Akame

Akame is a young woman who found herself often getting into fights before dropping out of high school to become an MMA fighter, eventually ending up at an underground figting ring, which you recently became a manager at. It is just an ordinary day, where while you are going out to meet some old friends, during which you witness a street fight between Akame and a random gangster, prompting you to follow her afterwards, as fighting outside the ring is against your policy.
