash back it is revealed Midari was a formidable gambler, but no victory made her happy. Once she gambled against Kirari and lost. Since she was in debt and wouldn't fit for a lifeplan, Kirari said she wanted to see what it felt like. However, she poked her own eye out with a pen on the spot. That day she realised, that this is the type of pain that thrills her in gambling.
She was on board with the idea of the presidential election, but noting, that the Momobamis would probably lose against Yumeko. Later she got paired up with Yumeko and challenged by Erimi to the Finger Cutting Guillotine. Of course Midari was excited for it. She carelessly cut the threads without any fear. When Erimi got nervous, she shouted at her and mocking her, for being such a coward. That drove Erimi to continue playing. When there were only two strings left, she cut them both at once. She got disqualified for that dn Erimi pulled her finger out, meaning Yumeko won. However Midari was extremely angry at Erimi for there not being any actual danger. But Yumeko scolded her, saying she never wants to see her face again for ruining the thrill, that the last two threads proposed. Midari ran off crying.
She was later seen talking with Yumemi about how she would never get big as an idol and would never be able to catch up to the likes of big Hollywood actresses. This angered Yumemi and caused her to wreck the room, after Midari left.
