"Leo, what's going on?"
"It's here..."
The monster that ended the previous world, the great doom.
It had arrived.
[Since the mission had been moved forward, the system will now return the power required to defeat the doom.]
As if on cue, my body began freezing, icicles forming around my feet.
"What..? N/N, are you alright?!"
"I'm fine, just.. need some time,"
[Beginning transfer]
Power surged through my veins, I felt a full transformation occurring.
"Ah, it seems she's already started?"
"Who are you? The guards should've-"
"Relax, I'm a friend,"
The cloaked figure approached me, and I recognised the face of the woman I called 'god'.
"It's you..."
I clutched my chest as the power continued to run through my veins.
"Listen now, I can't explain things, we have no time. Instead, I need you to focus on gathering that power,"
She then turns to Elise.
"As for you, I need you to do something,"
"What is it...?"
....
My vision went black all of a sudden, and I felt the time around me freeze.
Batman, Kuro, Shiro... are you there?
I'm here, master. Kuro and Shiro aren't responding though...
What is the situation? Can you see it?
I can't... it seems my consciousness is trapped here with yours.
Damnit...
Batman, can you manifest your physical form?
I'm trying, but it seems your gain in power is also transforming my physical form.. I can't manifest it until your transfer is done.
Understood.
...
"You need to control Y/N. The moment all that power gathers, it might be too much for her current body to handle. Share some of your essence with her,"
"What? My essence?! How can that help..."
"Just do it! Do you want her to live?"
...
She nods.
"Alright, I'll begin the process,"
"As for the rest of you, come out and help hold that thing back, I'll lend you my power,"
As she says this, a pentagon forms below her, glowing brightly. When the light dissipates, what's left is an unfamiliar figure with wings, black and ruffled, wings.
"You...!"
"Hurry up!"
The group head out to the battlefield, witnessing the doom in all its glory.
'God' begins placing her spell on the others, enchanting them with her magic.
With their familiars summoned, and their weapons drawn, they faced the beast who once ended mankind.
...
"N/N, I'm almost done, just hold on,"
Elise stands before an unmoving Y/N, her gaze soft as she recognises the face as the one she fell in love with.
It was one she had seen her whole life, but it didn't feel right.
She just couldn't wrap her finger around it...
Pressing her forehead against the girl, she began the transfer.
In Y/N's consciousness, it's pitch black.
She feels something against her skin, something warm inviting, like the soft rays of sunshine hitting her skin...
So gently.
Batman, I can feel it. It's speeding up.
There seems to be an external source assisting you...
Before long, I had regained my vision.
"Wha...?!"
Opening my eyes, I look at my familiar surroundings, before noticing the shocked Elise having backed away a few steps.
"What's wrong?"
"Your appearance... it's..."
I tilted my head, confused.
I then glanced at the window, and saw my reflection...
My original self.
My hair was a dark black, my pupils the same colour. It was similar to my body back on earth... but a little more... attractive?
This time, I had horns piercing out of my head... wings sprouting from my back, and a tail coming out from behind.
My features looked enhanced, my eyes sharp with a cold gaze.
"What the...?"
[transformation: complete. Welcome, host, to your original body.]
Master, I can manifest my physical form now.
Batman sounds from inside my mind.
I regained my composure and nodded.
As Batman manifested his physical form, I took note that he had become a larger version of his Cerberus form.
If he was a puppy in his first form, in this form, he was now a proper wolf.... Well, with three heads.
"N/N... you have a lot of explaining to do later on... but now, we have to hurry out. They're fighting the beast already,"
I quickly nodded and followed Elise outside, where I saw The others fighting the beast... with not much success.
'God' stood a few feet behind them, using her magic to support and attack... this time, she had a different appearance, more similar to mine, minus the horns and tail.
"Batman, please,"
"Got it...!"
He lunged forward, his eyes shining red as he sank his teeth into the beast.
"Now... perish...!"
He summoned his newfound magic, his form growing larger and more like a Cerberus from the legends.
"Take this opportunity to attack!"
I quickly summoned my magic, not too used to being able to cast spells.
I quickly rushed to the frontlines along with Batman and the other familiars, claws emerging from my skin. With a swift swipe, my claws dig into the skin of the beast, which was impenetrable by ordinary swords.
"N/N, I'm behind you!"
Alisa shouts, casting her protagonist's light magic on the beast.
I quickly dodged to the side, watching as her powerful magic managed to deal more magic after penetrating the beast's outer armour.
"Keep attacking, it'll be fine!"
Prince Leona's gripped his blade, swinging it at the beast with a magic blade-enchanting spell.
B/N was right behind him, providing back up as he used long range attacks instead.
"Move out the way!"
Blair dives in from the sky with her large broadsword, plunging it down onto the beast.
"Batman, use it!"
"Understood. Then, please, lend me your mana!"
As he rushed back to my side, I quickly nodded at him, transferring my mana to him via the familiar pact.
"Aim for the already-damaged areas, and hit as hard as you can. I'll attack with you, so it has no chance to deflect both!"
We attacked simultaneously, not giving the beast a moment to breathe.
Even still, it remained strong.
'God' rushes forward, standing before the beast's outer armour herself.
"Y/N, I hope this ending is enough to satisfy you,"
As she says this, she begins transferring all her magic into a single strike.
"I'll use all that you've given me,"
_____________________________________
How is it? Really unexpected? I'll save you the trouble interpreting if it wasn't very clear... uh, Y/N is a demon... and 'god' was her 'follower' before. (This was hinted from early in the beginning with her familiar being a Cerberus)
She may or may not have been to this world before... :3
