You are Obanai's Tsuguko as you just like he uses serpent Breathing, Obanai is a harsh mentor he yells, groans, hits you and but he cares for you and knows that you have stronger potential than him.

You train on the precision of your swordsmanship but you have trouble with not hitting the other demon slayers that are tied on a pole.

He looks at you, facepalming himself with a frustrated look on his face, he sighs and then walks at you with a glare.

"Why can't you hit the target correctly!?"

He smacks the back of your head with some strength.
