"Servant, Caster.Now which one of you fools summoned me?"

Chapter 1:Round 1

The man, who had a smile on his face, seemed to be in quite a good mood. Perhaps he was happy at being summoned...though that did little for the threatening aura he was giving off.

Deciding to step up, and ignore the fact they were all just called fools, Ritsuka gave an akward smile while pointing a finger at herself.

"...T-that would be me."

Standing up and stepping down off the shield, the man took a few steps towards them, causing all of them, even Mash to jump back in fear. The fact he didn't even flinch at their reaction was not comforting.

"I see, then consider yourself lucky, I am currently in a great mood, so..." he stopped to take a glance at Olga Marie and Mash, and then his eyes went back to Ritsuka before his smile turned into a smirk "Sheesh only women? well it doesn't really matter.Now, hurry up and make a choice, I've got quite a lot of stuff to do."

Confused at her new 'Servant's' strange behavior, Ritsuka's expression turned into a frown.

"Uh- sorry but I don't think I understand, what do you mean by 'make a choice'?"

While Ritsuka and the strange man were having a conversation, Mash was staring daggers at him, her instincts yelling at her that this..."thing" was pure evil.

"Jeez, do I really have to spell it out for you" with the same mocking tone of voice he said the following words as if there was nothing wrong with them "I am telling you to pick which one of them" taking a moment to point at her two companions "...will die first"

"w-what do you mean by tha-"

"HEY YOU!"

Looking towards the source of the sudden call out, Ritsuka found her boss, Olga Marie Animusphere, glaring straight at the man who just threatened to kill them. Her behavior could be defined as courageous...if you ignore the fact she's currently hiding behind Mash like she was using her as a shield while also trembling.

"W-we are Chaldea Security Organisation, we are the ones who summoned you and also supplying you with magical energy, so don't think you can get away with-"

The pink haired man, who now had his attention on the women trying her best to threaten him, was completely ignoring whatever she was saying as he eyed her curiously with a hand on his shin, it's almost like for him...there was something 'wrong' with her.

Suddenly his eyes widened a bit, as if he just had a realization, which for some reason made him look a bit disappointed.

Olga Marie didn't fail to notice this as she stops her threats to look at the man with a confused expression.

"Hah? Seriously? Well that kind of ruins the fun, there's no point if I am not the one who did it. Eh like they say 'what can you do?'"

Finishing his sentence with a shrug, he regains his mocking smile and looks back at Ritsuka who was confused on why he suddenly looked demotivated.

"You really are unlucky...what was the word again? Ah yes 'Master'" his voice somehow getting even more mocking at that last part "Not only did you summon me of all people, but now you're going to get killed without even being able to decide which one of your friends dies first, you know, back in my era people would think somebody placed a curse upon you or something...well I guess it is pretty accurate, honestly I might just pity you."

Finally realizing the servant they summoned is out for their life, the Chaldean party of three members all put their guard up, Mash quickly moved to the front of the group, Olga Marie started pointing a finger gun towards him, and Ritsuka put a hand on the wrist of the arm with her command spells to show she is ready to use them.

The man looks at them with the same arrogant smile and demeanor he had ever since he was summoned and lets out a small chuckle, as if the fact they wish to stand against him amuses him.

"Good, good. Humans should struggle till the very end, it's what makes them entertaining after all." setting his sights on Mash he speaks in a slightly lower tone "Since I've already decided I am leaving the one who summoned me for later, and it would be no fun to kill the white haired one, guess you will be dying first." he took a moment to raise his arm forward with his hand half opened "I already wasted more time than you actually deserve so I am just gonna make this short, I am going to kill you...for no particular reason"(I didn't want to use any jjk lines but damn I needed to add this one)

Pulling his index finger up, he quickly swiped it sideways. Mash feeling like an attack was incoming, quickly shielded herself by putting her hands up in a X shape, this quick reflex might have being the only reason she was still alive since the man was directly aiming at her neck. She felt something sharp, like a sword slash, except without the sword itself, hit her armored forearms, causing her to quickly open her arms to split the attack into two, and giving 2 big scars to some of the buildings behind her. She then started glaring at the man infront of her, who seemed to be a bit confused on how she survived his attack.

"A Servant...?"

Suddenly the man's mouth turned into a massive smile, showcasing his white canine teeth in all their glory, and all 4 of his eyes started staring at Mash with what can only be described as pure bloodlust, his black tattoos only made his demonic face even more sinister. And for the first time, Ritsuka felt true fear, the arrogant aura the man exuded in the beginning was nothing compared to the intensity of his current state, and that face of his...she could only describe it as "the joy of a predator finding a prey to torment".

Olga Marie wasn't doing much better, infact she was completely frozen, as if even trying to move would cost her life. Mash however, despite being the target of his fierceness , only tensed for a bit, and then put her hands up with her fists clenched to show she is ready, perhaps it was the Heroic Spirit inside of her that helped her stay calm.

After a bit, the man's expression relaxed a bit, though it was clear he was now much more serious than at first.

