The underworld has three levels and in the lowest level there is are two buildings one is a Japanese style house and the other is a modern looking building with a sign near it says 'Chaos '(don't doubt my naming sence) This buildings may seem ordinary but that is far from it ,the material used to build these buildings are bathed in a true dragon's aura for a long time which made it equal to legendary weapon itself the area near the restaurant is a meadaw filled with various legendary plants which are a world tree yaggdrasil with the size of 20 meters under that tree lays a few benches,tables and chairs one side of the field there is a garden in that garden there is various tea plants and rare herbal plants there also are trees with equal importance to yaggdrasil like the apple tree which houses Eden apples ( the forbidden apple) and also the a complete white tree that rediates a claiming effect ( have no name for it) these legendary trees are spread across the medaw with yaggdrasil and the buildings in the middle. There is also a big Sakura tree in the middle of the restaurant since it has a open space ,this is the realm which is smallest and have the highest security in the whole universe because it is the home of the world's strongest dragon and the supreme diety the Void dragon Rimuru Tempest
In the house rimuru can be seen sleeping with Ciel her wife in pyjamas the first wake up is Ciel her cold calculated eyes turned to rimuru and for a brief moment they turned to soft loving gaze

Ciel: no master he birth is set about 2 days from now on
Rimuru: ohh is that so well Ciel do we have plans for the 10 years
Ciel: negative master,all we have to do is opening the restaurant which can be done by a clone without any powers since it is only nessacery for supervision,Veldora and the others can run the restaurant,club like usual and if nessacery we can always tell your subordinates to keep an eye on the restaurant.
Rimuru: that is so ,well Ciel make the preparations for our departure.
Ciel: it shall be done master
Rimuru: all right let's get ready and open up the store,hey Ciel want to take a bath me

No one's POV:
After the two freshen up they went to have breakfast at the dining table there were two people one is blonde man in a white shirt and a black trousers and the other is a black hair with red strikes women her eyes like two rubes while the other has two golden eyes these two are Veldora and Ivaraj , Ivaraj was saved when it was rimuru's turn to check the seal which held her and found that she was trying to fight her own nature to attain reason so Ciel suggests that she should help her attain reason since someone should reward her work so rimuru gave Ivaraj her reason and created some seals so that she can gradually get used to her power since that day she has been living with them.
The two people in the dining room looked at them and greeted them .
Veldora: good morning big sis
Ivaraj: good morning rimuru
Rimuru: good morning you two , wait for a bit and I will make breakfast for us
Ciel: I shall do it master so you can sit with them
Ciel said that and went to the kitchen to cook , rimuru just looked at her moment before shrugging her shoulders and went to sit with the others.
Rimuru: hey you guys me and Ciel are going for a trip to see my student so you guys will be in charge of the shop
Veldora: oh that's rare ,how long do you plan to stay big sis
rimuru: hmm about 10 years since I will stay there for a while
Ivaraj: oh so you shall make choes there
Rimuru: nahh ,I don't need to do that since his soul is like a type S and those people have trouble coming to their door steps every day
Ivaraj: so should we just run the shop like usual
Rimuru: yeah don't worry the chefs will be enough to make the food and I can also have some of subordinates come if we need more staff , the security will be okay since you guys are here
Ivaraj: very well it should be manageable if you out it that way
Veldora: don't worry big sis me and Iva can handle the shop you should just have fun
Rimuru: okay but if you really have any problems just ask me or Ciel using thought communication
Ivaraj: hai hai we'll probably able to manage it without interfering with your journey
As they were chatting Ciel came to the dining room room with food in her hands
Ciel: here is your meals enjoy
they all ate and got ready for their day,the first to leave was rimuru and Ciel they left the house and walked towards the only building that exists in this dimention the restaurant.They opened the doors to the restaurant and went to their respected fields,rimuru went to the kitchen and Ciel went to the garden to pluck the ingredients such as tea,fruits, vegetables and some others well you may ask how do you do this and bring them all ,well the answer is magic ,since Ciel has the best control over magic she was tasked to do this because she can pluck and chose the best fruits without harming the tree
As they were preparing the workers began to come one by one most of the workers are demons, mythical beasts in their human form and lastly the pixies .These people have a minimum power of a arch demons .The demons are the ones who worked for the primordials they come here as to show their loyalty and boredom, the mythical creatures are the one's rimuru crested to guard thier races and since they decendents are doing thier duties they come here to repay thier kindness to thier master and since they are bored,the pixies come here since the spirits rimuru created can't come here because of their duties.
They all came and greeted rimuru and ciel and went to their duties ,after an hour or so the customers began to flood the restaurant .
There are few reasons this restaurant is famous ,firstly the food is heavenly since rimuru and ciel perfected their cooking arts and the other is because rimuru's subordinates come here to relax ,yes this seemly normal restaurant was made by rimuru to give her subordinates a good relaxation since he can't raise any pay since she isn't running tempest so Ciel bevided a plan and that's how the restaurant came to the world
