Yashiro POV
All was going according to plan I thought with a smile watching as Taiga passed out from the drugs I planted in her drink.
Now then time to make one last phone call then we can see if you can save everyone William Emiya, I reached down towards Taiga's phone searching for the Emiya house number ah there it is.
The phone vibrated in my palm as I began making the call until someone picked up "hello this is William Emiya speaking how may I help you,"
"Hello William..."
-William POV Switch-
I had just finished washing the dishes with Shirou when the phone started ringing glancing back at Shirou I said, "I've got it you can go take the trash out for me," he nodded "alright then I'll be back soon," he replied hefting the trash bag over his shoulder.
Placing the wet towel down I quickly went over to the phone "hello this is William Emiya speaking how may I help you?" I asked "Hello William...or should I say Taskmaster," came the voice of Yashiro-sensei.
I paused my face slowly shifting into one of panic confusion even how...how did he find out? "confused aren't ya boy," came the voice of Yashiro-sensei slowly I reply with a tone of caution "what do you want Yashiro?"
His voice held a chilling tone "What I want? Well, there are many things I desire William but for now I would appreciate it if you'd come to meet me, I'll provide you with the coordinates if you don't comply consider Fujimura-san's life forfeit," my jaws clench together "really you would kill her? Surely you know what Raiga would do to you?" I questioned as a last-ditch effort to stop him.
"I have got nothing to lose to be honest with you William sure I could be afraid of her father but how can he find a man that's never existed in the first place now I will tell you the location and you will come meet me," Yashiro replies in a nonchalant tone.
With dread mounting I received the coordinates and slammed the phone down at the same time Shirou came back from taking out the trash "I am back William who was on the phone," he asked.
"....Taiga accidentally got too drunk during her date with Yashiro-sensei I got to go pick her up from the hospital," I reply making a bullshit excuse on the spot which thankfully worked "that Fuji-nee I've always told her to lower the amount of alcohol she intakes, but she never listens oh well it's hopeless trying to convince her otherwise alright brother just be sure to stay safe I still have to go finish my homework," Shirou complained before sighing at the thought of homework.
With that Shirou left to his room once he was fully gone, I quickly stepped out towards the shed grabbing the book on the shelf which was actually the lever to the entrance of my real workshop I pulled watching as it slid open.
The front of my workshop contained a bunch of screens along with some notes for the development of some my new experimental time alter spells that I had been working on.
On the left side of the room there were a bunch of racks filled to the brim with rune enhanced arrows 'borrowed' from the school.
To the right there were two display cases one contained my signature black hoodie the other contained an armani suit with a trench coat in the mannequins grip was the Thompsen Contender Kiritsugu gave to me.
Heading over to the case that contained my hoodie I hurriedly placed it on before closing the case and moved over to the case containing the gun and placed it within my hoodie.
With swift precision I released the hidden compartment underneath the case revealing a Calico along with several magazines I loaded one magazine and secured the weapon in my right pocket ready to go.
With that I was all set "I am coming Fuji-nee just hold on," I whispered rushing out of the shed my reinforcement already activated.
The local Fuyuki warehouse was where Yashiro was holding Taiga so that's where I went.
An hour later I finally made it and bursted through the window of the warehouse "Yashiro you bastard where the hell are you!" I shouted.
The sounds of clapping echoed out throughout the warehouse "wonderful performance as to be expected from my top student it's funny really I didn't think anyone could see through my mask yet it's like you always instinctively knew there was something wrong with me but imagine my immense surprise when I finally figured that the Taskmaster was actually you William..." Yashirou said stepping forth from the shadows.
I snarled with anger the Contender now pointed at the mans face "where is she!" I demanded Yashiro smile widens just a bit before pointing at the person tied up person sitting behind him.
The lights turned on revealing the knocked out form of Fuji-nee I get ready to pull the trigger when Yashiro held up a remote "Ah ah I wouldn't do that one click from this button over here and she's dead via celling collapse," he said.
Reluctantly I placed the Contender back inside my hoodie "tch just what exactly do you want from me? Better yet how did you even find out about me?" I pressed wanting to know how he figured out my identity before I took him out.
Yashiro shakes his head with a chuckle "well what can I say it really wasn't that hard to figure out a couple of false kidnappings here and there than boom I was able to calculate the pattern of where the vigilante frequently moved from the academy and your household," he explained.
