-Summoning: Shirou Emiya-

He felt himself drifting instead of sitting in the center of the Ginnungagap, something that he strangely wasn't used to. A way to describe it would be...comforting.

But then he heard someone in distress. Someone was in trouble, but their resolve reminded him of someone he used to know. Someone he could never forget.

It was annoying, so he had to go and answer them.

"Hey...for disturbing my sleep, I'm going to kick your ass." His title had changed from "King of Monsters" to "Servant Caster". Wonderful.

The first thing Caster did was pull a sword from his sheath and parry the lance coming for the redhead, his Master's chest. Red eyes connected with the other's, earning a bloodthirsty grin from him.

"A Caster that uses a sword? This is the second Servant that uses a weapon outside of their assigned class." The one who was dubbed Lancer responded, backing away a little before getting back into position.

"Really? Then who was the first one you ran into?"

"An Archer that dual-wielded Falchions and wore red." Apparently this made the blond Caster click his teeth in annoyance before holding his longsword out for a new position much like Lancer.

"Great, he's probably got a hero complex like the last red-wearing dual-wielder I knew." And with that, they dashed forward.

Loud screeching of metal from the two weapons connecting with each other would have made others wince, but seemed to instead excite the two Servants- continuing their flurry dance of blades. Every swipe of a sword and thrust of a lance would be equally parried by the two, only scratches being found on their bodies. Whether it was from the fact that they were Heroic Spirits or the adrenaline, neither of them were tired from the force of fighting. Finally, Lancer jumped back and swung his spear down- going into a different position than before. He could see and feel the Mana swirling around him and backed off a little. If that connected...

"Sorry Caster, but I've got to end it here and now since 'Master' told me to hurry back. It was fun while it lasted though, its a hell of a lot better than running around observing people!" He yelled out as Caster glared at the activated Noble Phantasm, bringing his longsword in front of him instead of the backwards grip like before.

Damn...he could barely feel the Mana flowing from his connection with the red-haired kid.

"Gae..."

"Che, this is going to hurt."

"BOLG!" The bolt of energy from the thrust-forward spear rushed towards Caster as its 'cause and effect' happened, changing from 'the spear pierced the heart' to 'the spear has been thrust, therefore the heart must have been pierced'.

"Guardian!" He yelled out and a shine of a blue aura shield appeared in front of Caster's defensive position, almost being instantly destroyed upon Gae Bolg's connection. Caster grit his teeth, the force trying to push him back and destroy the arte-throwing as much Mana as he could into it before hearing a loud crack from the barrier.

Without thinking, he fell to the side-letting his right arm be pierced by Gae Bolg instead of his heart. It hurt like hell, but at least he was alive...or as alive as a Spirit could be. He was breathing heavily, cringing when he felt the cursed spear's power- not allowing himself the chance to be healed.

"Undodgeable? I want to punch the person who said it was possible. Guess I was lucky today in being a one-handed style swordsman." Caster, letting his currently useless arm dangle while his dominate hand still gripped his longsword (he was surprised that he was even still holding it) and felt the restorative effects of-

Wait, since when did he spawn with Nether Traitor and how had he not noticed in the rush of battle?

"Well, looks like that's my cue. My 'Master' is too much of a coward that he said if my attack fails then to come back." With that, Lancer jumped on the roof of the estate and turned- looking straight at Caster with a bloodthirsty grin on his face.

"Try not to die too early on Caster- I want to fight you again myself." This made the blond Summon Spirit grin viciously, practically matching Ireland's Child of Light's own.

"That goes to you too, Lancer." And with that, the Spear-wielding Heroic Spirit disappeared- taking off once in Astral Form.


Ashi: Hey there! I know its been a while since I've updated anything and most of my uncompleted chapters are in the Drive along with another side story. Basically this is a mini-series of Ratatosk as a Caster class Servant within different scenarios within the Holy Grail Wars, mostly the trilogy and Extra for now. For the next five chapters will lament of his and Shirou's relationship and interactions with other servants. After that will shift to another Master (who you probably already know from reading Caster isn' the best Class) and then to Hakuno.

Whether other TOS characters present will mostly likely be no due to it being Post-Game and over 1000 years passing. However, Tenebrae and Richter will be since they were in the Ginnungagap.
