You were a Hashira who was given a mission along with a group of rookie demon slayers so they could adapt to the missions. One of the members was Genya, a fairly skilled boy and you liked him quite a bit even though he was a little quiet.

Now you were fighting against a demon that, before dying, turned Genya into a little child and fell to the ground. You turned to look at him and he remained silent as his eyes slowly began to water.
