A whole new world

"Haah, we finally finished, did curses went extinct? We had to search for few months to find at least 4 of them." Sukuna sighed in annoyance. He will make sure to destroy good part of all sorcerers in Japan. He doesn't need to kill all of them though, because it will be of no need. They will most likely cease to exist anyway, because of other factions. He then yelled: " Hey, Tamamo! Are you ready?! Does it take so much time to get ready?!"

"Wait a bit, will you?" came a shout from other side. They were currently near ocean, as they were getting ready to leave. Sukuna can't really understand what she needs to take with herself. She should have magic, so what can even malke her so long to get ready?

Minute later she finally came back. One would think that nothing has changed and it really was so. Only thing Sukuna noticed was her different hair style. If before she had 2 ponytails on the side, then now she had all her hair behind.

"Did it take so long to just untie 2 ponytails?" Sukuna asked in disbelief, he thought that she did something more important, but it seems like he had too high hopes.

"Oi! Don't give me that look! I had to think about my hairstyle. We are going to a new place, so I had to look even better than I usually do!" she yelled in joking matter and then asked: "So, Sukuna-kun, how do I look?~" a hint of anticipation was heard in her voice.

'I definitely had set my hopes too high for her' he thought as he heard what she said. He then answered to her question: "You were looking good before as well, so I don't see any point in changing your hairstyle for 15 minutes straight. Anyways, if you are ready, can we leave?" he completely ignored how she called him. He got so used to it, that it became something completely normal for him.

"Hmm? Really? I guess it's fine then." she was happy with that answer that she got. As far as she knew him, he doesn't tend to praise someone, especially for something as irrelevant as looks. And even if he does praise someone, then he does it in a mocking manner. Tamamo then said: "But yeah, we can leave." as she said that, they both teleported away.

Somewhere in the ancient China, forest.

Two people, man and woman, manifested from seemingly nowhere. They were in a normal forest or it would look like one, if not for the energy fluctuations that they sensed in the distance.

"Hmm? What is this energy type? It's not life force nor it is spirit energy. It resembles a cursed energy a bit because it has some negative emotions, but it's far weaker and entirely different as well. Do you know what is it, Tamamo?" Sukuna asked, they haven't even properly arrived and they have already something interesting here.

"No.. I don't think I know.. should we get closer?" she asked.

"Of course, we have to get closer, it is something entirely new. And it doesn't seem to be so powerful. In fact, whoever uses this energy, seems to be even weaker than a decent curse, so we will be completely fine."

When they got closer to where the energy came from, they saw a barrier, 2 to be exact. Albeit they were really weak. Maximum that defensive barrier could do was to block animals and the illusion barrier would hide this place only from average human. When they saw it, they went through barriers without any problem. When they got inside a barrier, they saw a medium size house.

As they stepped in the house, they noticed a man of average height. He had black hair and brown eyes. When the man saw 2 intruders, he tensed up. If they got in, then it means that they aren't normal humans. But when he saw that one of them was a woman and an outstanding beauty as well, his eyes were instantly filled with lust.

"Huh, so this is our extraordinary individual.. he clearly looks like a human, albeit he is not. But that energy.. hey, you." Sukuna asked the man in front of him, which brought latter out of his thoughts: "What are you?"

But the guy seemed to completely ignore Sukunas question. "Hey, man. Maybe you will give that girl to me? You can leave then freely, I won't even do anything to you." as he said that, he unleashed his measly aura. He already forgot that those in front of him aren't normal humans either. His only thoughts were to have fun with this beauty in front of him.

"Huh? I asked you a question, trash. Don't think that you are all mighty if you can possibly kill some weaklings." as Sukuna said that, he used his two fingers to slash towards an idiot in front of him. Not even second passed and a man in front of him lost all his limbs.

"What? My han-n-ds.. what did you do?!" man screamed, as fear and hatred filled his voice. A moment ago he was standingn with all limbs intact and now he is lying on a floor like a potato bag. He didn't even notice how he lost his arms and legs in the first place.

"Shut up, you are already too annoying to deal with. If not for you being at least a bit useful, you would be dead already. Answer few of my questions and I will kill you painlessly. I'm in a good mood today, as I will finally find something amusing to do, at least I hope that I will." he said that with a excitement written all over his face. He doesn't have time to play with this sorry excuse of a living being in beneath him.

"F-fuck you! I won't say anything to you!" the man yelled in frustration, he couldn't really do anything at this point though.

"Hmm? Is that so? Seems like I have to get my hands dirty. Let's start, shall we?" he said it with sadistic smile on his face. He wonders for how long he will keep up till he breaks.

And thus, started a long session of torturing and interrogation.

"So he is apparently a devil huh? Pretty interesting, I guess they mostly hide in Underworld, that's why we haven't met them. Hey Tamamo, did you get something from that teleportation circle in the living room? He said that it will take us directly to Underworld." Sukuna got a lot of information from that one. He said that he was researching something here, but it isn't so important right now. He thinks that this Underworld will be more entertaining than some researches of weakling.

