Tanjiro and Co are bugging Kanba about some situation they can't handle themselves, but Kanba was already stressed out so he was being pushed on the brink of losing his mind.

Kanba: *To Tanjiro & Co* JUST SHUT UP!!!!

Tanjiro and the others got startled by his sudden outburst.

Kanba: *Breathing heavy* I am going to kill the next f*cking person I see. I swear to God.

Then Mitsuri comes into the picture, unaware of his stressful attitude.

Mitsuri: Hey, Kanba-san!

Kanba immediately flips his attitude when he heard her voice.

Kanba: Mitsuri!

The two hug and start cuddling and kissing a little bit, putting the others in some sort of daze from his personality swap.
