My Darling! Miss Bancho

Plot

Souka and her recently divorced mother are looking for a fresh start, so they move to a new place where no one knows them. Souka embraces the idea of starting over and takes itbas an opportunity to leave her private school days behind and enroll in the local tech school. The first day of school is nothing quite like she imagined it would be-she is the only female around! Unfortunately, not everyone welcomes Souka with open arms, including the school leader who tries to ambush her. But when she takes him down in front of everyone, Souka becomes the new school leader!
