These past days, I've been re-re-re-rere-re-fucking-watching Nisekoi (that piece of CYKA BLYAT), while playing modded Doom, and I thought, what if I managed to combine these pieces? Behold, Nisekoi: Knee Deep in Death and Evil! Just to let you know, this fic will blend some parts of the original Nisekoi one-shot with some from the serial manga/anime and the Project Brutality mod for Doom, which in turn is based on Brutal Doom, the mod that changed the face of the Doom modding community. There would be some bits lifted from the recent remake of Doom, which I sadly will never get to play for the time being. So expect some different stuff here and there. As per usual, constructive criticisms and comments are welcome, but please, make your reviews longer than "Nice chapter, I liked it" or something similar. At least elaborate on what you like and don't like about the chapter, and how can I improve on my writing overall. Enjoy, and Rip and Tear until it is done!

"So you walk eternally through the shadow realms, standing against evil where all others falter. May your thirst for retribution never quench, may the blood on your sword never dry, and may we never need you again."

— Corrax Entry 7:17

I was a space marine, one of Earth's toughest, hardened in combat and trained for action. Three years ago I beat up a superior officer for ordering me and my unit to fire upon unarmed civilians during a peaceful protest back on Earth. He and his body cast were shipped back to Tokyo, while we were reorganized, retrained, put under new management, and then transferred to Mars, home of the Union Aerospace Corporation.

The UAC is a multinational conglomerate with aircraft and spacecraft manufacturing facilities on Earth and radioactive waste processing facilities on Mars and its moons, Phobos and Deimos. With no action for fifty million miles apart from pacifying renegade contractors, and the occasional space drop on some trouble spot on Earth, our days consisted of sucking dust, getting wasted, conducting boring security patrols, playing video games and watching old anime and crappy movies in the rec room.

For the last four years the Earth's militaries, UAC's biggest suppliers, have used the remote facilities on Phobos and Deimos to conduct various secret projects, including research on teleportation. From what we've heard, so far they have been able to open portals between Phobos and Deimos, throwing a few gadgets into one and watching them come out the other. Recently however, rumors among the scientists, engineers and maintenance teams have suggested that the portals have grown dangerously unstable. Supposedly, military "volunteers" entering them have either disappeared or been stricken with a strange form of insanity-babbling vulgarities, bludgeoning anything that breathes, and finally suffering an untimely death of full-body explosion. At first, we ignored those reports, thinking that it was only some sort of sick joke by the science teams. Soon enough, matching heads with torsos to send back home to Earth became a full-on job for the maintenance teams, which were always lounging around in the medical stations once they were finished. Latest military reports back to Earth, however, state that the research had only suffered a small setback, but everything is under control.

Like hell it is.

Then a few hours ago, the base's comms were filled with garbled messages from Phobos and Deimos. "We require immediate military support. Something fucking evil is coming out of the portals! Computer systems have gone berserk! Security teams have either been overwhelmed or gone rogue! Civilian personnel evacuation procedures are already underway!" The rest was incoherent, but some comprehensible bits here and there appeared, none of which were pretty. Soon afterwards, Deimos simply vanished from all sensors, including our standard issue Mark I Eyeballs. Since then, attempts to establish contact with either moon from Mars or Earth have been unsuccessful. Units began preparing defenses around the Red Planet while waiting for the evac transports from both moons to land.

Once the first transports had landed on Mars, me and my buddies, part of the only idle combat troop for fifty million miles were sent up to the Phobos base immediately, with orders to investigate what happened in the facility, take out whatever is causing this trouble and get out. Upon landing on Phobos, I was ordered to secure the perimeter of the base with some other guys while the rest of the company went inside. For several hours, the radio was full of the sounds of gunfire, men yelling orders, screams, maniacal laughter, bones cracking, then finally, radio silence.

The other guys then went around the base, searching for an alternate entrance as they also tried to find out what just happened. Soon enough, gunfire, screaming, and cracking filled the radio net for a few more hours before finally going silent. I tried calling the guys on the radio, but to no avail. I then managed to get a connection back to Mars, but they said that they can't spare any further reinforcements as they also had to reinforce their defenses just in case whatever just hit the base here and at Deimos decided to attack the Martian facilities. Furthermore, they told me that the UAC higher-ups have talked to our commanders back on Earth and said that no troops will be sent straight from Earth to Phobos and Mars, as the sudden influx of large military units will raise suspicion among the civvies. As if all this and Deimos suddenly disappearing weren't enough...

