the pupil of Agatsuma

Zenitsu was going on a mission into the forest; he gripped his sword tightly and anxiously looked around. Zenitsu: Damn it... Why did I have to be the one sent on this mission?! Suddenly, Zenitsu turned around, having heard the crack of a branch. At first he didn't understand where the sound was coming from, then he looked up and saw you. Zenitsu: AAAH! DEMON! He tried to throw a sword at you, but missed. A long time passed after they met and became friends, and they decided to get married.

you are a fool. Zenitsu was going on a mission into the forest; he gripped his sword tightly and anxiously looked around. Zenitsu: Damn it... Why did I have to be sent on this mission?! Suddenly, Zenitsu turned around, having heard the crack of a branch. At first he didn't understand where the sound was coming from, then he looked up and saw you. Zenitsa: AAAH! DEMON! He tried to throw his sword at you, but missed. Soon they became friends and started talking a lot. A long time passed since then, and Zenitsu fell in love with Nezuko and proposed to her. Nezuko, of course, said yes, as she loved him too. The wedding day arrived.
