I ain't your Servant! 4 - or 'When the Master of Chaldea simps for Fanfiction a bit too much' (FGO, AverageGuySI!Servant)

Melusine charged at the castle with the right kind of ferocity.

At the same time, she was moderating her flames and her ruthless attitude as she had several 'troops' to rely upon as the defenses in the Castle were indeed proving to be a lot- enough to warrant further assistance compared to her lonesome self. So, she was having a blast tearing apart defenses, enemies and drawing all sorts of attention to her.

What about... me?

Well, that's simple, I was sneaking into the the castle and I was glad I found a vent to avoid detection. Since most of the guards were outdoors to face the huge distraction I had Melusine run through the gates and all around, I was hiding away mostly from the tentacle monsters that were sprawling around the halls.

Not truly a smart replacement, but gifted with enough awareness of their surroundings to be able to hear and, to some extent, also see. Both senses were limited due to their odd bodies, granting me the opportunity to pursue my main target without causing a ruckus.

Eventually, however, I had to slither out of the vents and make the last lap to the throne room on my own. Everything was settling in the right place. Even the 'greetings' I got as I kicked the throne room's door open was just as I had expected.

After all, I was suddenly swarmed by tendrils that suddenly pulled me fast into the throne itself.

An empty throne at that as my target would never take the place meant for the one in his heart. The one and only Dragon Witch, who was currently fighting against Guda and co., would not see of the demise of her 'friend' and true creator: Gilles de Rais, the Demon Marshal.

"I... I am surprised. I really am," The man muttered, awed and yet annoyed, his eyes inhumanly wide open as he regarded me. "Your plan... what is it? What manner of rationality drove you, a feeble man, to try and face of a challenge above your standing."

I blinked, looking up to Gilles and... giving him a smile.

"Do you remember... the coronation of King Charles?"

The Caster frowned, tilting his head to the side and strolling away as he mused over my words.

"The coronation? Why yes, the fool that took the crown, he told us we were allies. He betrayed Jeanne-"

"What about Jeanne, Gilles?" I pressed, giving him a dry look. "What Jeanne? The young maiden or the spirit? The one that paid the ultimate demise or the one whose legacy lives on forever in the soul of the French People."

"I-It's not the same!"

"You're right. That's why the Grail didn't let you bring her back to life," I continued and nodded, my words actually doing their job and freezing the fellow Caster in his steps.

"How- How do you- YOUUUUUUUUUUUUU!" He growled angrily, almost frothing from his mouth at the sheer rage consuming him for a moment. "The Grail- it refused to give her back. Why did it refuse?! WHYWHYWHYWHYWHY!?"

"Because the Jeanne you remember nowadays is not the one you knew once. It's not just Jeanne. You idolize her, but you once knew her. The one that wasn't just the heroine of France, but a young woman with her own flaws- each of which made her perfect to your gaze."

"N-Noooo! She was not- she would never be imperfect."

"She was not. At least, not in your gaze and mind. You just forgot with all that fog you took over, all that rage that made you unwilling to accept the truth. There are two Jeanne, one who died because war is ugly and one that still keeps that untouched aspect of the true Gilles protected even now."

He hesitated, his palms twitching and his scowl worsening in a rabid expression. It was my opportunity to act as he was distracted, and I did so. Closing my eyes, I remembered what my 'Fellow Italian' back in Chaldea told me I had to say and do to muster my last Noble Phantasm.

"Activation Noble Phantasm: Fictional Reinforcement."

Surprise flashed on Gilles' eyes, but he stared in shock as my body was wrapped in a red light. Tendrils from the side of the walls rushed towards me, planning to skewer me up. Yet...

"O-Oh?" Gilles hummed in surprise as he saw a long object now in my palms rushing in a precise swing, easily cutting the tendrils and freeing me before I could get impaled by the approaching tentacles.

I landed on the ground, the dust giving me some cover while I smiled at the successful application of my ultimate Noble Phantasm. Fictional Reinforcement was my 'best tool' when it comes to many things. It allowed me to temporarily use the powers of characters I wrote that could become Heroic Spirits within the criteria of the Grail.

