The Demon World, the world where demons reside. The king who rules the Demon World is the Demon King. However, many years ago, the Demon King mysteriously disappeared, leaving the Demon King's throne vacant for a long time.
At this moment, above the juncture of the Demon World and the Human World.
"Hey, old man, where are you taking us?" Shesi Suzuki asked the demon who was carrying him in one hand and his younger brother, Iruma Suzuki, in the other.
Iruma, beside him, tugged at his brother's clothes, wanting him to be more polite. After all, they had already been sold to this demon. But Shesi didn't pay attention to his younger brother.
Seeing that the old man didn't speak, Shesi scoffed and then fell silent. Originally, he and his younger brother were working on a fishing boat. That day, there were huge waves at sea, and the frozen tuna in the cargo hold were crashing around. Shesi and Iruma were assigned to go inside and stabilize the tuna. You might ask if this is a bit absurd—why would they be sent into the cargo hold to stabilize tuna? Sorry, Shesi and Iruma are both only 14-year-old minors, and they didn't come in through proper channels; they were sold by their parents. So, the boat couldn't have been a legitimate one either.
Speaking of his parents, Shesi gritted his teeth. He had never seen such irresponsible parents. If he hadn't been a transmigrator with a system, he really wouldn't know how he would earn money to pay off his parents' debts while also taking care of his younger brother.
Thinking of this, Shesi sighed and then recalled the encounter on the boat. Actually, Shesi was somewhat grateful to this demon, because if it weren't for him, his younger brother might have had his head split open by a frozen tuna 'holy sword' sliding down from above.
Finally, after flying for a while, the demon seemed to say something. When he realized Shesi and Iruma didn't understand, he lightly tapped his finger.
"Hello, both of you. Let me introduce myself. My name is Zoffy, the one who killed Ultraman... *cough* My name is Sullivan. This is the Demon World. Your parents have already sold your souls to me."
"We already know! You don't need to repeat it!" Shesi didn't know why, but he suddenly understood the demon's words, but still interrupted him. What a joke! They already knew the other party was a demon, so why bother with a good tone or fawn over him? Demons wouldn't fall for that, at least in Shesi's understanding.
Shesi was a bit anxious. The abilities granted by the system couldn't be used on this demon yet, which was the most troublesome part.
"What a short-tempered child," Sullivan said, then ignored Shesi. Soon, the three arrived inside a castle.
The scene shifted, and Shesi and Iruma appeared in two chairs, wearing new, suitable clothes.
"Will you be my grandchildren?" Sullivan knelt on one knee, holding Shesi's and Iruma's hands, one in each.
Shesi stared at the scene, his mind blank for a moment, then he remembered, Iruma Suzuki, Sullivan... Wasn't this the anime he had watched in his previous life?
He hadn't thought about it before, after all, the repetition of Japanese surnames was too high. Murakami, Murashita, etc. Recalling it, ever since he and Iruma were born, they had been 'cared for' by those parents, receiving the harsh realities of society from the age of one, being used as bait to catch tuna... At five, they were left to fend for themselves in the mountains, chased by bears. At that time, all he thought about was how to survive using the system's abilities from his transmigration and how to take care of his younger brother.
Thinking of this, if it really was the Iruma anime, it meant that their tumultuous life should be coming to an end. Thinking this, Shesi couldn't help but let out a sigh of relief, and his tense nerves relaxed.
And Iruma, next to him...
"Eh? Eh?!!!!"
Sullivan continued.
"Actually, I'm a lonely old man. I've always yearned for a grandchild."
"Grandchild?" Iruma was even more confused.
"That's right, I'm so envious of Levi and Belial. They always boast about their grandchildren. I'll buy you anything you want, and I'll spoil you rotten. Come on, come on, please?" Sullivan continued his plea, constantly looking back and forth between Shesi's and Iruma's faces.
"Ah... my brother and I seem to have been sold..." Iruma still wanted to say something, but Shesi directly interrupted him.
"Okay."
Shesi looked at Iruma with a 'hate to see him fail' expression. It seemed he had protected Iruma too well all these years. At this moment, Iruma still wanted to say that they had been sold to him. Seeing Sullivan's appearance, Shesi was basically certain that this was the anime world from his previous life, so he simply agreed to Sullivan.
"Really?" Sullivan first jumped up in surprise, then looked at Iruma with a crestfallen expression.
"I will respect your wishes. If you don't want to, you can refuse. But! That's precisely why I will wholeheartedly beg you. I really want grandchildren. Ah~ I want grandchildren so badly. Please, be my grandchild! Please help this old man... Fulfill this small wish of mine, Iruma-kun!" Sullivan instantly transformed into a smaller version. Shesi was a bit surprised by this scene. Although he had watched this anime in his previous life, it had been so long that he had almost forgotten everything. Could demons in this world change their size anywhere?
A phrase suddenly appeared in Shesi's mind: 'Himouto' (Demon World version). Shesi looked at Iruma beside him. After Sullivan made the request 'help me,' Shesi knew that his younger brother probably couldn't refuse it.
Iruma, being a good-natured person, for him, Sullivan's 'help me' + request = taking on the task = cannot refuse.
Ultimately, Shesi and Iruma still signed their names on the contract.
"Becoming... a demon's grandchild..." Iruma felt a bit dreamlike, wondering how he had become a demon's grandchild. "Well, since that's the case," Sullivan snapped his right fingers, and the clothes on Shesi and Iruma instantly transformed into school uniforms, and even the room changed.
Shesi and Iruma looked at Sullivan in surprise. Shesi couldn't help but marvel in his heart, 'Magic is really convenient.'
"After all, you are my grandchildren, so we must be fully prepared: clothes, food, accommodation, and... education!"
Sullivan then said.
"You two have been wandering with your parents and probably haven't had a proper education, have you? But don't worry, Grandpa has already completed the procedures for you. I am your grandfather~ The word 'grandfather' is truly wonderful."
Shesi looked at Sullivan, who was still muttering to himself.
"A demon school?"
