Many pedestrians crossed the street as part of their daily activities on a hot day.
I was walking leisurely among them, wearing office clothes.
Without realizing, someone sent me to a dark pitch dimension in a flash.
Even so, I wasn't surprised at all because it wasn't my first time visiting here.
A woman with long straight white hair wearing a black dress then appeared and walked with a scary aura.
"Oh my, I have been waiting for you, Hiroki. It seems like you have been used to coming here."
"Obviously. I won't forget this place no matter what."
"Glad to hear that from your mouth."
"Why did you send me here? Can't we meet in the office like usual?"
I used to work at the company Boss formed.
"We have no more time left just doing unnecessary things."
"This time what is my mission, Boss?"
"Can't you just call my name properly here?"
"No, I can't and I won't. I don't like calling you Nemesis. It's weird for me."
Who would have thought that my boss actually was the Goddess of Destruction, Nemesis.
I couldn't believe that I was working under her command until now.
"Alright, I want you secretly join a new game. It is set in a new world God created recently. You must be familiar with it. It's been trending in the Realm of God these thousands of years recently."
"So it's about isekai, huh. Well, I am familiar with it. I can't believe Gods who have eternal life are so slow to recognize it. Hasn't it been trillions of years since that war?"
"It can't be helped. Gods are staying in their dimension too long just like hikikomori or NEET."
Isekai...
The story started when the protagonist was sent by God to a different world.
There were many options to send the protagonist to the other world actually, but there were only two options in general.
First, reincarnation.
It started when the protagonist died, then would be reborn with a new body.
God then sent the protagonist right after that.
Usually, a reincarnation would lose all memories, but God made an exception citing the current trend.
But, there was a side effect of keeping the memories that way.
It would damage the protagonist's soul.
In the worst case, the protagonist's existence would be erased.
I couldn't believe that Gods were still using it that way.
Second, summoning.
Summoning actually could happen anytime and anywhere.
Protagonist who was summoned to a different world wouldn't lose body and memory.
But, the protagonist would get in trouble when meeting native from that world.
Even so, God gave that person the language barrier skill to communicate with them.
Protagonist required to learn that skill manually, but God forced it by damaging the protagonist's soul.
Gods must stop spoiling their protagonist.
They must follow how the concept actually worked.
After all the explanations, I asked Boss.
"Then, why should it be me?"
"It looks like you have nothing else to do after successfully snatching that pitiful man's ancient artifact."
"Do you mean Zack? It was just a coincidence."
Suddenly, a black cube patterned with purple lines appeared.
The cube had consciousness itself.
Based on the information, the cube was an ancient artifact that could kill the Gods and stopped Gods of war trillions years ago.
The cube then disappeared in order to search for a new owner.
Somehow, the cube chose me as its current owner after leaving Zack.
I just happened to pick up the cube when he let his guard off, I didn't know the reason why it chose me.
Boss said that I was chosen for having better compatibility than him, but I completely didn't understand the selection process.
I felt sure if it was some sort of mary sue or deus ex machina that every protagonist had from the author.
People would hate underhanded conditions like what happened to me.
"As you said, but this time I don't want you to be the hero who'll save or demon lord who'll destroy that world."
"What do you mean?"
"I want you to act as an observer just like Gods, but more actively there since they don't let me join their game."
"Hehe, what a pity God. Looks like they still don't want you to ruin their fun."
"That's why I will send you there to surprise them."
As expected, that was Boss' true intention after all.
As a God that was hated by all Gods, Boss wanted me to beat their game in disguise.
A woman with long straight red hair wearing a medieval-style outfit came through God-level teleport.
"Feina, huh."
"Wait, don't tell me she is another clone after Reina."
"Exactly. Feina will be your partner this time. Reina is still busy on working."
"You're relying too much on Reina."
"You're not wrong either."
There was nothing impossible for God.
They could do whatever they wanted.
Boss could make as many clones as possible even if they have different personalities.
In my perspective, clones felt like making children, but without fertilization.
"If she finds me out with another woman, she will definitely kill me. Anyway, when we start our-"
I was sent to a different world in a flash with Feina.
We suddenly were in a forest at night.
"Sorry, I forgot to introduce myself. My name is Feina Scarlet."
"My name is Takagi Hiroki. You can call me Hiroki. By the way, are you a demon?"
"Of course. Look at me closely."
Demon was a middle-level existence that was one step behind God or to be exactly it was called Demigod.
It had a couple of horns on the head, a couple of wings in the back and a tail in the butt.
Even so, the demon wasn't the only one Demigod existed.
God was a high-level existence where the body and soul were merged with an infinite amount of energy.
God could change the appearances at will.
The cube disappeared since there was nothing else to do.
Suddenly, I heard someone's voice.
"Big brother."
As I turned around, there was already a high school girl with short black hair.
She was still carrying her school bag and wearing her school uniform.
"You must be kidding right now."
"Eto… Big brother?"
"Sorry, Yui. I didn't mean to ignore you."
Yui used to be my little sister even though we were not real siblings.
I was still in high school and she was still in elementary school when our parents remarried.
Unfortunately, they were dead in an accident a year later.
Yui asked me.
"Where are we? Then who is that woman? Are you cheating again behind Ms. Rena, big brother?"
"We are in another world. This is Feina. Of course, I'm not. How many times should I tell you?"
Feina interrupted our conversation.
"I don't want to ruin your family meeting, but we can't stay here too long."
"Come on Yui, come with us."
"Yes."
"Wait a minute, you have something to do first."
"What should I do?"
"Your clothes. Are you forgetting about our mission?"
"Sorry."
Feina changed my clothes and Yui's clothes through creation magic.
It was a kind of magic that required the ability of the user to materialize things.
She also turns herself into a human completely.
Yui was amazed to see how great the she was.
"Wow, you're amazing."
"Thank you, eto...."
"Yui, Takagi Yui."
"Ah, Yui."
Three of us then walked to get out of the forest.
In the middle of our journey, we saw the forest was burned by fire.
"What should we do now, big brother?"
"Yui, stay here with Feina. I'll go check first."
"I'm counting on you, Hiroki."
When I came closer, there was a burning of fire that went towards me.
"Big brother!"
"Hiroki!"
I thought I would end up in a tragic way by dying here.
