(MC POV)

The final pair was, of course, my two little sisters.

It's kind of weird to see an army of my clones facing an army of mechas that had a head that somewhat resembles my face… I'm not sure if I should really call those the mecha version of me…

"Guess what?! I have a total score of twenty thousand, eight hundred and ninety one kills!" Elaria boasted proudly.

Tsuki scoffed, "Ha! Well guess what? I also have a total of twenty thousand, eight hundred and ninety one kills!"

"You just made that number up!"

"Too bad, I did not~ Those are the legitimate number of my kills! Deal with it!"

"Hmph! Then this fight will determine who's the best imouto for Onii-sama!"

"Bring it!!"

The giant robots started shooting lasers out of their eyes while the clone army charged forward, blocking the laser attacks with their bodies.

Many of the clones fell from the initial barrage but Tsuki was just summoning more of them to replace the ones that were lost.

I don't know how to feel watching a bunch of giant robotic versions of me cutting down clones of me with their laser eyes.

The battle between the two sides looked like it was stuck in a stalemate as no matter how many clones Elaria's mechs destroyed, more of my clones would simply spring up to take their place thanks to Tsuki. But on the other hand, no matter how many clones Tsuki summoned, she could not get closer to Elaria either.

Elaria even made several of her mechs start to launch artillery strikes against Tsuki but she simply made my clones create a shield to defend against said attacks.

I was starting to wonder why Tsuki was simply throwing my clones at the mechs instead of using their abilities when the ground beneath the mechs started to shake and cracks appeared around them.

A second passed before the cracks exploded and my clones burst out from underneath the mechs, attacking them at close range.They then started to fire their own lasers out of their hands, cutting through the mechs like hot knives through butter.

Elaria quickly adapted by having the mechs activate some kind of shield around them, protecting them from the lasers while their hands were replaced with laser blades.

The mech army started to engage the clone army in melee while shoulder mounted gatling guns shot down the other clones that were still rushing towards them from Tsuki's direction.

The previously organised battle line of mechs had now descended into chaos, which I guess was Tsuki's goal from the start.

Despite that, Elaria still managed to have her mechs defend themselves against the onslaught rather effectively.

The mech that she was controlling directly was literally punching my clones away with blinding speed.

"Useless! Useless! Useless! Useless! Useless!!" She shouted in her cockpit, her voice being projected outside by loudspeakers.

I will have to admit though… Seeing a giant mecha version of me doing machine gun punches was actually pretty cool.

Elaria laughed aloud while blasting away a group of clones with a wrist mounted rocket launcher, "Is this the best you can do?! I made my Onii-sama to be the best! Yet your little clones are just inferior imitations of Onii-sama! You still dare to claim you're the better imouto?!"

Tsuki smirked, "Ha! You don't even know that I've been using this time to make the ultimate Aniue! Behold!!!"

The space around Tsuki shimmered before lightning struck down on her, enveloping her in a flash of light before she started to rapidly ascend into the air.

What looked like a giant skeleton appeared behind her before muscles rapidly flowed along the bones which were then covered by a layer of skin.

It wasn't until the flesh reached the skull did I realised Tsuki had created a literal giant version of me, towering over even the mechs that Elaria had created.

In case you were wondering, Tsuki did not transform herself into a giant version of me. I could still see the top half of my little sister stuck in the giant me's chest as though she was growing out of him.

The good thing was that at least he was wearing pants…

"Wahahaha! Behold, my Titan Aniue!! Let's see how your little mechas handle this!!"

The giant me lifted his arm before swinging it down in an arc towards Elaria's mechs, my other little sister making her army fly up into the sky in order to avoid the arm swipe.

Some of them did not make it in time and were swatted away by the giant's arm, most of them breaking apart from the impact alone.

Elaria then had her mechs point their weapons at me and let loose every single piece of firepower they had.

Rockets, bullets and lasers flew towards Tsuki's creation, only to explode against a shield that had materialised into existence around the giant me.

He then raised his arm into the sky before bringing it down, an action that I was very familiar with which prompted me to look up at the sky.

As I had expected, a giant meteor had appeared in the sky and was now descending directly on top of Elaria and her mechs.

She had all her mechas fly towards her where they suddenly started to break apart, only to join back into Elaria's machine to transform it into an even bigger version of myself.

I need to state that there was even some kind of music playing during the transformation sequence too…

Damn… She actually made a megamech version of me…

The mecha me raised both of its arms which transformed itself into giant cannons to point up at the meteor.

A loud boom echoed as the arm cannons were fired, the projectiles flying faster than the speed of sound and exploding against the surface of the rock.

Cracks started to appear on the meteor before the entire thing broke apart into a million pieces, crashing down onto the surface below.

"Wahaha! How was tha--"

Elaria did not get to finish her taunt before Tsuki's giant had rushed towards Elaria while she was distracted and delivered a straight punch at where the cockpit was, blasting it out of the mech's frame.

"Sorry, but that was just a diversion for this~" Tsuki grinned before the giant me opened his palm to shoot a blast of fire at the airborne cockpit, incinerating Elaria who was still inside.

In the next moment, Elaria appeared outside of the World and into my split body's waiting arms, my little sister blinking up at me and still looking quite confused.

"Did I… Lose?" She asked.

I made a face, "Well… Unfortunately you did… But I still thought the giant robot was really cool though."

Her eyes lit up, "Wah!! In that case, could I ask Onii-sama to transform yourself to a giant robot so that I can be inside you? For reference of course!"

…

You know what, that isn't even the weirdest request I've gotten so I guess why not?
