Fate/Remnant Throne: Shinjuku Shenanigans

Grand Exorcism

Bael seethed at the fact that his failsafe plan, unleash Kali upon Chaldea, was thwarted in such a short amount of time.

Bael: "So it has come to this... Alter, throw everything we have at them. I shall need time to prepare."

Emiya Alter nodded before heading into astral form. Bael then turned back to Shakespeare.

Nearby, the Chaldeans saw hundreds of hornets marching out of the barrel tower. Each of them armed with some kind of submachine gun or rifle.

Y/n remained silent until he spotted Emiya Alter. He then turned to Chaldea's Emiya.

Y/n: "You got a clear line of sight at your alter?"

Emiya: "Crystal."

Y/n: "Alright, let's start the show."

Rin: "Emiya."

Emiya/Shirou: "Yes?"

Rin: "Ugh, Archer."

Shirou: "Sorry."

Emiya: "What is it, Rin?"

Rin: "Don't mess this up."

Emiya smirked before drawing his bow and nocking a certain spiral sword.

Emiya: "... Caladbolg II!!"

The sword was launched and sparked a massive explosion at Emiya Alter's position. In the blink of an eye, the alter servant was right up in their faces and the two counter guardians started fighting.

The others took the opportunity and started taking out the hornets. Both Emiya and Shirou had the same thought in that moment as they fought.

Shirou/Emiya: "I am the bone of my sword..."

Y/n smirked as their reality marble sucked in most of the hornets, leaving a few to get yeeted and deleted by the others as they made their way to barrel tower.

Eventually, they made it to the base of the tower, looking up they saw the ungodly amount of stairs they'd need to climb to even get remotely close to Bael.

Y/n: "Alright. Rin, take the others and clear out the floors between us and the top."

Rin: "What are you gonna do!?"

Y/n: "Go up."

Kali: "I'm going with you."

Mordred: "Same."

Caenis: "I call dibs on the first punch!"

Y/n smirked as they headed outside and began scaling the side of the tower.

Edmond: "Come. Let's clear the lower floors for them."

Rin groaned as the groups made their way up via different methods.

Y/n, Kali, Caenis and Mordred were the first to arrive. The magician and the goddess glared at the demon as he turned to them, still adopting Moriarty's form.

Bael: "I see you made it quicker than expected. Kali, did I not-"

Kali: "Yeah, but here's the thing. I don't take orders from demons. Think on that when you next try and summon one such as I, moorkh."

Kali grinned maliciously as she brandished her sword and flicked it around her wrist thrice.

Y/n then took his chance to be a snarky jackass.

Y/n: "So what was the plan here? Summon a giga-jacked goddess to fight someone who also has deific power and get some form of mutually assured destruction? Great plan in theory... However ya forgot a few things."
