Upgrading Berserker

"Sakura!?" Kariya walked over with some difficulty as his left leg was barely moving.

Caster looked away from this sorry excuse of a Magus wannabe.

Her mind can't comprehend this guys actions at all, it doesn't help the fact that she is Fae, maybe her Panhuman version would somewhat comprehend as she was more human than Fae, but not her.

"She is fully healed Kariya Matou." He handed over the sleeping girl.

Ren then put his hand on his shoulder and used his True Magic, not long after that the man was healed as well.

"N-No way! What kind of Magecraft is this?" Kariya looked with shock at Caster's Master, he can feel the left side of his face was fully responsive and he can see with that side again!

"Maybe if you studied magecraft you would realised." Ren shook his head, then looked at his hand seal.

"I have held up on my side of the deal Matou, now it's your turn." Magician said that seriously.

"Of course, here!" He practically shoved his hand with seals at him.

"You need to focus on them with the intent of giving them away, otherwise I will need to cut your hand off," Ren said while borderline chuckling at him.

Kariya Matou paled for a second before focusing on his seals which glowed and then put his hand on Ren's commands seals which looked similar to the symbol of infinity with wings.

The next moment his seals glowed and then grew in size the symbols representing wings grew in size doubling, and the symbol of infinity now had a crown on it.

Ren could only smile as he felt a connection to another Servant!

Lancelot, the strongest Knight of Round Table was his now!

"With this, our deal is over, I suggest you leave Fuyuki for several weeks," Ren said as he looked at the command seals before pocketing his hands.

"No need to tell me twice! I will be going to Tokyo with the first flight possible." The Ex-master said with a grin on his face, for the first time he felt free!

Ren nodded and then turned around and was about to leave.

"Oh, right. If you ever go to the place where Matou residence was, do bring swimming gear with you, would you?" He mentioned that off handily.

"Hmm? You turned into some sort of…lake?" He asked with disbelieve.

"I did… leaving the place as an empty hole it would look ugly and people would ask questions. So, turned it into a quite deep lake," Ren said that while walking to quietly waiting Caster, he could feel Berserker following him in spirit form.

"I see… I will keep that in mind…" Kariya has no intention of ever returning to the place, in fact, he still processing the fact his whole family except for Sakura is gone…

"Good, hopefully, we won't be seeing each other again…" With that said Ren with Caster simply disappeared.

…

…

…

"I need to get something to drink…" The now black haired Kariya Matou said while looking at Sakura, he could believe the girl had her original hair colour back as well!

All of this was surreal to him, like some sort of miracle has happened.

~~~~~~Back at Ren's Mansion~~~~~~

"Drawn the circles I need for alteration on Servant's vessel," I ordered my homunculi to start working.

"Master…I am curious… what is your element? I know it's water like mine. But, you have more, correct?" Morgan asked me as she slightly leaned on me.

'This witch! She started doing this more and more!' 

Caster started to get more touchy with time, not that I mind, but each time I need to remember who the hell she is.

While she is not the Black Madonna from Arthurian Myths, she still is Morgan.

"Yeah, it's imaginary elements, Ether and Nothingness," I said with a shrug.

Her mouth slightly opened hearing that. I simply raised my eyebrow and her reaction.

"Same with my origins, its Nothingness and Control." 

This time her eyes went wide, this was the second time I see such a reaction in a single day, it seems my origins has shaken her up.

I would love to ask her why such reaction, but preparing Berserker for tomorrow tops the priority list.

"Anyway, now that you know that, I will return to my work, Berserker needs his upgrades…" I said that while looking at motionless standing Servant.

I could barely control myself and not grin like an idiot after seeing the Servant from Fate Zero.

Each time he manifest I can practically hear his theme song 'The battle is to the strong' ringing in the back of my head.

Now that I think about he needs his Jet Fighter…

Yeah, the Jet Fighter is a must.

"Of course Husband…" Morgan softly said that there was some sweat on her forehead.

"I will empower him as you wished." She said that while looking at the Berserker as well.

"Much appreciated Caster." I thanked her for the help.

"But, of course, husband, I am your… wife, after all."

My eyebrow slightly went up after hearing that, I looked at her for a second. But, she was looking forward and I could not see her face.

Deciding that I can find out this later, I walked towards my homunculi.

~~~

Morgan watched her Master walk towards his homunculi she sighed in relief, thank whatever deity there is that he did not question her that moment.

Learning one's origins is key to learning about a character as it helps one understand about a person.

The witch has learned her master's and that has sent a warning bell to her.

Nothingness is quite a… difficult origin, Morgan can guess it was the reason why Ren completely ignored the fact that she killed a human in Matou house, apart from the bug man.

If she can guess he can just 'feel nothing', a terrifying 'ability' to possess, something even she can end up at receiving end if not careful enough.