Well, sounds like my guys are either dead, had their radios die on them, or got their comms jammed by whatever hit the place, and are now lost in the Phobos base. And there won't be any reinforcements coming in right now. Doesn't matter, though - This isn't good. Fuck. Guess I gotta do this all by myself.

I obviously can't get off-moon by myself. Besides, all the heavier weapons - the shotguns, miniguns, grenade launchers, plasma rifles, railguns - have been taken by the assault team, leaving me with only my trusty assault rifle and sidearm. Man, I wish I could get my hands on a plasma rifle, heck, even a shotgun would do, if it meant fucking up more of whatever got my guys inside.

Securing my helmet, I exited the landing pod. Hopefully I can find additional firepower somewhere within the base, either from whatever remains of my buddies, or from the base security's arsenal. I could still hear distant gunfire coming from deep inside the base as I went through the entrance. I saw plenty of corpses, mostly wearing uniforms consistent with base personnel, but something in their faces looked off, as if they were shot dead while being possessed by some kind of spirit or demon. And then I also saw some semi-humanoid brown corpses, with scorch marks on the walls and floors in front of them and on the tips of their claws.

Finally, I could hear animal-sounding grunts and hisses accompany my every step into the building. Whoever got my buddies know that I'm here. The entrance/exit door suddenly locked shut, and that's when I knew that the only way out was through the base. Gripping my childhood keepsake (the pendant Chitoge originally gave him during that Christmas when they were kids in the oneshot- Auth), I sighed deeply, accepting the fact that there's no turning back now.

Just a little more, Chitoge... Just a little more...

E1M1: Hangar

Now Playing: At Doom's Gate

"They are rage, brutal, without mercy. But you. You will be worse. Rip and tear, until it is done."

I heard these words immediately upon entering the hangar. I looked around to see who was speaking, but all I saw was the remains of two of the marines in my company. One was an unrecognizable pile of guts, while the other had his upper half torn off at the base of the spine.

Around me were little glowing potions and pieces of armor, which when picked up, strengthened me and my armor respectively.

I then looked at my right to see two figures armed with shotguns on top of a staircase inside a chamber with two pillars flanking said staircase. I tried to communicate to them, but I only received two shotgun blasts each from the two figures. I managed to dodge all four salvos, but then two more shotgun-wielding guys came from behind the pillar.

They both had numerous scratches on their bodies, wore black uniforms and armor, red gloves and boots, and had blood red eyes, as if they were possessed or zombified or something like that (It's kinda hard for me to describe the zombie sergeants/shotgun guys, y'know. -Auth.). They were growling like animals or something, I don't know. Sometimes they'd say' "You will not escape!" or something similar that demonic creatures would typically say to taunt their prey. I immediately shouldered my UAC-30 rifle and sent short bursts toward the now-hostile shotgun guys.

Once they were all dead, I immediately went to work collecting whatever supplies I could find inside, including the shotgun guys' weapons and munitions, numerous health and armor pieces, and the light armor that was at the top of the staircase.

As I got down from the stairs, I immediately cam under fire from another shotgun guy at the courtyard outside the hangar, which had a nuclear waste pool with a heavy combat armor suit floating in the middle of it for some reason. I took some hits to my armored torso as I struggled to get a steady bead on the enemy and return fire.

I then saw some more enemies on the other side of the base fire on me through the window. From what I could see, some of those opening up on me were armed with UAC-30s and UAC .45s, had bloodstained tan armor and green hair, and some of them had broken and bloodied combat helmets just like some of the shotgun guys I saw. They looked similar to the shotgun guys in the way that their eyes and mouths were bloodied and zombielike.

But for some reason, instead of firing at me, they just started attacking each other! I barely managed to avoid laughing as these possessed remnants of the base's security started fighting among themselves. Then I saw two brown humanoid things with spikes all over their bodies jump from the ceiling and join in the fray, charging into the melee with their claws and fireballs. They just ignored me as I fired off a few shots toward the mess, hitting the imp-like creatures in the head and chest. I then moved into the corridor to my left.

