The troubles of having a harem

Another month passed since Arthur arrived in the world of Demon Slayer and now it was time to take the girls out of his inventory. Right now he was in his house and it was nighttime outside, and the room was particularly dimly lit.

Before he could take the girls out of his inventory, he needed to test whether the planet was habitual for the humans of HOTD world and Marvel world or not.

And for that, he took out a small contraption from his inventory.

It had the parameters of HOTD world already saved in it to compare with the data acquired from the input sensors. Fortunately, the results were positive, his girlfriends and his soldiers won't die on this planet if he took them out of his inventory.

If the results had come out negative then all the living humans in his inventory would have to stay in there until he could return back to the HOTD world/universe. As he could only open a portal to the HOTD world/universe if he was in the Black Void and asking the penguin to return to the black void without completing the mission was the same as abandoning the mission.

Basically, he can't switch between two verses when on an ongoing mission.

Anyway, after he found out that the Earth of Demon Slayer universe was safe for the girls, he took all three of them out and woke them up.

"Art, in which world are we?", Shizuka yawned as she stretched on the couch.

The blonde nurse was 32 now yet she hadn't lost her charm one bit, instead, it seemed to be increasing, though it could be just Arthur's lovestruck eyes...

Right now she was wearing a peach-colored Kimono and her fluffy blonde hair was tied in a beautiful bun.

While Saeko narrowed her eyes on Arthur... even though the light was too dim to see, she couldn't help but notice it. "What's up with your appearance Arthur, it seems like you have regressed to your younger self!"

Saeko couldn't help but giggle seeing Arthur's younger appearance. Like Shizuka, Saeko was also wearing a Kimono, although it was azure in color.

She was 23 now, still the same seductive yet composed beauty. And she had acquired a really killer physique, her curves have widened slightly though she still has her slender charm. People could easily mistake her for 18.

Shizuka also stared at him and then her eyes widened. "Oh my god, he looks so cute! Just a while ago he had his beard covering all his face and it's all gone adlfjasdofj" She squealed, not able to hold her excitement.

Arthur sighed, it was embarrassing for him to let them see him in this state, he knew it. That's why he lowered the lights so it buys him some time and he slowly reveals that to them but seems like he failed. Though he wasn't too young, his age was now even lower than Saeko... he didn't like it... this 'Shota among milfs and onee-san' situation.

"What's up with your eyes Arthur, although barely noticeable, they're glowing..." Saeko stood up and walked closer to him, she caressed her palm across his face and neck.

Her brows twitched as she noticed another change in him, her nose went closer to his neck, she sniffed. "And you even smell different."

Arthur gave the scowling Saeko an apologetic smile as he gestured for her to sit down with the other girls. Tough slightly glad about the change in the topic.

Sighing he pulled out a chair from the inventory for himself in front of the girl's couch to sit on.

"To answer Shizuka's query first, we are in the Demon Slayer world. But more importantly, you three don't feel weird, right? This is a different world! Take a few breaths."

In the past, he had told a few things related to his mission in this world and the story of the Demon Slayer world. It also served as a good bedtime story of sorts for the girls.

Anyway, the girls didn't feel anything off about the atmosphere.

"It doesn't even feel like we've switched between planets," A tanned woman muttered.

Oh, Rika, had also decided to join them, even though she wasn't one of his girlfriends because she was worried about her friend, Shizuka, or at least that's what she said.

Unlike the other two who were wearing traditional Japanese outfits, this 31-year-old woman was wearing a red deep-neck top, a black leather jacket over it, black denim, and white mid-top sneakers.

Despite what Rika said, they should be feeling a change as even though pretty low in amount, the gravity of this world was in fact slightly greater than that of the New Earth. But for some reason, they were feeling fine...

'Maybe another feature of my Inventory.'

Well, it was something that didn't matter right now, so Arthur will just keep this observation in the back of his mind for now.

"Girls," Arthur sighed, "This world may seem peaceful and calm on the outside, but you do remember what I've told you about it right?"

"Demons..." Saeko muttered with eyes filled with disdain.

One world after another, it was always these human-devouring monstrosities...

Oh, well... finally, after two years of peace, she'll have the opportunity to let loose her sword again.

Arthur nodded, "But it won't be over in a day as I had thought earlier. The specifics of the mission have been changed... I still need to kill Muzan. But now, even I don't know exactly how long it might take. If I had to guess, then about two to three years I think... And also..." he paused, "I've become a demon."

Saeko's eyes widened and so did Rika's but Shizuka just tilted her head with a small cute hmm.

"Ah..." Saeko wanted to ask a multitude of questions but her mouth was frozen due to the shock, her composed expression broke completely.

She could never imagine that Arthur would become a human-devouring creature... More so, from his tone, it seemed like he became one of his own free will.

An image of him hungrily devouring the guts of the human he just killed with his claws... An image of him killing children and eating their mothers conjured in her mind.

"Why..." A shaken mutter escaped her mouth.

"Hey, now. Wait wait wait! I know what you're worried about but even though I've become a demon, it's not like I go around killing humans to eat them despite what I told you what they usually do. You see I am a special kind of demon!" Arthur couldn't help but panic slightly seeing Saeko's teary face, he quickly gave her an explanation.

"Special kind? Those upper moons?" Rika accused. It seems Shizuka shared the story of Demon Slayer World with Rika, huh. "Don't they kill and eat even more humans than the normal ones, you told us that yourself!"

He glared at Rika to shut her up which made her flinch slightly and upset and slightly angry too, although she didn't say anything.

"Look," He sighed, "My genetic constitution was way different than the humans of this world. And that resulted in a complex mutation which is why I am as disgusted and repulsed with the thought of tasting human flesh and blood as any normal human... So, there is no need to worry."

At this Shizuka stood up with a shocked expression as if her whole world was taken away from her, tears almost at the brink of falling down from her delicate golden eyes, "But doesn't that mean you won't be able to have babies with us?"

Arthur smiled helplessly, a small chuckle escaped his mouth as he hugged the blonde tightly, "Let's not be too sure about that, maybe the babies will be half demon half human, won't they be just most adorable little half demons?" He caressed Shizuka's head as he gently comforted her. "Besides, after the mission is done, I can go back to how I was before. I can do that alright..."

She was worried that if his genetics have changed then won't be able to reproduce with her or any girls for a matter of fact. But Arthur's comforting worked as she nodded a little. "Hmm," She smiled in his embrace

'The troubles of having a harem...', Arthur sighed.
