(A/N): This is a really short Omake of how I think the Interaction with all the witches of Sin and Subaru would be like, but I would only make one at a time the first being the interaction of how I plan the relationship between Subaru and the witches.
_______________________
On top of a great mountain, unreachable by man a single teenage boy with inhuman white hair to his back, and dress in nothing but black coating while his eyes were covered in a mysterious face mask.
The boy was just on the highest peak in human history simply sketching the beautiful surroundings for all its glories within the book of truth as he enjoys the beautiful sunset.
Of course, this would look like nothing but someone who enjoy nature for what it is, but honestly speaking there was nothing peaceful about the situation.
Why you ask well it was the boy himself, why you ask, well it was simple he was sitting on the corpse of thousands of silver back Wyners that was stock up like a mountain, so how could the situation be considered as peaceful.
But nonetheless the boy was the one at peace as he began to spoke.
"Interesting."
But as he said this, another voice suddenly rang out from behind him as the mysterious girl voice rang out so loud to the point the mountain began to shake from her words, as she commences throwing a tantrum stomping the ground.
"Ahn why did you kill them; they did nothing wrong."
Subaru being unimpressed by the voice simply replied with.
"For the sake of knowledge and my goal nothing more nothing less."
"But they were trying to survive, couldn't you have least scare them off or som...
But before Minerva could finish speaking, Subaru began speaking something as if directly reading from his book.
"Once upon a time there was a witch name Minerva."
"Oi, don't you dare do that you here me."
Complain the witch as she knew exactly what Subaru was going to do to her, and if he follows true with it there is nothing, she can do about it.
Subaru continues to speak.
"She was one of the servants of the strongest person in the world, but because she and the other lost their authorities upon dying they became less useful and seek help from said person who help them rebirthed in the world a new."
Subaru continue to read while Minerva continues her rambling.
"Hey answer me at least help the injured one that are still alive there is no need to go to such extremes right."
Meanwhile Subaru continue reading without paying Minerva any mine at all almost as if she was an insignificant ant.
"Life continue the same for Minerva and the other witches till one day Subaru ask her to come to another world with him in order to get the material needed to commence project redivivus as her artificial authority can still be useful to him for such a dangerous world like this."
"Stop it I still didn't say good bye to my new friend here, you're making me angry."
Shout Minerva who was punching Subaru consistently in rage but it did nothing to him as the artificial authority he created for the witches were almost the same power they had originally but with slightly different effects.
If anything, Subaru felt stronger, but he continues to read the word in the book of truth slowly as a way to bring fear and tear in Minerva eyes for disturbing his peace.
"Out of excitement Minerva and the other witches began to drank a whole lot of snake wine the night before they leave to the other world, sadly for Minerva though she overdrank giving her the worst hangover one could ever feel the next day, causing her to stay behind."
"Sob... your so mean."
Minerva began to cry because it was already too late, and the next word she spoke was.
"I swear I'm going to get you back for t...
But before she could even finish saying what she wanted to say she suddenly disappear while some injuries started to manifest on Subaru body and his stamina dwindled a lot, but the dragon remain dead and all this was caused by Subaru simply saying.
"The end."
After that the peace and quiet return once more as Subaru said.
"Agh... finally, some silent; I swear she could be extremely annoying when someone is injured."
But as Subaru said this, the sword on his side began to talk as an all too familiar voice spoke.
"The girl was annoying, I myself would have done what you did as well, it I was in your situation."
"Haha truly I feel sometimes you're the only one that gets me partner, although I must say Echidna is kind of tolerable be around with sometime as well."
The sword simple did a slow laugh and spoke.
"Hahah...the same goes for you as well partner, after all, both of us have the same goal, but I also must say that your authority of sloth is getting better and better, the fear on her face was indeed satisfactory I hope she learns from it though."
Subaru smiled at this and spoke.
"Weren't you the one that thought me that fear is necessary for evolution."
"A quick learner as always but remember were focusing only on the authority of sloth for now since it the key to solve our greatest problem."
"Indeed, it is but can we really finish project redivivus before the sword saint and the worlds other counter guardian catch up to our plans."
"In time partner, you just have to have patience, and train more with the authority of sloth, after all, if one abandons all other abilities and focuses his strength entirely on a single specialized skill, then he can overcome even the greatest of powers, this is saying that I still believed to this very day."
Subaru smile honestly once again as he spoke.
"Well, I will trust your judgment partner we still have a lot to do if we want to achieve perfection, so I think I will wrap this up and go the next location."
"Very well then I believed we need the third eye from the menace of the black woods."
"Yes, he going to be a pain in the ass his level was 435 and that just his base form before his Hp reach 30% and go into a berserk mode making him a level 500, I honestly hate legendary boss monsters but the reward will be fitting for king like myself."
"We have return by death so things will go our way regardless."
From their Subaru look at all the dead Wyners as he opens up the book of truth and spoke.
"All before me shall melt into product of evocation, and return to thy tome and join the chronicle of truth."
And as he said those words all the Wyner melt into weird black substance and transform to literal words and all those words suddenly fly straight into to the book of truth leaving nothing behind.
--Close--
Subaru close the book shortly after he melt all the Wyner to products of evocation.
From there he then jumps off the high cliff to go the black wood to acquire yet another ingrediencies, as his last word were.
"I will accomplish my goal no matter the cost."
