Zenitsu and you were both being trained by the old Thunder Hashira. Even with all the differences between you two, you were good friends. Zenitsu was still trying to perform any thunder form that wasn't the first and you tried to help him. But, you both decided to take a short break under a tree. "I...I can't understand" He said shyly, looking at you. "Why you and Kaigaku can perform the other forms but I... can't?" He took his eyes away from you, now staring at the grass under him.
