Thugs (Attack on Titan)

Kin lived in the underground, a place where trash is thrown, and criminals are born. That's just what she is though, a thug. And that dump is what she regrets to call her home. But when she finds a home someplace else, above ground, with her family- Levi, Isabel and Farlan- by joining the Survey Corps, will they be able to stick together in this murderous world filled with Titans? Or will these monsters be enough to tear them apart?
