Our fight was one sided from the very beginning, even with me holding back. Despite his cheats and many skills, he didn´t have any experience due to only getting skills through killing and even then, he only killed these weaker than him.
He was actually stronger than the limit I had set for myself but my recently perfectly integrated millions of years of battle experience made this a piece of cake. I had fun toying with him by reacting to his attacks before he even made them and occasionally even defend when he got behind my back.
Every time he got behind me to catch me off guard I defended and didn´t bother to turn around at all. I just stood there, waiting for him to come back to my front. He got really pissed by this action but still refused to come to the front and continue like a normal being, which only increased the humiliation as the fight went on.
His harem expected him to win the fight easily or at least quickly but after seeing him get humiliated they decided to step in as well.
It didn´t help him at all, in fact I would even say that the fact that he needed help from his harem only increased his humiliation even more, if that was even possible.
I started killing his girls in front of his eyes one after another and only after the third one did he order the remaining ones to flee, telling them that he was going to use his ultimate power to deal with me and that they would just get in his way.
I couldn´t tell if he suddenly decided to care about them or was just a chunni, probably the later. The girls looked at each other hesitantly but still obeyed.
Would you look at that, he actually had a trump card. Sadly for him it was some kind of powerup transformation and I didn´t want to wait for him nor did I care about the law of anime.
He was enjoying the feeling of power as he got enveloped in a golden aura when he suddenly felt a sharp pain in his chest. He looked down confused only to see his heart in my hand.
His eyes widened in disbelief. He didn´t understand how someone was able to break the 45th law of anime, especially in a fantasy world and when facing the protagonist.
In his last moments he was doubting everything he knew before everything went dark and coldness embraced him.
I grabbed his soul before it could float away. I could feel it being called somewhere that wasn´t the afterlife but that wasn´t going to happen on my watch.
I didn´t immediately eat his soul but searched through his memories, mainly because I wanted to study the foreign entity that obviously was his system.
Through watching them I gained a few things, many the information about gods in this reality and a universe that resembled my original one quite a bit and from what I could tell didn´t have any supernatural stuff. Might want to check it out, even if just for old times' sake.
At some point the System noticed that it got captured and tried to kill me with a soul attack but when it failed tried to male me its new host.
I obviously refused, so it tried to contact someone, probably its creator or another god, but I erected a barrier that cut of the signal before it could reach them. I didn´t need or want the system but was just trying to study it to make them myself, even better even.
This research wasn´t something I could do on the fly, even with my Intuitive aptitude, and might need a few hours, hours that I didn´t have right now, so I just safely stored it for when I returned to the demon realm.
The number of monsters was decreasing rapidly now that the adventures had gathered their equipment and started joining the fun. Luckily our summoners already got the thing they came for and allowed us to return to the demon realm.
You could see all remaining monsters and demons get enveloped by fire and disappear all over the town.
We all appeared back in the demon realm where we disappeared, this also meant that the previous truce has ended.
Just as we started charging at each other, a pillar of blue, fire-like energy enveloped one of the skeletons. I didn´t expect that I could witness someone get their true name so soon, I admit I was a bit jealous.
''HAHAH, MY NAME IS CARLIMAS DERA MANGOJUICE! BOW TO ME INFERIOURS AND SWEAR YOU ALIGNEANCE AND I WILL LET YOU LIFE'' the previously ordinary skeleton grew in size, obtained a badass looking armor and gained intelligence. And of course the first thing it did was get arrogant and try to build its own faction.
This was actually quite common. Monster often formed groups with named ones for several reason.
Obviously to no get killed but also to get their protections and because they would get more mana into their name bank when being summoned together with a named one.
Normally I would ignore such things or even join them but I wanted to start studying the system as soon as possible, so I just Thanos snapped them away and went to work.
I couldn´t go to my home as I couldn´t be summon there, so I just made me a provisionally but comfy cave where I would spend the next few months or even years.
