I confidently walked into the security room and before the door was even slightly open, dumped 10 nails into the room through the thin door.
I heard the screams of the victims from within and chuckled a little. Of course they wouldn't die from just this, so I took out the hachet from my trousers and split the skull of the first enemy who made himself visible.
My mind entered blind rage, my heart beat violently and every part of my being was allocated to the act of killing.
The last guy tried to reach his gun, but it didn't matter. Before he could aim the gun, I threw the hatchet to his face, splitting it wide open.
By the end, in the bloodied room, I was the multicelluar living thing, surrounded by gory corpses. I was feeling great! Like I breathed in fresh air after a long time of suffocating.
I quickly went over to the control panel of the security cameras and killed all the cameras. Then, I took the guard's guns, ammo and loaded a new magazine.
"Finally... a fucking gun!", I audibly said.
'Goddamn, I missed this feeling of death being in my hands!', I thought as I left the room, all bloodied.
The gun was silenced so I didn't need to worry about shooting anyone or anything that came across me.
As I walked over to the building's gas distribution room in the basement, I suddenly came across a few other guards. I of course shot them in the head before they even knew I was there.
I reached the pipes and planted my homemade explosive. It's not lethal by itself, but the magnesium in it burns so hot it can melt the gas pipes and ignite the gas. It's a two-stage explosive, the first for melting the pipe and the second, which waits for the gas to mix well with oxygen for maximum burn.
I set the timer for two hours, changed my clothes into one of the dead guards and left the room. It seemed there were some people who discovered some of the bodies and had called for reinforcements. When I spotted the people who had done so, I blended in and pretended to be a guard and shot them in the head whenever their guard went down.
By now, I had killed over 20 people in just half an hour. I was going to kill so many more tonight...
I made my way into my room, where Aoi was sleeping because of the drug I had given her in her water.
I quickly showered, disposed of all the filth on me and woke Aoi up.
"Honey... Honey, wake up.", I squeezed her fluffy cheeks.
"mh.. hm...", she groaned.
"HONEY!", I yelled in her ear.
"KYA!", she jolted awake.
"We need to go.", I instructed her.
"Huh... Huh? Now?", she asked dazed.
"Yes, now! Hurry! Get dressed!"
She quickly put on her clothes and we were both on our way out.
I had already taken care of the reception people, they were all dead and I hid their bodies under the table. Aoi didn't know it, but she walked past 13 dead bodies that day.
After we left, there was about a minute left on the explosives.
I stopped Aoi and told her to look at the building.
All of a sudden, from the base of the building, all the way to the top, a massive wave of pure blazing inferno shattered all glass and scorched the paint away.
She almost fell; she was so startled.
The screams of people soon escaped the burning building. Alarms went off and people all around gathered to watch the spectacle.
I was grinning ear to ear, feeling as giddy as a summer child.
Aoi took a short glance at me and her face went pale.
"Di... did you...?", she stuttered.
"Haha! Yeah!", I replied in a child-like tone.
She was visibly horrified and instinctively backed away from me.
I grabbed her hand tightly and prevented her from going anywhere.
"Le-let go... Let go!", she struggled.
"No.", I said in a crazed tone.
'This is it... It's over... I won't be able to control it anymore... let's just kill her... And then, I'll kill Takeshi... And everyone else... Kill... kill kill kill kill kill kill kill kill KILL KILL KILL KILL KILL KILL KILL KILL KILL!!!!'
We were in a crowded place but I didn't care. I took out my gun from my waist and shot her from underneath her jaw.
The bullet pierced her brain and she was instantly dead.
A wave of euphoria washed by me. Yes... this is what I am... A fucking serial killer...
I let go of her limp body and vanished into the crowd.