"But that's not why I've called you here for little hero no I've called you here to make a choice," he continued "choice?" I repeated the man nodded his head "you see in order for a hero to function there must always be someone that he or she has to save....but a hero can't save everybody can they?" Yashiro said moving around the room.
I kept my glare at him wondering where exactly he was going with this "So the choice I give you William is whom will you save your guardian over there or the nearby building of strangers that I've placed bombs in," he revealed at last.
My eyes widen with anger "you sick bastard?!" I shouted as the man pointed at the nearby building with my reinforced eyes, I could see several people tied up with bombs lying beneath them.
Yashiro eyes glisten with amusement "I know I am but what are you?" he replies before laughing "now choose young Emiya who will you save your beloved guardian or a bunch of nobodies," he said pulling out a remote with two different buttons on them.
-Play Time Alter Fate/Zero OST-
"Reinforce legs by eighty percent," I whisper under my breath Yashiro raises a brow "what did you say?" he asked "fuck you that's what!" I replied appearing in front of him and kicked the detonator out of his hand before jabbing my fist right in his stomach causing him to cough up saliva.
I stomped on the detonator destroying it "it's over Yashiro you've lost!" I shouted walking back over to the kneeling man "...is that what you think my student?" he asked before turning around with a knife in his hand it was only thanks to my quick reflexes that I was able to narrowly dodge the blade feeling a brief searing sting as it left a shallow nick on my cheek.
Yashiro spun the knife in his hand before charging at me I met him midway pulling out my own combat knife.
I couldn't keep up with his strikes at first due to his chaotic like style but it became all too easy once I was able to copy his movements anytime, he would strike me at the end I was already there defending.
I blocked one of his strikes and then in a swift yet graceful maneuver I leaped over his head landing a powerful kick to his forehead he stumbled back disoriented and off balance.
"You surprise me WIlliam-" I don't even give the man a chance to speak before pulling out my Calico and started littering bullets all over his body I kept pressing the trigger until I was eventually all out of bullets.
Yashiro's lifeless body slumped to the ground seemingly dead I wasted no time and dashed over to Fuji-nee frantically unwrapping the bindings that held her hostage.
However, the ominous sound of a click reached my ears and I whirled around to find only to see the barely alive Yashiro press...a second detonator I realized with horror "what have you done?!" I shout.
The man giggles blood leaking down his mouth "hehehe scorched earth," he said and then boom the building that held the other hostages exploded making me scream with anguish "NOOOO!"
"I am...going to kill you!" I raged grabbing the still laughing man by his collar "hahahaha so tell me hero how did it feel knowing that you couldn't save them? How does it feel being broken by me hehehehehehe arugh-" I cut him off my hand rotated snapping his neck.
There's still time to find survivors I just need to hurry and drop Fuji-nee somewhere off safe yeah that nearby roof top will do "reinforcement ninety percent," I chanted before leaping up on top of the roof quickly I placed her down against the wall and then went back down to the collapsed burning building.
I searched through every piece of rubble hoping to find someone only to find nothing but dead corpses I cried and screamed collapsing on the ground.
I thought I was a hero so why...why couldn't I have saved them "a hero can't save everybody," the words echoed through my head.
He was right that fucking bastard was right! I screamed in my head punching the ground repeatedly.
-the next day Taiga had her memory manipulated by William before she woke up so she thought she had a normal date until she got drunk, and the body of Yashiro was never found because he destroyed the body with fire-
"I can't believe I screwed the date up damn stupid alcohol," Fuju-nee cursed banging her head on the table while both Sakura and Shirou patted her shoulder trying to comfort her "there there Fujimura-sensei I am sure there's always next time after all there's plenty of people out there Yashiro-sensei probably just wasn't the one," Sakura said in a soft tone.
That only just made Fuji-nee cry harder but my attention wasn't focused on the conversation rather on the tv where the news station was covering the explosion.
The grip of my hands tightened as the memories of that night replayed themselves through my head Yashiro might have been right...but even so though I had still managed to save Fuji-nee and at the end of the day she was more important to me compared to the mass of nobodies.
"Hey Fuji-nee stop crying now and let's go to Raiga-jisans I need to ask him something," I shouted which made her cry even more because I was being mean to her.
-end of the prequel-
I am not even going to ask about what you guys thought of the prequel because I know no one even cares about it and I will admit that this was rushed because I was just reminded earlier that I should've added more depth to the character before heading into the main story.
Well, any way with this out of the way we can finally get back into the main plot so celebration!
