A certain platinum blue haired individual, with golden eyes that could seemingly see through everything, was sitting at his desk, going through his paperwork. His pale skin and aura he gave off made him look like a deity, which suited him well, just like the black coat and fur that he wore. He sighed.

"It has been 10 years since Yuuki was defeated, 10 years since I saved the world… 10 years since I resurrected my other self, before I died and reincarnated here. So as the savior of the world, the thanks I get in return is a BUNCH OF PAPERWORK! REALLY?!"

His name was Rimuru Tempest, known as the Great Demon Lord who saved the world, the Lord of the Jura Forest, the King of Monsters, and member of the 8 Star Demon Lords (or Octagram).

And he was bored. After saving the world, his schedule became monotonous. He would work on paperwork from sunrise to sunset, occasionally even after sunset, before heading to bed. He would participate in meetings, which were once about reconstruction of infrastructure after the war, but slowly turned to simply checkups and reports.

He could give all the paperwork to Ciel, the conscious being that evolved from one of his Ultimate Skills, and let her do everything, but according to her, he was avoiding responsibility, and scolded him.

He remembered what Ciel had told him when he asked her to take care of his paperwork.

["Hmph. It is your country Master, and thus both your responsibility and problem. I love you, but you need to take responsibility."]

"Sheesh, give me a break here…" he thought.

He would occasionally slip out and have some fun with some of his subordinates, but would eventually get caught and punished by Shuna or Shion, whoever caught him first.

In other words, he wanted to do something fun for a change… for longer than just one night.

He decided to quickly check if his other self was doing ok. After all, the both of them were stuck in their offices working on paperwork most of the time, so they could relate. They were technically the same person, after all.

He attempted to locate the soul of his other self. Surprisingly, he could not locate it.

Rimuru stood up. Something was not right.

"Ciel, can you locate my other self?" he asked.

["...negative...unable to locate him. It seems that something has gone wrong…"]

It wasn't just him. Even Ciel couldn't find his other self. Ciel's voice was also filled with worry.

He immediately called for Shuna. As she arrived, she could immediately tell that something was amiss.

"My lord?" she asked.

"Shuna, notify the 12 Patrons and Souei. Tell them to meet me in the Labyrinth, 100th floor."

"Understood… Is something bothering you, my lord?"

"Yes, you know how ten years ago I made a parallel self in my original world?"

"Yes."

"Well, I can no longer sense him. That means he is either dead, which I should have sensed, or something happened. So I'm going to take a look." Rimuru stated this vehemently.

"U-Understood, my lord."

Shuna took one look at their Lord. The person that they owed so much to, the one they had sworn loyalty to, and the one they loved and respected above all else. She recognized the look on his face. That look was the same look that he had when Shion was killed, back before he became a demon lord. The face of someone who was angry and upset. She also knew that she would not be able to stop him.

"Please be careful my lord, and please bring someone with you as well." she said, before leaving the room.

Rimuru took her words into consideration, before immediately teleporting to the 100th floor of the Labyrinth.

A few seconds later, a certain annoying lizard showed up. He had tan skin, light blond hair, and was bare-chested. This man was someone who had caused him headaches on a daily basis. However, unlike the usual, happy go lucky and casual Veldora, he was instead greeted with incredible seriousness.

"So Rimuru, where are you going?" asked Veldora.

"Remember when I went to the otherworld and made a parallel self? I can't sense him anymore and it's making me worried, so I'm going there to check it out. Before you ask, no, I do not wish to bring you along. This is my business, and my responsibility."

["Master, It would be wise to bring someone else, just in case…"]

"I know Ciel, but it's just… I don't want to wrap anyone else in this, despite their desire to."

A movement caught Rimuru's eye, he turned away from Veldora. In front of him were fifteen individuals, all kneeling, except one. He scanned them from left to right.

Shuna.

A red-haired man with a pair of horns on his head, wearing a red uniform and a large Katana at his belt. Flare Lord Benimaru.

A blue-haired man with a single hord on his head, wearing what looked like a ninja outfit. Intelligence Officer Souei.

A large canine with a pair of yellow horns on his head. The figure of a wolf, with sleek dark grey and white fur, with a star on his forehead. Star Lord Ranga.

A dragonoid, with purple scales and a blue trident in his hands. Dragon Lord Gabiru.