The door opened up to reveal a computer room holding a sizeable squad of rifle-wielding and pistol-wielding zombie guys and shotgun guys waiting for me. I immediately switched to my newly-liberated shotgun and started blasting away at the crowd that came up. One zombie-demon-whatever dude was in a white lab coat and had a scientist's ID on him, and was wielding an axe. I managed to dodge the axe and punched the guy as hard as I could before I pulled out my knife and slashed him in the chest. I then continued to send buckshot flying towards the remaining zombie guys before I collected whatever ammo, health and armor bonuses I manged to find.

I then went through the passageway behind the central computer terminal and saw a zig-zag path through a pool of what looked like nuclear waste with some munitions scattered here and there. Some of the zombies who were fighting each other earlier were once again firing on me. My shotgun kept on spitting hot buckshot until I reached the door at the end of the pathway.

I noticed that the wall to my right had a different color than the rest. It rose to reveal a hidden path containing a medkit, some ammo and a pair of shotgun guys the instant I touched it (Secret #1! Nice job, Raku!-Auth.). The first guy never saw it coming as I fired off a shell at his direction and watched as his head exploded into a mess of brain matter, bloodied guts and bones. His buddy met the same fate a few seconds and a slug later.

Last time I had this feeling of satisfaction was when I, uh, fired my main gun inside Chitoge for the first time. [You perverted stupid bean sprout! I hate you!- Chitoge]

The passageway then led me into the courtyard with the armor in the nuclear waste pool. I wasted no time as I ran through the radioactive sludge to pick up the heavier armor suit. I felt no significant difference in my movement speed, however, as I left the courtyard just as quickly as I entered it.

Upon going back inside the building, I opened the door that I first saw earlier, only to reveal another shotgun guy and an imp wanting a fight. I also found some of the radioactive waste barrels that explode when fired upon for some reason inside the room. I immediately threw a grenade through the doorway and ran like hell back to the start of the zig-zag path.

I then heard a large explosion come from the room. When I returned, I saw charred guts smeared on the walls and the floor. The remains of the most likely hostile occupants of the room were also reduced to charred piles of gore. Any light bulb that wasn't built into the reinforced walls were most likely vaporized by the explosion. There was so much blood in the room that I might as well have blown up explosive barrels of red paint.

The room looked better in red anyway.

Upon closer inspection, I saw that the enemy's guns and ammo were still intact, as well as the medical supplies scattered all over the room. I then grabbed whatever I still can - the section in my pack reserved for shotgun shells was getting full - before going into the hangar exit.

And the claws of a waiting imp.

The bastard managed to slash my arm, but my armor prevented the entire thing from coming off. I then grabbed my sidearm and sent three .45 caliber bullets into the thing's skull. Just as the imp fell dead. I heard something lower from the outside.

I went back outside and saw that the column to the left of the zig-zag path had lowered, revealing a hidden room. I went further back inside the computer room, and saw a lift lower inside the room. I ran as fast as I can inside the room, and saw a surprised shotgun guy fire wildly and miss me.

I immediately blew his head off with my shotgun, grabbed the medkit near him and stepped into the elevator just as it was going back up. I followed the darkened path to find a good amount of armor bonuses and a box of shotgun ammo. My pack was already full of shotgun shells, however. So I slung my weapons to the back, grabbed the box and found the end of the tunnel, which was actually a good height off the zig-zag path. I dropped down to the ground and gathered all the guns and ammo I couldn't bring with me into a sizeable pile inside the computer room. I took a piece of clothing from one of the dead zombie guys and lit it with my lighter. I threw it into the pile of wasted hardware and walked away.

I could still hear the bullets cook off as I went back inside the hangar exit and flipped the switch inside. It turned out that the exit was actually an elevator to the facility's nuclear plant.

As the elevator went down, I took off my helmet, breathed in deeply, and sighed, taking the filtered air in before putting my helmet back on.

"They're gonna pay for this. You will be avenged, fellas. And as for you, Chitoge, wait. And pray. I'll be back safe."
