You can't run. You can't dodge. You can't even speak; the son of Zeus has already reached you and is delivering the first and final deathblow to end you. Strength, agility, endurance, intelligence, cunning; none of it matters, you simply can't match the raw might of Hercules. Or was it Herakles? Fuck it, it doesn't matter; you're dead anyways.
The blow comes...
...And on it's own, by sheer instinct and skill, you sword arm moves. You're blown away; the force from the attack like a typhoon, managing to land and anchor yourself several dozen feet away from the mad demigod. You...you can barely comprehend it; you're alive. But, but how-
Greatest Swordsman in the World. Holy shit; that....that was pure skill at work, bestowed by your Noble Phantasm and usual boasting and bluffing. You are weaker than him. You are slower than him. You sure as hell can't tank a blow as well as he can. But with this...with this you were more skilled than him, and that made a difference.
To block that blow would've been suicide, and dodging was impossible. Like a rock against a hammer, you would be crushed to dust; no amount of skill would allow you to block or dodge that kind of strike.
So, you didn't. Instead of being the rock against the hammer, you were the leaf against the wind; you went with the blow. With perfect skill that transcended comprehension, you used the force of the attack to fling yourself away from him. It was something beyond even those who have dedicated their lives to the blade; a single centimeter off, and you would've died.
But you didn't. You were alive; and you can keep this up. Again Berserker comes at you and swings, and again you go with the tide. But this time the enraged giant knew what you did, and quickly followed up with another blow. So again you go with the force of that blow.
And again. And again. Over and over this repeats; for the mortals watching the spectacle, they saw Herakles swinging his blade rapidly, yet not a single blow landed. The bard was flying all around him, each blow from his foe serving only to further keep him in motion; away from death. All the while, you were planing on how to escape.
You couldn't land a blow on him; to do that would leave you too open to an attack, and that would kill you. You also couldn't escape, because you needed the force of Berserker's blows to keep you from being hit; the second you weren't being struck was the moment you died. However, you had a plan.
You know that you can overpower a spell to perform far beyond it's normal capabilities, it's a skill some wizards know. However, you yourself have never done it in your lifetime. It was something you never bothered trying nor had the prowess to accomplish.
But you weren't exactly human now, weren't you? Look at the priest, how easily you changed his worldview with simple words and minimal effort; you had transcended beyond human limits. So, it was worth a shot, right?
You quickly set up a Darkness spell and a Giltterdust spell; and try to dump as much power as you can into both, consequences be damned. The moment Berserker swung for his second strike, you let loose the combined spells. You hope to God this works...
The spell... explodes, for lack of a better term; in a mix of pitch black darkness and glitter, like a inverted ray of divine light. It hits Berserker right in the face and he starts to clutch at his eyes, stopping the swing of his stone blade. Finally, an opening to escape. You cast Obscuring Mist several times, enchant you eyes you can see through invisibility, and find where Shirou is.
You find him; he's right where he was before this whole mess started, thank God.You cast several Grease spells on Herk before teleporting over to the boy. He jumps back in shock, but before he can say anything you grab him and teleport right back to where you were summoned.
In a flash, the both of you crash into the floor of the shed; apparently being scared out of your wits can affect this sorta thing, who knew? Groaning, you get up, and notice a gem of some sort. You pocket the thing for later; Shriou doesn't seem the type for jewelry and it could be something belonging to another Master.
Shirou also gets up and asks, "Are...are you alright, Tandem?"
Do you look alright?! Well, you can't exactly blame the kid, he looks as shocked and scared out of his wits as you are; "Yeah...yeah I'm fine, I've been through worse. Still, looks like we just found the most dangerous motherfucker on our asses, eh kid?"
You hear him scoff, "Heh; yeah, that's going to be near-impossible to handle. Seriously though; you had sex with Athena?"
"Oh come on! She came onto me! It's not my fault, and I already got my ass beat by Zeus and thrown off of Olympus; not to mention losing my status as a Demigod."
"Riiiiiiight; of course she did," wow, kid didn't seem like the snarky type; wonder what brought this on, "Anyways, it's late and I doubt we can get much else done. I'm going to sleep and we can discuss what to do from here tomorrow, agreed?"
"Kid, you just took the words right outta my mouth; I'll keep watch for anything suspicious, in case someone gets any bright ideas. Perk of being a Spirit-thing, no need for sleep. Get some rest, we'll know what to do in the morning."
Shirou thanks you, and decides to finally get some goddamn sleep after the hell he's been through. Since you don't need sleep; you decide to patrol the house and keep watch. Thankfully, it looks like nothing else exciting or of note was going to happen; as morning finally comes and your partner begins to wake up.
Now then, what's the game plan?
[X] What will you discuss with Shriou?
Yes, you do bring out the snark within Shirou; why do you ask?
