Rimuru's Return

Chapter 1 : What Happened

Before the chapter starts let me sum up what happened before Rimuru left the tensura verse...
_________________________________________

After 21,427 years since the Great Tenma War the world has been peaceful and under the protection of the Great Demon Lord Rimuru but as time passes the more bored Rimuru got bored, cause most times almost everyday he'd spent signing paperworks and he wanted to fight or have a match he hasn't fought with anyone for a long time cause there was no one in the whole multiverse could take his power head on, at first he could still fight with individuals that you can count just by your fingers but times go by and we all know that every single day Rimuru got stronger

And so after those years there was no one that could take him and so he decided to pick a student to be his successor, it was Minavenia Chandiel an elf child, she had beautiful blonde with green ombre on the ends and light orange eyes and a tanned skin

Rimuru saw a bright beautiful potential in Minavenia and took her as his student in secret, she was being raised and  teached by Rimuru for her to be the future Queen (or rather Monarch if Minavenia wanted to rule by herself)of The Great Jura Forest and Jura Tempest Federation

Rimuru loved Minavenia like his actual child, he protected her but also let her managed the situation if he knew that she could take it, after teaching Minavenia his knowledge and techniques and the ways of things he knows, he bestowed her with gifts and even created 2 Ultimate Skills for her first was [ Night Goddess Nyx ] the skill was part of what Rimuru called Greek Mythology Skill Series

And the other was  [ Spear God Ansgar ]
After she was gifted Rimuru told her that "3 days from now, I'll be introducing you to my subordinates, and two weeks from that you will be given etiquette lessons and then after 4 weeks from that you will be crowned as Queen of Tempest." Rimuru said, the girl asked if she will see Rimuru again but Rimuru could only say "you will, maybe if you waited a million years, well you do have longe-" but Rimuru couldn't continue cause the child hugged him and pleaded for him to stay but he explained that he needed to leave because

Rimuru wasn't just leaving Tensura Verse cause he is bored it's also because of the incoming trouble from the mega verse a better version of the multiverse cause it consist infinite number of multiverses that's why Rimuru shall travel to get strong and protect them from the great danger and also conquer or be the strongest among those infinite number of multiverse, he needed to do that so he can go to the next level which is mega verse

He of course didn't explain that to the child cause it was way too much for a mere child to handle (P.S. the child is 16 years old and elves live a very long time so that kind of age is considered very young, but she can transform into a 16 year old appearance so she can keep up her trainings with Rimuru) He only caressed her head and kissed her forehead and covered her with blanket and left the Imaginary Space (Yes they were there the whole time)

And did more paperwork.

After 2 months had passed it was finally time for the coronation "I'm nervous Papa!" Minavenia said squeezing Rimuru's hand, she was wearing her own custom made queenly (?) outfit (it looks more princessesy)
