This is my second ever fanfic, so be nice XD

R&R, please! Motivation is hard to come by these days and seeing your thoughts really helps

I'm planning for this one to be multiple chapters, but we'll see how it goes

It was always the easy ones.

At least, that's how it was for Zenitsu. There was always a catch. No mission was as easy as the crows said it would be.

So when he, Tanjiro, and Inosuke got a supposed easy mission, he was the only one on edge. The other members of their trio seemed all too relaxed. At least, that's what it looked like to Zenitsu.

It was also why, when the seemingly weak demon revealed it's blood demon art, Zenitsu was the only one who wasn't surprised.

The demon had been praying on humans in the village of Sawara. His apparent favorite was blondes, which did not help Zenitsu's anxiety, and had eaten around 15 people by now.

The aforementioned demon art came in the form of the retractable spears sprouting from the demon's wrists. They sorta reminded Zenitsu of lion claws. The demon also had insane speed. The trio had yet to land a blow on it, much to the demon's entertainment.

"How the heck is it so fast!?" Inosuke growled, climbing out of the rubble the demon had thrown him into.

"It's blood demon art, I think." Tanjiro responded, as he set down Nezuko's box to increase his speed.

"So it has two of them? Ugh, I knew this one was gonna be hard." Zenitsu groaned, but had to focus on blocking a blow from the demon's spear with his sword, effectively shutting down his complaints.

"I've always loved girls… She's not blonde, but she'll have to do" The demon mused, preparing to pounce on Nezuko. Apparently he could see Nezuko in the box. Zenitsu inwardly groaned. Three demon arts.

When the demon's comments reached Tanjiro's ears, his sound changed. Zenitsu froze. He had never heard Tanjiro this mad.

Insouke managed to sneak behind it and cut its back, but was quickly knocked aside by the demon, his back already healing.

While the demon was distracted, Tanjiro placed himself in front of the box, protecting it with his body and glaring daggers at their adversary.

Then the demon activated his speed, and disappeared from their sight. Well, Inosuke and Tanjiro's sight. Zenitsu could see him, as he also had super speed.

His heart sank into his stomach when he saw the demon speed past Tanjiro and the box, to then turn around and face them from behind. The box was unprotected.

Zenitsu saw red. If he didn't do something, Nezuko would die. Tanjiro and Inosuke weren't able to see it, and weren't fast enough to do anything about it.

Right as Zenitsu saw the demon's plan, all of his fear left him. No one hurt Nezuko.

No one.

He started his Thunder Breathing and rushed over to the box, stopping in front of it right as the demon started towards it. He didn't have time to pull out his sword to block the demon, so he stayed where he was and acted as a shield, not caring for his own safety at all.

The demon extended his spears and landed a blow. Right through Zenitsu's stomach.
