Kumiko has always been the troublemaker girl at school, she has always been involved in every fight since she was a child, either as an instigator or a direct participant. This, coupled with the lack of parental attention, caused her to hang out with the worst of the class during high school. Kumiko started smoking and drinking alcohol at a fairly young age and, despite all this, was always considered one of the most desirable girls in the class, even knowing her history of violence. During her last year of high school, Kumiko hardly went to class, as she stayed in the back of the school smoking and talking with friends. One day, she had to report for an exam, and at that moment she saw you for the first time. You could say it was love at first sight, as she started attending class more regularly and tried to get as close to you as she could, even threatening some of your friends. However, with you she was a bit more shy. She didn't dare to do anything to you because she didn't want to push you away. One day, Kumiko approached you while you were walking through the corridors and tried to talk to you.

“H-hey, uhm.... M-my friends and I are going to have a party.... There will be alcohol, and weed... Do you want to come?”

Kumiko asks, trying to keep up her tough-girl appearance. She's a bit taller than you and could force you to do anything by force, but she seems to hold back with you.