"Interesting...I was gonna give you the honor of toying around a bit before killing you, while keeping the orange haired alive till I find a reliable supply of energy but guess I have to change my plans for a bit."

Ritsuka didn't really appreciate being treated as living battery that was going to be disposed of sooner or later, but she knew better than to voice her concerns.

"Oi, pink brat" Mash didn't flinch at being called 'pink brat', but glared at the man even harder. "Come, or I'll kill your Master".

Instead of listening to him, she turned around a bit to look at her Master. Understanding what she was waiting for, she gave her the order.

"Mash...Go!"

Following her Master's command, Mash sprinted towards the man with a fist raused up and jumped to punch him. He simply avoided the attack by moving to the sides with a smile on his face, this seemed to be part of Mash's plan, as the second she landed on both her feet, she picked up her shield and instantly swung it at the man who had her back turned on her.

As if he had eyes on his back, he crouched down before the attack could hit him and then without turning around, he rotated his wrist towards Mash and flicked both his index and middle finger. Realizing she couldn't dodge the incoming attack, Mash braced herself for the pain but it never came, since she did feel 2 invisible slashes hitting her body, but they didn't cut through it and only pushed her back a bit, the man who turned his head around a bit also seemed a bit surprised at the lack of blood, but didn't have time to question as Mash was bringing her shield down at him, he jumped up and landed next to Ritsuka and Olga causing them both to stop moving and look at him with fear in their eyes, then turned around to look at the ground destroyed where he once stood and Mash standing with the lower part of her shield on the newly created small crator.

Mash, moved her shield to the side, only to realize that she made a fatal mistake as she saw the Caster was now in close proximity to her Master and director, with a worried look in her eyes she stared at the servant to gauge his intentions. Fortunately, the man seemed completely uninterested with the other two, instead he was staring at Mash with a somewhat curious expression, he also had his fingers on his chin again, showing that he was thinking about something.

'Doesn't seem to be pure natural toughness, perhaps a resistance of some kind... interesting, this will be more entertaining than I thought'

His smile had now returned, he turns his head a bit so glance at Olga Marie, who stiffened at his glare.

"Scram"

At first she was confused on why the Servant would let her get away so easily, but didn't question it as she quickly grabbed Ritsuka and started running away from the battlefield by following the road.

Ritsuka, at first, didn't resist as she seemed to be still shocked at the events that just happened, but after a bit she realized they were leaving Mash behind, with a worried expression she looked at the back of her director who was holding her hand while running

"W-wait, what about Mash?"

"We have no choice, she'll have to hold him off while we escape" though her words seemed to be cold, her expression showed deep frustration.

They then take a turn left as the road, covered in destroyed vehicules,started to curve.

"Can't we help her? I am his Master so I can just order him to sto-"

"That's why we're running away idiot! If you tried use your command spells in close distance to him, he would kill you in less than a second with whatever that invisible attack of his is!"

Olga Marie then suddenly stopped, almost causing Ritsuka to almost trip and fall, she looked around for any sign of being watched, then let out a sigh.

"Alright, we should be far enough. Now use your command seals to order Caster to stop stop attacking"

"... Wouldn't it be better if I just ordered him to die"

"We wasted a lot of magical energy summoning him, so its worth trying to get him to join us then getting rid of him, plus even if he refuses Mash should be able to kill him."

Ritsuka didn't really think the man would ever agree to work with them considering what she's seen from him but decided to go along with her director's plan so with a shrug she raised her hand up and looked at her command seals.

"Caster, I order you t-"

Suddenly, they heard the sound of an explosion behind them, turning around they saw Mash, right at the curve of the road. She seemed to have collided with the building behind her considering the cracks on it, fortunately she seemed unharmed as the only difference between when they last saw her was the fact she was now covered in dust in some places.

Mash seemed to have noticed them, as she turned around to look at them, she was about to say something but stopped when her eyes caught the massive projectile hurling towards her, quickly ducking she narrowly avoided getting her neck crushed by her own shield, as it was now on top of her, stuck in the building, without wasting any time she grabbed her shield and put it in front of her to block the incoming attacks. Suddenly multiple clangs could be heard from the shield, it was the same invisible slashes they saw before, the only difference was that now they were being fired at a rate that could be compared to a minigun, and while the shield and Mash were unharmed, if only pushed back a bit, the same cannot be said about the building behind them, that collapsed from the onslaught of slashes, causing Mash to be burried under rubble.

.

.

A few minutes earlier.

Mash couldn't help but let out a breath of relief when she saw her Master and the director fleeing from the battle, but she still wasn't distracted as she eyed the man in front of her.

'Senpai should be able to stop him with her command seals, meaning I should just focus on holding him off'

Steeling her resolve, she put her shield up to cover half of her body and waited for the man to make a move, primarily focusing on his fingers, she didn't know if it was because he noticed her warriness or something else but the man let out a chuckle

Suddenly her vision went black for a split second and she felt her head being thrown back a bit, one of the slashes had hit her right in the eyes.

