The terrifying reunion of the old man

"Ra-ra-ra."

In a shop in the middle of the sunset, in a sparsely populated area of Central City, an old man was humming cheerfully while looking at the system screen in front of him.

"Huhuhu, I'm getting stronger every day."

Even though little time had passed since he arrived in this world through a mysterious transmigration, the old man had still gained considerable power. This was all thanks to his erotic sales system, which made him stronger with every product he sold in his shop.

At first, the old man had a tough time. The shop interfered with others' perception and moved randomly, making it difficult to locate. This resulted in extremely scarce clientele in his first few days, filling him with anxiety about the future.

On top of that, his shop didn't actually sell "normal" products. Everything sold there was something from the system for all sorts of erotic purposes. This, combined with the shop's changing location and concealment, caused him constant stomach aches.

But as if to deny his assumptions and preconceived notions, the shop kept gaining more and more clientele who bought his suspicious and strange products. There were all kinds of people, from those who bought special stickers that objectified people to those who purchased full-scale robots, made in the likeness of fictional characters with programmable personalities. Thanks to all these sales, the old man had gained great power and felt that eventually no one could defeat him, as he exuded confidence.

(Ding!)

"Welco—?!"

Or at least, that's what he thought before seeing who had entered through the door...

"Hello, sir!"

"?!"

For a moment, the old man panicked, seeing the boy with silver hair and white eyes who greeted him cheerfully after entering, recalling his past experience due to the system's reaction.

However, believing that the past reaction was due to his lack of power to handle threats at that time, the old man tried to compose himself to deal with this. Nevertheless...

<"Know your place.">

"?!"

His attempt was completely crushed upon hearing those cold words resonate in his mind, accompanied by a colossal bloodlust that instantly transported his consciousness to a strange space filled with all sorts of beasts seemingly made of straw, coming in all sizes, along with ridiculous quantities of what appeared to be small straw dolls.

He even saw a golden one flying and radiating powerful energy next to a small armor with a sword engulfed in gray flames that made his instincts scream in danger.

"A-ah... Agh..."

But the worst part was what was in the sky, staring fixedly at him while continuing to release bloodlust like an ocean over the old man, crushing him.

["HOST, REACT!!!"]

"Haa...?!"

"Are you okay?"

Once the old man regained his senses, he tried to calm his trembling body, tears streaming from his eyes, his smiling expression frozen in horror, his mind in chaos.

<"Don't even think about mentioning what just happened.">

He heard that cold threat echo in his still-confused mind, managing to calm down only thanks to the system's life support.

"I-I'm fine!!"

"Really?"

Now driven by his survival instinct, the old man feigned ignorance, obeying the orders of that mysterious voice with all his might to please the existence in front of him, begging for it to leave as soon as possible.

"Of course!! After all, I'm so excited to see a customer!!"

"I see!"

"Go ahead! Please buy whatever you want and go home soon!! After all, it's getting dark and it's dangerous outside!! (Please, I beg you, leave and never come back!!)"

But sadly, the old man's wish wouldn't come true, and this wouldn't be their last encounter...
