Demon slayer x male reader

Tsuguko

Morning after first test

(Y/n) was lying in bed, he wasn't sleeping though as he was in great pain between his physical injuries he'd been sustaining and the poison running through his veins

His blanket was only covering his legs and his Hakama's top was hanging by his waist

Then tengen entered the room throwing the door open

Tengen:wake up damnit!

(Y/n)'s eyes snapped open as he fell off the bed

Tengen:your training starts now! Get up!

(Y/n) quickly started putting his sandals on while putting on his damaged haori as he ran outside with tengen yelling profusely at him, the sun wasn't even up yet

Nearly an hour later (y/n) was walking through the forest with tengen, (y/n) was sweating as he was still poisoned and injured

Tengen:as your mentor my job is to make sure your ready to face demons. So I'll be educating you how I see fit. Once your ready you'll go through final selection at mount fujikasane like all other demon slayers.

(Y/n):I understand sir. You must've been a demon slayer a long time to become so good at it.

Tengen:I'm only 20.

(Y/n) nearly fell over from the shock and amazement

(Y/n):wow you must be a natural at demon slaying then mr.Uzui

Tengen smirked

Tengen:but there's other hashira who are much more talented than me.

(Y/n) remembered to last night seeing the beautiful women with tengen

(Y/n):mr.uzui who were those women last night?

Tengen:you'd be referring to my wives, Hinatsuru, Makio and Suma.

(Y/n):wa-wait they're all your wives?

Tengen looked over his shoulder with his smirk

Tengen:but of course.

(Y/n) was amazed yet again

(Y/n):*wow mr.Uzui is amazing.*

A few minutes later (y/n) was standing at the beginning of the course again

Tengen suddenly injected him again with another needle causing (y/n) to fall down from the pain

Tengen:I didn't give you permission to kiss the ground! It's not break time so get moving!

He pulled out a shinai and smacked (y/n) on the back with it

A few minutes later (y/n) was barely jogging through the obstacle course with tengen jumping through the trees over him screaming like a drill sergeant

Tengen:SLOW SLOW SLOW!!! THE HELL ARE YOU DOING?! CAUSE I DON'T HAVE A CLUE!!

(Y/n) fell into a pitfall trap

Tengen:THIS IS BASIC RUNNING!! IF YOUR GONNA BE THIS SLOW THAN SLAYING DEMONS IS A DREAM WITHIN A DREAM!!

Later (y/n) came limping into the back yard of Tengen's mansion

Tengen:GET BACK UP! YOU'RE RUNNING IT AGAIN!! YOURE STAMINA IS PATHETIC AND MOVEMENT NEEDS WORK!!

During his second run (y/n) stepped on another plate causing a massive flat form of sharp barbs to spring up and fall towards him which he barely dodged

However he did hit a rope snare trap which left him handing upside down from a tree branch

Tengen:GET DOWN FROM THEIR RIGHT NOW!!
