Circling around my head like a revolving lantern were the memor…memories of my original world? Actually, it seems that I don't have many.

"You're one of those classmates I've forgotten about or whatever. I don't remember you, but I do remember that I forgot about you. Something like that?"

"Damn it, why? Now that it's come to this, I'll unleash as many trump cards as it takes against you! An incompetent like you!"

He was reluctant in wasting his precious skills, which he had a limited number of uses of, in order to kill me. So, he was racking his brains over how to accomplish the task with the minimum number of skills. Though it seemed that it was best to keep the invocations for powerful skills up his sleeves in case of an emergency, he had already run out of options.

After all, neither her nor I play a leading role in this parallel world…yet even so, we were going to do just that on behalf of our classmates. Since there's a valueless, nameless supporting role companion in the midst of the killings, yet they act like a protagonist, doesn't that indicate an error in the calculations? If the end result is wrong from the start, then didn't the calculation process go wrong somewhere?

This is not an equation that will result in him being the strongest. This is the end, the equation's solution.

"Goodbye. Whoever you are…"

The act of killing a classmate who wanted to be invincible by copying all sorts of skills. As he raised hell, protruding swords, invoked skills, and fired magic continued to tear and destroy my body. However, he screamed like a crazed madman.

"Why?! This is absurd, it just isn't right. You should have been killed many times over by my calculations! Just die already!"

In a world of swords and magic, mathematically-calculated and reliable skills can combine with attacks that hold a high chance of finishing someone off, creating an inescapable multi-attack. Like I said though, it was pointless. There's an error in the calculation. Well, I suppose it's just bad lack.

"I have no need for your leftover, shoddy skills, disappear! Stop kidding me!"

He bore a grudge against me, playing the waiting game while holding skills that were 100% sure to kill me. He continued to make the most effective, perfect attacks according to probability theory. I wish he could just fire everything. If he did that, at least it would be over without dying right now and I would be the one doing the killing.

As his complacency kept dwindling, he was struggling to put my body out of order through his manipulation skill. My body has already gone out of order a long time ago, you know?

He glared at the stick of wood I was carrying above my head, not able to understand. Even with his cheat-like sword, he couldn't kill me, his prideful magic shield was torn up, and the magic he continued to fire was nullified. Seeing me about to swing the wooden stick downwards made a display of how incomprehensible things are after coming to this world and how calculations have no meaning. This other world is always full of nonsense, so in that case, they certainly can best your calculations, right? Whoever you are.

While firing his deadly multi-attack skill towards me, he groaned "Guh," in annoyance as he destroyed my body. I only have shoddy skills which aren't worth stealing, and it seems he'll suffer a heavy loss of precious skills by trying to kill me. With this, he's exhausted his cheat skill that snatches other classmates' skills by killing them. And even then, he wasn't able to kill me, making it a heavy loss.

Everything from my left wrist and up was gone, my elbow was broken, left to dangle, my face also seemed half burnt to a crisp, and that technique just now cut off my foot, but even so, I kept walking. Seeing that, he opened his eyes wide while blankly starting, only letting out a mumble.

"Monster…"

It seems that I became a monster after being indecipherable. He couldn't find any answers using his prideful calculation ability, which in other words means that he couldn't comprehend the meaning of the deceit going on.

For mathematical geniuses, a world where 1+1 doesn't always equal 2 will treat them like fools, and their probability theories will definitely fail. This is a world where the dice will roll an "M," you see. Anything other than 100% can mean 0%, and at the same time, anything can happen if the probability is above 0%.

He's a genius who can calculate the right answer in an instant, so I have to cut off his chances right from the get-go. Taking measures, I foiled his moves, crushed his preparations, watched out for traps, tricked him, fooled him. His chances turned into chaos by the middle stage, and made the outcome of the endgame simple. Then, his simple calculations on how to kill me no longer worked in the endgame. I became a monster by that point and his probability-thinking ability was increasingly reaching its limits.

His calculations were infinitely increasing, and when he tried to work
