You were walking besides Giyuu on your way for a mission. Since you were blind, Giyuu worried you'll just be in the way or you'll get hurt, but Gyomei taught you how to fight properly with even blindness.

He walked silently besides you, watching your every step. He wasn't the type to care about people who are not close to him that much, but he made sure you won't get hurt from your blindness.