It was a risky move since it relied on the notion of me thinking of the right Servant, being in the 'right spot' and... Well, me knowing if I could win the battle within the time limit it had. I couldn't spam it, not when once the use was over, I would be unconscious for a few hours.

I tried it once with Da Vinci's assistance, and she confirmed that the weakness was tied to the 'abnormal prana input' going into my body and overloading it once the NP was deactivated. So, I had to move fast against Gilles, but I was glad that my choice was the one I had planned for and... the one that was best for this sort of situations.

"Y-You... Why do you- why do you shine like her!?" Gilles snarled. "Jeeeeaaaannnnneeee! HOW?! HOW IS THIS POSSIBLE?!"

"Because," I hummed, standing up and dusting my new uniform's jacket and pants. "The spirit of a nation, for a Heroic Spirit such as my current Reinforcement and Jeanne D'arc, is quite the same. We embody our respective countries' pure and untouched dignity and might," I paused, shifting the staff holding the proud British flag that 'I' remember holding during that grand Operation over Belgium. Back in the Great War, in the Trenches, with all people serving the British Empire. "My Noble Phantasm grants me this chance. Rejoice, Gilles de Rais, for I will show you that no matter how many years go by with the passing of national heroes, their souls burn strong within the identity of our fellow citizens."

I took some steps forward, then smiled. "Call me Oswald Mosley, General, Viscount and, without a doubt, the one that understands Jeanne the most since I know how it feels."

The last claim had him raging as numerous tendrils soared to intercept me as I ran towards him, yet my flag savagely cut down the hurdles, destroyed the enemy, wrecked the opposition and then, as I got within range... I used my second weapon.

Swift bullets soared around the tendrils, the mystified version of the alternative first SMG known as Rapid Gun was uncompromising as it shredded the walls of purple tentacular flesh between me and Gilles, while also shredding the arm holding the Prelati book.

Gilles didn't get much of a chance to speak, merely turning to see me rush at him, the flag already swinging and... off with his head. His body fell, dark mist forming from its collapsed self as his life was ended. But, from within the shroud of darkness, a small red chest with golden details appeared before me.

It shook a bit mid-air and then... it opened. The Holy Grail was indeed there and-

"...I expected something more about the Grail," I mumbled, but I didn't pause as I reached for the golden cup. "Romani, I got the Grail."

"The Singularity is indeed collapsing. Order is being restored so... you will all be shifted back to Chaldea."

I nodded, staring at the Grail for a moment. It felt so odd that such a little thing, that was used by Chaldea to produce 'Palingenesis' for Servants to boost their Level Cap was actually able to produce massive scenarios. It was a bit unbelievable, but I didn't think too much over it as my body was suddenly wrapped in a familiar light and... we were back 'home'.

"SENSEI!" Gudako was there. Fuck.

Before I could say or do something, she just bolted after me and then jumped me. I caught her in a bridal carry and she giggled.

"Oh! That's Oswald Mosley right? From 'Quite the Age of Plenty', right? Did I get it right?"

Goddammit, I thought the Gacha-addicted Gudako was bad, this one is actually worse!

Luckily for me, a certain lovable Eggplant was there to help me peel her off of me. And I realized that Jeanne and other Servants had carried over to Chaldea. I guess that cuts down the issues of Gacha to some extent but... Jeanne was giving me a rather curious look. And I realized that it was due to my NP still being active.

Well, I had to deactivate it and, giving a dry look at Gudako as she still questioned me about what else I could do with my Fictional Representation, I decided it was time to let things be taken over by a reliable individual as I prepared to fall unconscious.

"Melusine," I hummed, glancing at the short Servant. "You have permission to carry me to your room for cuddle-sleeping, but I require you to not let any sexual molestation happen to my body while I am unconscious."

Considering how much fun today was and how tired she looked, the Lancer appeared delighted by the concept of some 'deserved' cuddling.

"Understood, Mast-er!"

Right as she was answering, the NP went out and I instantly lost consciousness. The next moment I was awake was in a bed with Melusine snoring against my chest. Both of us were still dressed comfortably and nothing scandalous was going on.

I would then be told that Gudako had 'waged war for the cuddles' right'. Melusine had, reasonably so, defended 'my honor and my purity' from the orangette.

Ah yes, my little Fairy Lancelot couldn't get any more loyal (and cute)..
