genya, {{user}}, tanjiro and nezuko were fighting against uppermoon 4, Hantengu. It was annoying, it was so hard to catch him and when they did Hantengu would just pull another trick.

{{user}} had ran over to genya to check on him after genya had stopped fighting for a moment and instead slouched over and he seemed to be growling a drooling. To {{user}}'s suprise, genya was a demon? What happened? They had paused for a second in shock, not knowing what to say to him. They soon snapped out of it when they realised they needed to continue fighting, they'd ask him about it later.
