Hunting Demon: Part 2

(A/N : I'm realized that Muichiro is still 10 years old in this time (4 years BC) so he still with his twin brother and still not joining Demon Slayer corp, but since this is fanfic a little change might be fine... probably)

After the woman leave, Levi and Yuki then countiued walking towards the direction the woman had told him about.

"What do you think about the demon that hunting in this city?" Yuki asked when they on their way.

Hearing Yuki question, Levi pondering that for a moment while holding his chin. "If we take the fact that 15 people have disappeared in this town, then I think this demon is pretty strong"

Levi knew from Kanae that the more a demon eats humans, the stronger the demon becomes. And you could say that the demon they hunted had already eaten more than 15 people so he concluded that the demon might be enough to give them a test run with their Breathing Style.

Yuki nooded at that, and asked again. "When are we going home? Even though I'm enjoying being here, I'm also starting to miss mom and the others..."

Even though she wants to have Levi's attention completely for herself, but that will make the harem plans for Levi fall apart, especially when she herself pushed them in the first place to become Levi's lover. So it would be hypocrisy for her to do that

Levi nodded in understanding because he also started to miss his other lovers too, he then said to her. "Maybe after this mission is over we can go back for a while and take them too to this world."

Yuki then snickered at his word and said. "Yeah we cannot forget about Kocho sisters after all~"

Levi then give her a deadpan stare and said. "Well... It's not like I don't like them, so I will let it pas." Although his time with the two Kocho sisters was short that is less than a month. But Levi was quite attached to them after the few interactions they had during their stay at the Butterfly Mansion, moreover it was hard for them to hate and not get close to Kanae with her personality.

"Fufufu~ That's my brother." Yuki then give him a kiss on the cheek. Not wanting to lose to his sister, Levi then gave hee a kiss too, but instead of kissing her cheek, he kissed her on the lips.

"Hehe~" Yuki smiled in delight after receiving the kiss.

They continued to enjoy their time like that until they didn't realize that they had arrived at what they thought was the home of the 'kidnapping' victim.

'Definitely something fishy happening in here.' Levi thought in his mind while looking around. Unlike the center of the town that has quite a lot of people, here he didn't even see anyone on the street but themselves and the doors and windows of the houses around them were tightly closed.

Closing his eyes while he actived his [Observation Haki], Levi trying to focus in his senses and finding the said demon. His gaze then sharpened at the shina soba shop in front of them. "Let's go." Levi said simply, he then lead Yuki to the building in front of them.

Yuki just follow him and didn't say anything, although she and Levi are usually playful during normal times, there are times when they are serious when the situation forced them to. So looking at Levi's state after he used Observation Haki it was clear the situation was rather serious.

"Welcome, what would you like to ord-" When they arrived a waiter came to receive them, but she cannot finish her sentence when suddenly Levi knocked her off by chopping the back of her neck.

When Yuki saw what Levi was doing, she looked him in wonder because she clearly didn't look like a demon at all.

Knowing Yuki want to ask something to him, Levi then put his finger to his lips to told her to be quiet.

Levi to a stance and muttered. "Wind Breathing: First Form: Dust Whirlwind Cutter" He then dashed forward at blinding speed and slashe continuously in horizontal cyclone pattern.

In blink of eye he then arrived at the kitchen where the demon he saw before by using Observation Haki. The demon's appearance was still humanoid but with two additional arms growing from his back, he also has gray skin and a singel horn growing from the center of his forehead.

Levi's surprise attack seemed to work because at this moment the demon was covered in wounds all over its body and several parts of its body were also cut, but unfortunately it regenerated shortly after that.

Seeing this Levi could only sigh in unfairness in regeneration department. Levi hasn't had attachment to humans like MCs in general, if he is given the choice between being Human or Dragon, without a second thought he will choose a dragon, it doesn't mean he wants to be like a demon in front of him, because after all he is a system user and in the future he maybe can change his race to the better one.

"How dare you to come to my place!!" The demon shouted after all his wound is completely closed and regenerated.

'His place?' Levi thought, he looked around and noticed that the kitchen the demon was occupying had several human body parts in it such as legs, arms, even a head hanging from the ceiling.

He want to puke up a little when seeing that, even though he had already killed a lot of people, but it was different from seeing someone mutilated because he usually gave the people he killed a quick death, fortunately he has quite resistance to not puke up there and there with all his 'experience'.

Meanwhile when Yuki enter the kitchen and seeing the condition around, she almost has the same reaction with Levi, but what was different was that her dinner was forced out of her stomach.

Seeing this Levi smiled helplessly and then quickly focusing on their enemies once again. The demon then took out of four butcher knives out of nowhere and was ready to attack them.
