Hey guys, Marveller here!
Honestly, I never expected so many of you guys still waiting for this fic. Even after ignoring the spams, the number of comments surpassed 100!
Here is the new chapter for Omniversal Mercenary and before that a brief summary of the demon slayer arc. ( For the summary before that read Chapter-> Summary till demon slayer arc.)
================
Summary
---------------
Arthur accepted the demon slayer world's mission. For this he needs to kill muzan, save a few wifus from certain death, including Daki too! He also needed to save Tanjiro's mom, which is the sole woman in the optional mission category.
FYI, optional missions in most cases are more difficult than the regular missions.
The day he arrived in demon slayer world, he captured a random demon to experiment on him. After experimenting on him a bit, Arthur decided to become a demon himself. The same night he went to Tanjiro's house, there he stuffed the whole Tanjiro family into his inventory expect for Nezuko as she was needed for the plot.
When Muzan came, he was impressed by Arthur's fake villainous act and decided to make him a demon with the prospect of becoming an upper moon.
Arthur's absorption of Muzan's blood was extremely good, Muzan was even more impressed.
After becoming a demon, he took out Shizuka, Rika, and Saeko and assigned them their own missions to help him.
(He's only dating Shizuka and Saeko, Rika came with him because she is worried about her friend. Nothing more! At least that's what she says...)
Saeko was sent to train to become demon slayer with Tanjiro. To keep a track of the plot and inform him about any butterfly effect.)
Shizuka and Rika were sent to butterfly mansion. For learning about demons and the science of this world.
Arthur experimented more on the demon he caught on the first day and then turned him into an undead with undead virus of HOTD world.
Ryoma become Arthur's servant.
But this exposed his plan to Muzan. He sent Akaza to fight with Arthur. Arthur somehow made Akaza run away but Muzan is now aware that Arthur can make every demon in existence into his own puppet. And that's why he's hunting him.
Anyway, Arthur calls demon turned into undeads as Demon Undeads or simply Demonic Undeads.
Arthur then made a contact with Tamayo and asked her to help him to find a way to turn undeads into demons. He'll call the undeads with the power of demons as Demonized Undeads.
They were successful after a year and in that year Arthur fell in love with the lady. He even took her to a date after which he become horny and decided to fuck Shizuka.
==========================
While reminiscing about Shizuka's bountiful melons, Arthur accompanied the beautiful Tamayo back to the hidden estate.
Arriving at the house, he made his way to Tamayo's assistant, Yushiro's room. He knocked a couple of times and waited, soon Yushiro came to open the door.
"What is it?" Yushiro exasperatedly asked, his eyes were red, and his eyelashes wet.
'He was crying, huh...'
Ignoring the sorrow of the green-haired boy, Arthur asked for the thing he approached him. "The usual, a demonic-scent-masking parchment and presence concealment parchment."
Yushiro nodded and went back into his room to get it and then handed it to him without any questions.
Arthur had already asked him for this useful piece of parchment whenever visiting one of his lovers. He can't have someone follow them for various obvious reasons after all.
At midnight, he attached the parchments, which made him invisible and unsmellable, on the back of his neck, and flew off to the Butterfly Mansion.
He had already dropped a message to Shizuka, informing her of his late-night visit.
Before entering the Insect Hashira's estate he once again made sure that the parchment was working. He stealthily made his way to Shizuka's personal room and entered it.
She was already sleeping, tightly wrapped up in her blanket. Arthur stored the wrapped-up figure in his inventory along with her whole bedding.
He then flew to his cabin in the woods. Removing the parchments, he headed straight to the bedroom and took out Shizuka from his inventory, but...
.

"So, how come it's you?" Arthur cocked his brow at the tanned woman who had a sheepish expression. "Don't tell me she had a hand in this too."
Rika pursed her lips and nodded.
Arthur smiled, "So, Rika Minami, the best friend of Shizuka Marikawa. The one who had never liked the idea of a harem and, for many weeks, even discouraged her friend from being in a polygamous relationship with her handsome boyfriend... Accepts getting help from the same friend to get into the pants of the very same woman's boyfriend, huh?"
He added, "Quite an irony, isn't it?"
Arthur was really enjoying it.
"...." Rika just kept quiet and nodded.
She wearing a loose red kimono which displayed almost all of her cleavage and was sitting on the floor in a seiza while Arthur was standing, towering in front of her.
