The Gin family (ジン家 Jin-ke?) is one of several families that live within the Walls. It is the family where Eld Gin of the Special Operations Squad hails from.
Eld Gin is first introduced as a member of the Levi Squad.
Eld later participates in the 57th expedition outside the Walls where he is killed while battling the Female Titan.
When news about the Scout Regiment's return is heard, the Gin family prepares for Eld's safe return.