An orc, with black clothes and a white shirt, clearly coming from a construction site. Barrier Lord Geld.

A purple-haired lady with rather large breasts and wearing a purple suit. First Secretary and War Lord, Shion.

A black haired man, with streaks of red flowing through it. His eyes gave off no warmth whatsoever, instead, his flashing yellow irises gave off a feel of omnipotence. Second Secretary and Demon Lord, Diablo.

Another lady, with 9 tails and silver and gold hair. Chimeric Lord Kurama.

An individual clad in a black exoskeleton. He was Mist Lord Zegion.

A skeleton in an extremely fancy robe, fit for a King. Gehenna Lord Aldaman.

A trio of women. One with white hair, one with purple hair, and one with yellow hair. Killer Lord Testarossa, Pain Lord Ultima and Menace Lord Carrera respectively.

And finally, to his surprise, a lady with black hair and dark navy blue irises. She had a burn scar on her left eye. She had a Katana at her side, wore black leggings and a white shirt. Shizue Izawa, the Conqueror of Flammes. His "Soulmate", though he could think of many people who would disagree with that statement. (Milim, Ramris, Chloe, Shion, Shuna, and of course, Ciel).

["The guesswork of a fortune teller is nothing compared to my calculations, Master. And I am telling you that She. Will. Not. Be. Your. Wife!"]

"Yup, classic Ciel. She was even more pissed off after we revived her from the dream dimension within me. Back at the final battle, she asked for Ciel to let her speak with Yuuki, while we were fighting. Surprisingly, Ciel refused, but then we later managed to swallow Yuuki up into {Void God Azathoth}. One talk later, and we were all friends again. I even managed to seal Yuuki's deranged personality away, leaving the manga loving and honest but somewhat manipulative side of him left. Of course, after Yuuki was released, Shizue asked me personally if it was possible for her to come back. She said it was because she missed the kids, and wanted to see them grow in person. Another reason was because although she wanted to die as a human, seeing me work so hard to create my ideal and my utopia, all while saving the world and doing what she could not, inspired her to keep living. So, with the help of a reluctant Ciel, we revived her as a demigod, the same race as Leon. I think she may be able to give some of the 12 Patrons a run for their money, hell, she did beat Leon to a pulp after she was resurrected. Leon didn't fight back though, but maybe that was because Chloe was cheering for Shizue and not him. I felt really bad for Leon. On another note, she is also connected to me through a Soul Corridor, and could return to the dream dimension whenever she wanted. But she didn't. I'm still not quite sure, does it have to do with the whole "Soulmate" thing?"

["NeGatiVE! You are imagining things again Master!"]

"Maybe I am...But Ciel, are you jealous?"

[" … … … … "]

"So you don't deny it."

["Master, do me a favour and SHUT UP!"]

"Yup, Ciel is definitely jealous. And she has DEFINITELY gotten sassier."

Rimuru, caught in his thoughts, didn't seem to realise that his subordinates were getting restless. However, he then broke out of his trance, as he was wondering why Shizue was here.

"Shizue, why are you here? I don't remember asking to meet with you."

Shizue then smiled, before responding.

"I saw Miss Shuna running and contacting others through {Thought Communication}, and it had something to do with an abrupt summoning. What's more, I did feel your aura fluctuate a bit, so I got curious, Rimuru-san." she said with a shy smile.

She had started calling him Rimuru-san once she got revived, though she occasionally still called him Slime-san.

Rimuru nodded, before turning to the remaining 14 individuals.

"I'll be leaving shortly for the otherworld. You know, my original world."

Immediately, everyone excluding Veldora, Shizue and Shuna stared at him with wide eyes. Rimuru wondered why they were staring at him like that, until Diablo and Shion started speaking nonsense.

"My Lord, Please tell me how I have failed you! I will fix this error personally, I humbly request another chance!" said Diablo.

"MY LORD!" yelled Shion, tears flowing down her face. "If there is anything we can do to make you reconsider, PLEASE TELL US!"

"HEY HEY HEY I'm not leaving permanently, why are they all looking at me depressed like that?!"

"No No No No let me explain-" started Rimuru, only to be interrupted by Souei, who, looking depressed, turned right around and started to slowly sink into his shadow.

"SOUEI STOP! I have a REALLY important task for all of you while I am away. This is TEMPORARY!"