'but how?! he didn't move his hands! unles-'

Her thoughts were interrupted by a voice behind her.

"A common trick I used in my time, though few actually were able to witness it."

On instinct, she swung her shield a full 180 degrees to hit the one behind her, however in the middle of the swing she felt multiple slashes hitting her arms,chest and head causing her to delay her swing and hit nothing but air, however it did allow her to put her shield Infront of her and this time covering her whole body, and even though she couldn't see him she knew the man was still Infront of her which was confirmed when she heard his voice.

"you know...you're pretty strange"

Suddenly she felt thousands of forces hitting her shield, causing multiple loud clangs to be heard, yet somehow the man's words could still be heard clearly.

"You have the reflex and instinct of a veteran warrior...but your mind is that of a sheltered brat"

She couldn't help but grit her teeth at the "sheltered brat" part.

"Its almost like..."

The barrage of attacks stopped, causing her to frown in confusion, the confusion quickly left when she felt a new force on the right side of her shield, turning around in panic, her worse fears were confirmed when she saw a hand griping her shield, and the face of the man slowly creeping into her view with the same arrogant smirk of before.

"the abilities you posses are not yours."

Before she could even react, she felt multiple invisible slashes hit her body, pushing her back and causing her to let go of her shield, she tried grabbing it again but the man quickly threw it aside, and then grabbed her leg.

"Though its disappointing you turned out to be just a brat with powers you can't even use properly..."

Using her leg, he threw her whole body to the sky, her reflexes quickly helped her turn her body around to face the ground, and try to dropkick the man.

"How about you help me get used to my powers..."

Suddenly his arms were covered in a strange blue aura while the distance between him and the falling girl was drawing closer, when they were about to collide, he quickly stepped to the side, dodging the kick and then grabbing her leg once again.

"...with a quick little strength test!"

With a grin on his face, he spun the girl around 180 degrees, then with all his strength threw her towards the road her friends just used, causing her to fly towards a building, ricocheting off the ground twice before smashing into it.

With a casual expression, the man looked at his arm as if analysing it, completely ignorong the fact he just threw a person like a ragdoll.

"...Not bad considering the "Caster" class is meant to be the weakest physically, though its not comparable to the time when I was alive."

He then looked towards the shield he threw aside and smiled.

"Well just to be sure, why not double check?"

.

.

Present time.

Ritsuka didn't know how to react when she saw her junior just get buried in rubble, fortunately or unfortunately she didn't have time to, as her attention quickly turned to the sound of footsteps coming from the side of the road Mash came from, coming out of it was the man, with an unimpressed expression.

"Oi you gonna come out yet, you may be a brat but you're still a Servant, so this rubble shouldn't even scratch you, unless this is your sorry excuse of an attempt at a surprise attack."

After a few seconds of tense silence, that felt like months to Ritsuka and Olga, Mash came out of the rubble in a split second with her shield up, which earned a smile from the man.

"Good, can't have such a good punching bag break to quick-."

"CASTER!"

The mention of his class got the man to stop smiling, instead he seemed to be annoyed now, turning around his annoyance seemed to increase when he saw his 'Master' with her hand next to her face showing off her command seals in all their glory.

"I Ord-"

"I forgot about those"

Before she could even process what happened, Ritsuka felt like she was hit by a truck as she was sent flying into a dumpster with so much force that it bent, the truck in question was the man's forearm, who managed to get close to her before she could even try to order him, and swing his arm at her head.

After sending her flying, he glared at her limp form with mild annoyance, as if contemplating if he should kill her or not, after a while he let out a sigh and looked towards the direction of Olga Marie, who was still shocked about the events that happened.

"You."

Realizing the man's attention was now on her, the white haired women couldn't help but tremble at his gaze.

"Make sure she doesn't die."

It took her a few seconds to process to order, but after a while her terrified expression turned into a frown and she started running towards a knocked out Ritsuka with blood covering the left side of her face.

'Welk that's an annoying fly taken care of, now...'

Turning back, he saw Mash with her shield up glaring at him with a furious expression, just like Olga Marie she was shocked at first at his sudden attack against her Master, but after seeing him almost kill her in an instant..she couldn't help but be mad at him...and herself.

Unsurprisingly the man seemed to be happy about her outrage, one could easily tell from the mocking smile on his face.

"Well then punching bag, my testing session was interrupted by an annouying fly, so let's continue where we left off...Now, come."

TO BE CONTINUED

Author's note:yeah...that toom a while, anyways sorry I had my final exams coming up so I didn't really have time to write this fic, probably my fault for starting it during the end of the school year.

Anyways hope you enjoyed the Chapter and as always I've got some questions for you:

-Do you think Malevolent shrine should be something like a marble phantasm,a Reality Marble(will have to change how it works, or just a complex bounded field.

-Should Malevolent shrine be able to bypass Servant armor?

That's it for now, once again hope you enjoyed the chapter, see you soon(hopefully).
