One year after the conclusion of the Holy Grail War known as Heaven's Game and its sister game of the same name, a new grail war has begun less than a year later.
"EVERYONE GANG UP ON KIARA!" I shouted as Archer, Rin, and Caster prepared to fight, Neo sprinted into battle slashing at Kiara's vital points and her joints forcing her to go on the defensive, "YOU! OVER HERE NOW!" I snapped at Ingel who crawled over to me, "Sit there, shut up, and I swear to the gods if you die I'll resurrect you so I can kill you myself!" I snapped, "Yes Ma'am!" Ingel said, "Good boy. Now." I said as my family crest appeared on my back, "it's time for Mommy to get to work." I said calmly as my cloak appeared on my shoulders, "What are you?!" Ingel said, "A damn good mother." I said as I opened fire on Kiara with Rin and Archer, suddenly our attacks hit some sort of wall, "Oh did I forget to mention that I can control (y/n)'s reality marble? Cause I can." Kiara said, "Any advantage you gain I can just say no and take it away. This reality marble was your only saving grace!" she laughed, "I am, the bone of my sword!" Archer said, "ARCHER DON'T!" I yelled, "Steel is my body and fire is my blood I have created over a thousand blades. Unknown to Death, nor known to Life. Have withstood pain to create many weapons yet, those hands will never hold anything So as I pray, Unlimited Blade Works!" Archer shouted dragging us into his reality marble, "There now she can't control our surroundings." he said as he sprinted into battle with Neo, 'But now (y/n) can't mount a counterattack.' I thought, suddenly (y/n) grabbed a short sword and stabbed Kiara in the back, "I'm kinda proud of him." I said in shock, "KILL HER!" (y/n) yelled as we all attacked at once.
The reality marbles shattered leaving us all exhausted, "We did it, we killed Kiara!" I laughed happily. Suddenly we were pulled into a reality marble that resembled an infinite library. "E is for extinction, of all your puny races. R for revolution which will be televised. F is for how fucked you are, now allow me to reprise. T is for terror upon you I'll bestow." a woman sang drawing our attention and instilling terror into our hearts.

My name is Kiara Sessyoin, and I'd like to say, hello." she said, "OH! I have chills! I feel like I should blast one of you to death, but I won't that'll make my later plans more difficult later on." She said, "DIE!" (y/n) yelled as he created a sword and attempted to stab Kiara, "Now sweetie did you think it'd be that easy? I'm nothing like the me you killed with the grail or just now in your head." she said, "Also don't you all go thinking that I'm not impressed with you. Cause I am, you did more with less than I ever expected, not that amounted to anything. Although it did make retrieving that portion of my consciousness, that I placed in him before I died, a bit easier." she said, "How the hell are you alive?!" I snapped, "You wanna tell them what you did or should I?" she said as she looked down at (y/n), "Fine. So who knows how the last Heaven's Game ended?" she asked, "No one? Fine, party poopers. There was no winner. For the first time in history, there was no winner and the grail wasn't destroyed resulting in there being no winner!" she laughed, "How is that possible?" Archer asked, "A very good question! And I'll answer in kind, a show of hands who knows how (y/n)'s powers work?" Kiara said as she raised her hand, "No one? Just me then? Fine, I'll explain, and it figures no one would pay attention to the most powerful fighter among them. Imagination's End is (y/n)'s reality marble, and damn you that name is so dumb yet so fitting, and the more I think about it the more I like it! Anyway, the only limitations his reality marble has are his mana and his imagination...and any arbitrary limitations he makes." she said, "My son is that powerful? So how did he cause the war to have no winner?" I asked, "He watched Naruto." she said, "What?" we all said, suddenly (y/n) appeared next to me and the one who tried to kill Kiara faded into oblivion, "A simulacrum?!" Caster said, "Ding ding! Give her a cookie." Kiara said, "He can recreate abilities perfectly inside his mind's eye, but outside his reality marble, he needs to apply the concepts and figure out how to make them work." she said, "A simulacrum is as close to a clone that you can get, but he's altered memory. Tell Caster when did you get the idea to create simulacrums?" she said, "I've always...no...but when did you?!" Caster said, "When we met." (y/n) said, "WHY?!" Caster asked, "Don know." he said, "You know I should be mad, but I'm not, I'm just impressed." she said. "As fun as this was, (y/n), I'll give you one free shot to kill me once and for all with your doomsday plan. Go on, summon Kiritsugu." Kiara said, suddenly a man appeared and shot at her while running toward her, but in an instant, he was cut to shreds while he appeared behind her, "Wasn't that a waste of time? Oh by the way I can use all (y/n) abilities." she said, "Now before I go I'll tell you how this war will end." she said, "You're gonna die." she said as she pointed at Archer, "You're gonna be extra dead." she said as she pointed at Caster, "You're gonna die slowly and at the hands of Archer and Caster." she said as she pointed at Neo, "You're gonna join the grail I escaped from to make it even more powerful." she said as she pointed at Ingel, "You're gonna live heartbroken and in too much pain to kill me." she said as she pointed at me, "You're gonna be filicided." she said as she pointed at (y/n), "And as for you...moon." she said as she looked at Rin, "You have three days before the slaughter begins. So strategize, screw, take up knitting, or pray to your heart's content, but just know, I won't be listening." she said before she vanished and we were left alone outside her reality marble, "We're fucked!" (y/n) said, "I know you're right, but you're getting soap in your mouth later." I said in shock, "WHAT DID SHE MEAN BY MOON?!" I WANT ANSWERS DAMN IT!" Rin yelled.
"Medea." Archer said, "Shirou, I'm scared. Kiara is more than powerful enough to do everything she said." I said as I clung to him, "Medea, I swear to you, I will protect our son." he said as he kissed me, "I know you will. And if Kiara should take over my mind, I want you to kill me. Don't hesitate." I said, "And I want you to do the same to me regardless of if I try to kill (y/n). When we kill Kiara I want you to kill me." he said, "I already was going to. You think I'd let anyone else kill you, my sweet boy." I said as I kissed him. "You get back in that bathroom young man and you better put the soap back in your mouth or I'll get the belt." I said as I sat with Archer and cuddled with him. "So are we..." Archer asked, "Oh you're not getting any sleep tonight." I said.
