Impossibility

It takes place in an alternate universe of future Japan, where the capital city is surrounded by crimes and yakuzas. No women or children are safe. So who is there to help them none other than Tsukasa, an action packed 14 year old kid. But there is a problem, Tsukasa and her (yes, Tsukasa is a GIRL) three brothers are now orphans. Ohhh, how will they live now? Aah, she can go ask her rich, powerful, almost to be leader of a yakuza classmate, baka-Ryuji, to help them. Will this request go smoothly or wreck more havoc for her family?

Kumiko, who is the granddaughter of a notorious Yakuza boss, only has one dream and that is to become a teacher. Her first teaching job is at an all-boys private high school. But she is assigned to Class 3-D, known for its delinquent students. She, who grew up in a much tougher environment, thought that teaching these kids some valuable life lessons won’t be so difficult. In addition, one of her students, Shin, seems to be interested in her. Hiding her true identity as a yakuza girl always puts her teaching career on the line especially when these kids keep getting in trouble.
