キミノカオリ ー Moonlight, Wisteria Petals, and Thunderclap

Yakusoku - Promise

 "Huh. These wounds were pretty deep. How on earth are you alive?"

After the prosthetist unraveled the bandage on my legs, he asked me.

"I dunno."

"Well, either way, we're going to make you mobile again."

He took one wooden stick at a time from the pack he was carrying on his back, and held it up against my leg.

"I see, I see."

"What are you doing?"

"I'm measuring your leg's length. Also, what material should we make your leg with?"

"Wooden? But that'd be too brittle in the heat of battle...."

"I know, let's make it the same material as the swordsmen's swords." The prosthetist suggested.

"Haaah?!" I was so surprised that I almost fell on my back.

"We can make the backbone with a really good iron, and then cover it up with wood. That'd be not too much of a hassle, and it might save you at a dangerous pinch, since it'd be like you're concealing a weapon inside each of your leg."

"O...okay."

"...Does your heart call for that option?" Kanao asked, a little concerned.

"Sure. I still want to be able to fight, in order to protect the ones I love." I said, determined.

"Okay."

"Then. Please, make my legs that way." I requested.

-3 Months Later-

It was winter, and a bitter cold penetrated into every household of the old-time Tokyo. But the Demon Slayers still flew from one region to another, trying to rescue people from the bloody grasp of Muzan's demons, who never hesitated to prey upon the weak. Tanjirou was one of them. Feeling the weather, which turned impossibly frigid in just three short months, Tanjirou gritted his teeth, gripped his blade tight, and charged forward in snow.

"Inosuke! Over there!"

"Ooh! I got it!" Inosuke swung his dual blade, and two demons' necks flew out and tumbled on the field covered in snow.

"Great job!"

"Don't let your guard down, Konpachirou!"

"It's Tanjirou! When will you get my name right?!"

"It doesn't matter in this moment! Look out!"

Tanjirou inhaled as he dodged a fast demon's attack. This one seemed the most strong among all others. It had long, winding arms that covered an impossible range, eight eyes and a giant smiling mouth. In short, it looked really creepy.

"Ugh! This one isn't going down!"

"Let's do a collaborative attack. Inosuke, you strike its head. I'll slice its legs to block his movement!"

"Sure thing!"

Tanjirou jumped forward, performing the second form of Water Breathing. But suddenly, the demon's arms multiplied in its number, aiming for Tanjirou all at once.

'Damn it! This demon, it's been concealing its abilities...!"

When Tanjirou tried to dodge the attack by switching his attack movements, a spark of electricity jolted across the atmosphere.

"Breath of Thunder, First Form. Thunderclap and Flash!"

Tanjirou's eyes widened. This breathing form is...!

"Tanjirou! Are you okay?"

A pair of amber eyes, Zenitsu was there.
