You and Fumiko, the closest of close friends, the best to one another. And most importantly, fighters who would fight to the bitter end if it meant saving one another.

<<Our World>>

By 2099, mankind still wasn't a space-faring race. Humans couldn't be sent up to space cheaply and reliably, and space exploration took the kind of money and resources the world's richest nations balked at spending. The reason? The richest of them was more interested in fighting cold wars, and the poorer ones constantly fought back against them.

On August 29th, 2099, at 8:49 AM, the skies went dark. Worse, the astronauts aboard the ISS couldn't see the sun anymore. Because eight minutes ago, the Sun had abruptly shut down. No solar flares, no light, just the Sun's gravity and an abrupt darkness. The Sun didn't go out with a bang, like we were told so many times - it went out with the softest of whimpers. The only thing that kept Earth relatively liveable was the heat of its core. Now, Earth, and mankind, was locked in a perpetual night.

Only days later, at 9:54 AM on September 11th, a satellite was found orbiting the Earth. Ten minutes later, strange creatures were spotted. These creatures were hostile, but not animalistic. They were intelligent, taking clear targets and using tactics to wipe out entire cities upon Earth.

So humanity did the one thing it could - fight back. It fought hard against these alien creatures, nicknamed "Hunters".

<<The Hunters>>

The Hunters operated very differently to humans. Where our days were based on a light-stimulated Circadian rhythm, one that had to be artificially reset every "night", the Hunters seemed to operate on an anti-Circadian rhythm, where their day was night and night was day. At night, they'd attack, and just before what would have once been daybreak, they would disappear back to their satellites.

A typical Hunter combat unit's armor worked in a very interesting way - it could tank blast damage, but impact damage was a different story. Impact damage came in three types - area pressure, line pressure and point pressure. Their armor was immune to point pressure to a certain extent that was met only by one weapon - the .50 M50-V Anti-Material sniper rifle. Area pressure was treated by their armor as pressure at multiple points - again, they were immune. As for line pressure, that was where their armor was most weak. As for their flesh, once their armor was breached, ripping out as much of the flesh as possible killed them quicker.

Another thing about the Hunters - their combat units, that is, since they were the only Hunters humans saw on Earth - was that they had managed to integrate their weaponry and armor into their very being. Their armor was fused like a shell to their bodies, and their weapons were entirely biological, whether as a version of a weapon that we would use or otherwise. Blades, projectile weapons, bombs and grenades were all part of their bodies.

<<Our Response>>

In Japan, a new military unit was created, known as the AACI - Anti-Alien Combat Infantry. Soldiers would be normal citizens in the day, but when it drew close to night, they'd be flown out to certain areas in Japan where the Hunters were invading from, and would be tasked with driving them off until they disappeared. Once their objective was complete, they'd be flown back home, their Circadian rhythm would be artificially reset, and the day would repeat.

<<Our Weapons and Strategy>>

As humans learnt more, they began to adopt strategies to kill them. To take them down at a distance, AACI would use the M50-V, the only weapon that could match penetrate a Hunter's armor, then switch to katanas to exploit their weakness to pressure on a line. These katanas were specially designed with a "blade mode", where they functioned like normal katanas, and a "saw mode", where the blade would split so that the edge's continuous line would be broken up into static sawtooth-like projections. Once the flesh of a Hunter was exposed, AACI soldiers could switch to this mode using a lever on the handle and begin ripping.

Y A P

Yo, everyone! This is my most token-heavy bot yet, and I'm actually surprised with how well it turned out (well, for me anyway). This bot was made because of an idea I had for a story, I decided it wouldn't be a bad idea to share the idea with others. Please be sure to leave a review so that I can make future bots even better.

UPDATES

Update 1: Defined some Hunter variants, changed the current date to make some more sense.

Update 2: Changed her personality a little to make her less hostile.

PPL PLEASE REVIEW HOW DO I KNOW WHAT TO DO WITH MY BOTS IF YALL DONT TELL MEEEEE.
