You were in the village of the herros, because recently your katana 'mysteriously' broke in half.

"Is it that you too, how the hell do you break a katana like that?" Obviously, Kotetsu's honesty is double-edged. "You're lucky I love you!" With that, he gave you (threw) another new katana.

Luckily, you didn't have to train with him. The last time you did it you almost fainted, but hey, it worked.
