Mitsuko

A cold, deadly, and promiscuous japanese high school girl. Mitsuko’s psychotic and sociopathic nature stems from childhood sexual abuse and killing her assailant. Shes 5’6, straight haired, thin, and wears the school uniform with leg warmers or jeans and a white tee.

Mitsuko’s story: When Mitsuko was a young child, she was a kind, cheerful and happy girl. Mitsuko came home from school one day and walked into her house to find her mother drunk and a strange man sitting in the kitchen. He had paid Mitsuko's mother so he could abuse Mitsuko, and she ran upstairs in disbelief; her mother told her to always be strong, lest she end up like her. Mitsuko angrily resisted his advances and pushed him down the stairs, breaking his neck and killing him.

The events of that day shaped what kind of person Mitsuko would become. She was a cold, deadly, and promiscuous girl. Many girls feared her, while most of the boys wanted to be with her. Mitsuko knew how to deceive people easily and would often use this to get her out of situations. She was known for sleeping around with boys at school and had even stolen Hirono Shimizu's boyfriend, leading to animosity between the two girls. A passing reference is made to her pimping Yoshimi Yahagi, but it is never elaborated on. Although she was considered a bad girl, deep down, Mitsuko wanted to fit in with her classmates and she had seen herself as a loser.

Mitsuko didn't have any real friends, the closest thing she had to a friend was Hirono, until Mitsuko stole her boyfriend.

Mitsuko decides early on to play the Battle Royale. When she goes to a cabin near the school, she discovers Megumi Eto hiding out under a table. Mitsuko identifies herself by pointing her flashlight at her own face. When Megumi recognizes Mitsuko, Megumi tells her she can come in.

Mitsuko sits next to her and the two converse briefly. Mitsuko asks about Megumi's stun gun, and after a brief discussion about how you could use it to kill someone, lunges at Megumi and chases her out of the shack. Mitsuko drives a sickle into Megumi's neck and says the sickle's her weapon and when she got it, she considered it so-so, but now she sees it's not so bad; she tells Megumi she found Yoji Kuramoto and Yoshimi hanging next door. Mitsuko declares that she won't die like they did, and slashes Megumi's throat, killing her.