"Yeah, I got some coordinates and I can say that it is in another realm, so him lying is highly unlikely. By the way, this energy of theirs, what was it called?.. Demonic power, I guess? It's really convenient I must say, they can even use teleportation circles with ease. It resembles my energy type. Even you could possibly use it, if you had it." she said with a sad smile. She can use her own magic to teleport and do other various stuff, but Sukunas cursed energy can't do such feats.

"Hmm.. so even such weaklings can use teleportation? That's really interesting. Though I'm sure that there is another way to use magic.. Anyway, can you teleport us to the Underworld?" he could think about that later, but he must say, that it's really convenient even if mid-class devil could use it. Yeah, that devil was apparently a mid-class devil. He said that there were 6 classes: low-, mid-, high, ultimate-, satan- and super-class devils. He also stated that there were millions of low- and mid-class devils in Underworld. But there weren't many of others classes, especially those that were ultimate-classes and higher, if compared to low- and mid-class devils. He said that the strongest one there should be some guy named Lucifer; Father of Devils. He, alongside with Leviathan, Beelzebub and Asmodeus rule over the Underworld.

Lucifer also has a son, Rizevim Livan Lucifer. He was said to have more potential than his father himself and that he should be able to reach super-class in near future. Devils theorize, that super-class devil could easily fight against gods, so that ought to be interesting trip there. But there were also other existences like fallen angels and dragons. Of course there were more beings out there, but most of them were low or non intelligent ones.

"Of course I can! Who do you take me for? Anyway, they have some defensive barriers there, to block not authorized beings teleportation, but we can bypass them easily." as she said that, she snapped her fingers and they teleported away.

Somewhere in Underworld.

Sukuna and Tamamo found themselves in a small hut. There was nothing notable in it, just a teleportation circle under their feet and a door in front of them.

When they got outside they saw a purple sky. It was impossible to tell if it was a day or night right now as there was no sun nor moon, but it didn't bother them in the slightest.

They found themselves in the middle of plains, while the hut was hidden between few tall woods that were here. In the distance they saw a rather huge city, that looks nothing like ones back in Japan. It had enormous wall around it, few tall towers around they city and a magnificent palace in the middle. That's all they could see, because the wall was blocking their view.

"It certainly was worth torturing this little devil, just look at this view.. I wonder how much interesting stuff we could find here.. I also can feel few powerful presences nearby, even though they aren't as strong as gods are, but they definetly are much stronger than those annoying sorcers. It certainly will be a fun trip!" Sukuna said with a excited yet sadistic smile on his face.

"Sukuna-kun.. Maybe we should first look around? It's not like I'm telling you what to do but.. we might miss something if half of Underworld will hunt after us. And who knows, maybe they have someone stronger than us to send?" she said with concern in her voice. She knows that Sukuna is strong and not many could even scratch him, but there might be some stronger existences here.

"Of course I know that there might be someone stronger than us, but isn't it more thrilling this way? And if situation will be really dire we could use some of our trump cards. Also, as far as I know, devils are extremely arrogant, so they most likely won't send anyone strong to hunt us down. But sure, we can be a bit more cautious here." he stopped for a moment before he looked at her. He then sighed and said: "So.. where do you want to go? It will be my thanks for pushing me out of Japan. Of course I would eventually travel around the world, but who knows how many interesting events I could possibly miss here."

"H-huh?" Tamamo startled a bit, her mind almost went blank. She never thought that Sukuna will say something like this. But she didn't think much about it. Her mood immediately skyrocketed and a smirk formed on her lips: "When did you become so kind-hearted?~ Maybe you are starting to.. like me?~" she said last sentence in a teasing manner.

"Shut it. Choose faster or we will go on yet another massacring and then you won't be able to see anything but blood of rivers and mountains of skulls. I know that you are a bit sadistic, but even you don't like to see it." he said it as a matter of fact. She sometimes likes to play with humans and alike, but she mostly does something productive or interesting. And right now they are in totally different realm, so she will rather explore it rather than killing poor devils left and right.

"Mou~, must you be so cruel? Let's go to the city, there should be something that we could find useful, also we could collect some information. That guy said that people devils with 4 arms do exist here, so it won't be a problem. And I can hide my ears and tail with illusions, so that isn't a problem either." she said with a wide smile.

"Sure.. but I would like to go to this forest there later." he pointed at a creepy forest that was like 10 kilometres away: "I can feel that someone strong resides there and that thing has completely different aura from devils." with those last words said, they went to the city in front of them. They both were anticipating about this whole new world.

(A/N: As you can see they went to the Underworld. I already have few ideas about what I should write while they are here, but you always can give me more ideas. Also, I wrote that cursed energy techniques can't use teleportation, prove me if I'm wrong. Of course there are some techniques that can manipulate space to some extent, but Sukuna mostly specializes in slashing and destryoing.)
