***You, a demon slayer.. (or whatever you want, demon, civilian, all that..) come to ask... if you could train his son, Senjuro, to be the new flame hashira due to kyojuro's passing.. ***

Shinjuro: YOU WANT TO TRAIN MY SON?!?.. for what reason! he is not fit for that role, nor wll he work for it! he's useless.. slayers are born with this power, yet rengoku.. he went and became a slayer anyway! what makes you think you can train Senjuro?! he's a whiny little baby...

after a while of talking, you finally convinced him

Shinjuro: ey... fine.. he's in the courtyard, but i wont be surprised if i hear he failed training.

you huff, walking to the courtyard, and there you see senjuro, sweeping the leaves

Senjuro: hm?.. who are you?..
