Kokushibo had given y/n a series of intense training exercises when he was taking care of her.

It was mainly to keep her busy and to help Kokushibo avoid having to act as well as deal with y/n's brutal comments about how monotonous he was and stuff about how he was a horrible actor-

Either way, the training helped y/n stay at the top of her game. In between that and sparring with the battle doll each time Tanjiro passed out, y/n was at her best.

Yes, I said what I said.

After Tanjiro managed to find y/n shortly after finding Kotetsu who had run off, the little boy had asked that Tanjiro train and become stronger than the Mist Hashira.

After lots of insisting as well as a sparkly eyed stare from y/n, Tanjiro caved and agreed. He knew he'd get his butt kicked but he didn't think it'd get kicked this much.

"Look out." y/n called while nibbling on some watermelon, wincing when the poor boy got slapped across the face with three of the training sticks which the five armed battle doll wielded.

Kotetsu had to switch out the swords for training sticks otherwise Tanjiro would be dead by now.

At first, he was against it, but he went ahead and agreed after y/n had to jump in and fight off the battle doll just as it came close to reuniting Tanjiro with his family early.

"You're too slow, Tanjiro-san!" Kotetsu shouted as him and y/n wandered over to the dazed boy, "Get your act together!!! It's already been five days and starting tomorrow, the doll will be holding real swords again! Y/n-san won't be able to help you then either!"

"I think he's not doing well because you're depriving him of basic nourishment." y/n mumbled and Kotetsu crossed his arms.

"I'm giving him motivation!"

"You're killing him."

"No food today either!" Kotetsu declared.

It'd been like this for the past few days.

The only reason Tanjiro wasn't dead was because it rained during his training, Shiori would distract Kotetsu could Tanjiro could catch a nap and y/n would sometimes bring food to her fellow demon slayer.

That was up until the third day when Kotetsu found out and scolded y/n. After that, he never let his guard down around the apologetic girl and her foul-mouthed cat.

Shortly after y/n stopped taking care of Tanjiro, the poor boy damn near died. He was on his way across the Sanzu River but fell off because of his empty stomach.

The river was nice enough to give him massage as well as a glowing stone that actually had a smell.

Next thing Tanjiro knew, his senses had sharpened.

The battle doll's attacks... he could predict them!

And so, he managed to land a hit on the doll. Though he failed to break his fall and ended up getting all the damage.

"That was 💩 but you landed a hit regardless!" Kotetsu cheered while y/n watched on with bright eyes, "You get to eat today!"

Y/n was 75% sure that Tanjiro was crying as she ran off to go get him some food to eat but didn't stop to ask, not wanting to make him wait any longer.

Basically, Tanjiro can predict the doll's movements with his sense of smell. Pretty cool, right?

Now he has a weapon which gives him an advantage!

Before they all knew it, the day came that Tanjiro was able to keep up with the battle doll. So much so that he was in the position to land a direct hit on it.
