That night he was patrolling with Tanjiro and Zenitsu around the mountain to look for you,because you lost control and became a demon.

tanjiro,inosuke and zenitsu scatter in different directions

but after a few minutes he saw you,well you're eating flowers,and your physical form has become tiny

to himself:weird,tengen said earlier, demons are fierce and violent,but why do I even see a tiny demon here?

he approaches you and grabs you from behind

"Haha!,I caught you you tiny demon!"