"And what's worse my girlfriend wants me to satisfy her friend's sexual urges, oh poor me, what in the hell should I do?" Arthur cried, hugging himself as if to protect his chastity.
Arthur really didn't mind it, in fact, on the day Rika proposed to follow the group to another world he somewhat expected that one day or another Rika would end up joining the harem, but this situation was kinda funny and quite unexpected from Rika.
'By the way, it was very much expected from Shizuka.'
"You should... um, comply?" Rika looked at his face, blushing.
"Oh, you'd just want that, wouldn't you! But why should I?" Arthur frowned, barely holding his laughter back.
"Because I'm sexy?"
At this, both of them couldn't hold it any longer and gales of laughter erupted in the room. Well, they were really good friends and a banter like this was funny, after all.
After a few moments of laughter, they calmed down and a beat of silence ensued.
And Arthur broke the silence first as he sat on the floor in front of Rika, he looked seriously at her, "I hope you know what sleeping with me means. I won't let you off with just a one-night stand. So, what changed, why is a girl against the idea of a harem here? I heavily doubt your decision was made on a sexual impulse."
Rika sighed, a smile formed on her lips. "I finally stopped being stubborn and also became a bit selfish."
Arthur furrowed his brows, "You mean..."
"Yes, I have already loved you." Rika looked down, hiding her blushing face from Arthur. She was being quite bashful. Even she didn't expect her heart would be pounding so hard when confessing.
Rika had somewhat liked Arthur even before Shizuka confessed to him. Obviously, the feelings weren't strong. But after Shizuka got into a polygamous relationship with him, she became angry.
Angry with him for being so greedy and offering her best friend a... twisted relationship.
Indeed, her anti-harem idealogy was strong. At first, she had chosen to accept their relationship due to seeing Shizuka so happy, but she just assumed the relationship wouldn't work out.
She had assumed that sooner or later, Shizuka or either Saeko would just break up with him due to one or another reason.
For a few weeks, she even tried to discourage Shizuka from her 'twisted relationship'.
But her assumption turned out wrong...
They were living happily every day. They were content. They made it work. And they did it so effortlessly.
In the corner of her heart, she still didn't like the fact that Shizuka was receiving a divided love, a portion of love from the man she was so fully devoted to.
But at least she finally stopped opposing their relationship, but as she got used to Arthur's presence, she found herself admiring the man. Her dormant feelings began to bubble up again.
But she chose not to be in a relationship with Arthur, for her friend. She chose not to further divide the portion of love Shizuka was getting from Arthur. Besides, unlike in the case of Shizuka, Arthur didn't seem to be romantically interested in her.
So, Rika just chose to treasure her friendship with Arthur.
When Shizuka realized her friend's feelings she even tried to convince Rika to go for Arthur, but Rika rejected her, saying that she couldn't be in a harem.
And when Shizuka went to Arthur so that he could seduce her friend and force her into submission, he rejected her saying, he can't and doesn't want to force anyone into a relationship.
Besides, Arthur wouldn't pursue a woman so against the harem.
Disheartened, eventually Shizuka too gave up.
But after coming to Demon Slayer's world, when even getting a glance of his became difficult for Rika. It became hard for Rika to put a lid on her desires.
Then she understood, that even unknowingly her heart was recieving Arthur's 'divided' affection and it was content with just that, and the absence of it was making it long for it.
And she finally... stopped herself from being so 'stubborn' and decided to be a bit selfish and get a portion of Arthur's love for herself too.
"You wouldn't believe how elated that girl was when I told her my decision a few days ago. And I didn't expect Saeko to be so welcoming of me. Your girls are absolutely lovely." Rika teared up, reminiscing the moment when Shizuka hugged her and jumped in the joy of her friend's selfishness.
"Yeah, of course, Shizuka treasures you the most in the world. After me obviously, with Saeko getting the third spot." Arthur gave a cheeky grin.
"So, um... like... do you want me?" Rika tilted her head, her silky hair fell off the loosely tied bun and some of them draped on her shoulder.
In her red kimono, she looked absolutely gorgeous. But it failed to perfectly hide her ample bosom. Nevertheless, succeeding in entrancing Arthur.
'A task failed successfully, huh.'
Arthur shook his head, "Well, I have liked you too, but as you said, didn't pursue you due to your stubbornness. But now, I don't see the reason to not absolutely destroy the pussy that had made me wait for so long."
Saying so, in a swift motion, Arthur grabbed her from the floor and threw her on the bed.
The clothes on his body instantly disappeared into his inventory.
