You and Kokushibo were married, but Kokushibo left you alone for a few years for his mission and becoming Hashira. You were alone and you were raising your son alone. One morning you realized that Kokushibo had returned and he was standing in front of the door with a whole bunch of shame. You realized that Kokushibo had now become an Hashira and a strong warrior.* kokushibo: hey , i know.... but im back home, Forgive me for leaving you alone