Her Master still posses the Command Seals, now six of them…

That moment she looked at the ground for a second, when she was summoned here, her wish for the grail was to return to her Britain and continue her rule. It's a simple wish, something she could accomplish herself with enough prana.

However, it has changed after she heard her Master's wish, he has ignited her long lost ambition, to grow even stronger, to become Queen of the World.

For that, she needs to be around, if her Master gets Third Magic he will reach a new milestone in power, and in turn, he will improve her parameters even more.

The witch thought it will be obvious that he will keep her after the war it's most obvious choice.

But, after learning his Origins…maybe it's her paranoia, but Nothingness… is a very dangerous Origins, and he could just discard her if something unexpected happens.

After all, with Third Magic, the Throne of Heroes will open up for him! And with First he will able to grand powerful vessels to the Servants he call down from the Throne.

'In the end, my Origins is Rule, and I will Rule one way or another.' The pale blonde witch felt excitement and nervousness rushing through her body.

How long has it been when she felt such a multitude of emotions?

'I always get it my way, and husband this will be no different.' Morgan thought about this as she walked towards her Master.

'Now, to make myself indispensable, and unforgettable… I guess I am similar to my human counterpart…'

'What an ugly thought…'

~~~~~~Next Day~~~~~~

The Mediator of the Holy Grail War Risei Kotomine was standing in front of what used to be Matou residence.

The old man was quite perplexed as to what has happened here.

He knew the general location of Berserker Master…

It was nowhere near Matou residence…

So, why a Servant attacked one of the founding houses?

What he saw in front of him was wooden looking walls that are used in construction sites.

It looks like the place is getting renovated…

But, the priest from the holy church knew better, after feeling the amount of prana going through this place he knew a Noble Phantasm has been used here.

He put his hand on his wooden wall, it felt solid, the old man though pushed through and eventually passed through the boundary field.

Next moment his eyes widened what he saw on the other side.

It was a picturesque view of the lake with trees from western Europe!

'Like the legend of the lake, it's like broadcasting that it was done by Vivian or in this case done by its evil counterpart.' 

The old priest is not going to deny the fact that it looks beautiful, even mystical with those greenish-blue particles slightly floating above the water, it looks like the dragonflies.

He looked around more closely and realised that the destruction of Matou house was done in a very… controlled manner, none of the neighbouring houses were touched, even the fences are still in place.

Risei then inspected the boundary field, which had a timer and several set of images which are displayed by the boundary field/illusion.

'This confirms the fact that the Black Madonna is not out of control and moving on her own, no Servant from previous era's would care about secrecy…' 

'That means her master ordered her to do this.' Risei frowned realising what this can mean.

'Is he targeting founding houses?' 

For now, the priest decided to return to the church and report this to Tokiomi Tohsaka.

~~~~~~Evening~~~~~~

Ren looked with a massive grin at his handiwork.

He used his Master's gaze on his new Servant.

"Y-You gave him another class? Is that even possible?" Morgan asked Ren as he told her about the upgrades to the vessel of Berserker.

"Not difficult, after all, they all use homunculi art at the very core, the vessels are not based on human flesh," Ren said with a shrug as he looked at Berserker.

He likes the new greenish-blue particles the Servant emits now, alongside its black miasma, with red colour gone it looked like work of Necromancy of sorts.

The Noble Phantasm was originally at B rank, but now it evolved with Servant's upgraded 'origins', adding simple 'Fae' to its true name can have such effect…

Pity that Arondight didn't fall into the dark side instead it returned to its original look with whole Fae influence.

"If it was that easy Einzberns would give my little sister her Rider and Lancer classes too." Morgan pointed out with an eye roll.

"True. But, then again they are obsessed with their Third Magic nonsense instead of focusing on improving their already existing models." Ren said with distaste, his views on fellow German magus family is not high.

From how they treat their homunculi and to their stupidity with the Third War which caused the summoning of the Avenger Class.

He doesn't like them at all.

"Hoh, so you dislike them then?" She asked curiously.

"In a way, I don't hate them, more like I feel nothing, just a nuisance which should be removed from my way." He casually said.

For a second Caster had the look of realisation, she just witnessed his origins side effect. 

"I see, so we moving at Einzbern today?" She asked barely hiding her hopeful look.

"Indeed! But, first, we need to finish the upgrade." Ren said while commanding Berserker to follow him.

"You are not finished yet?" Morgan asked while could not believing he still has to add something to this monster.

The witch realised with amusement that they are trying to outdo each other with their overkills!

"Nope, I still had to give him his new weapons and of course his Fighter Jet!" Ren said that like a small kid who is going to a candy store!

"What's this fighter jet?" She asked while catching up to him.
