Stupid guy might be the setting of this protagonist

Humans had great adaptability, but they still had a limit. It was also because Shin, who used various strong magic with ease, caused the people around him to be too shocked to say anything. Sometimes they were scared of him. After all, his talent was so shocking that it scared them, and what was more outrageous was that this guy didn't even realize that his action had caused a lot of them to be scared of him.

Haru had preached Shin several times, but he knew that it was useless since this guy was really stupid and didn't even have an ability to remember his words even though he said those words before at Shin's house together with Merlin and Melinda, which was why he invited both of them to the school as a teacher for the Ultimate Magic Research Society, after all, with both of his grandparents, someone could scold this stupid guy when his magic caused the balance in this world to be broken.

But at the same time, Haru also knew that as long as someone was strong enough, any rules turned useless, and there was no need to follow those rules. After all, they were strong, but the price of that strength was solitary.

When someone was talented, it brought pressure to the people around them, which was why a genius often gathered beside the genius. Like a Stand user who also attracts another Stand user, a genius would attract another genius.

Still, if the talented one was a male, he would become alpha and get many girls as his harem. Unfortunately, Shin didn't have that kind of alpha personality. His biggest trait was the most common trait of the harem protagonist, which was "Yasashi (Kindness), which made him a pretty boring character.

But enough of that. After all, both Melinda and Merlin were in the class to supervise Shin. Still, of course, they couldn't say that. After all, it would embarrass Shin, so they could only say that Haru invited them. It was also because of this reason that everyone was surprised by Haru and thanked him several times since they didn't expect that he was able to get both Melinda and Merlin to become their teacher.

But Melinda and Merlin didn't say much since Shin said to leave everything to him, which made both of his grandparents worried.

Shin stood in front of everyone and said, "I want to make all of you level up."

"........"

"Level up?"

"I mean, become stronger!" Shin said without hesitation.

"......" Haru, Melinda, Merlin, and the girls who came with Haru before wondered whether this guy really had Alzheimer's disease. After all, they had an important conversation a few chapters away before, but this guy had already forgotten about their conversation.

"There have been a string of strange incidents lately, right? We've managed to get through them, but I think we should get you leveled up to be ready for the next things that come along." Shin explained to everyone.

"That makes sense. It's not as weird an idea as I imagined," August said since he knew that Shin often thought something strange.

"Hey!" Shin felt slightly hurt at that moment.

"So, what are you planning to do, Shin?" Haru asked directly.

"Have you all become proficient with a certain level of attacking, defensive magic, and enchanting magic," Shin said.

Haru, Merlin, and Melinda nodded and thought that this guy was more normal than they had thought.

"How about we start by checking how much magic power you can control?" Shin asked.

"Magic control? Why?" August was confused.

"Why? A higher level of magic requires appropriate magic control, right?" Shin said.

"I thought a higher level of magic required devising chants and more precise visualization," Thor said.

"No." Shin shook his head and said, "To use magic, the first thing you need is magic power, to act as fuel, and to use higher-level magic, you have to be able to control enough magic power, or else..."

"........"

Shin stopped since he could see that no one could understand.

Haru could only shake his head. After all, there wasn't any fuel in this world, but he didn't intend to refute anything. After all, his setting was someone from this world. Still, even though he had said that he was coming from this world, he wondered why Shin didn't doubt his words at all, and because of this, he thought that this guy was really gullible. He was sure that Shin's type of guy was someone weak against pressure, and he was sure that when an aggressive salesman came to him, this guy would buy the useless things that were sold by the aggressive salesman.

Shin knew that everyone was clueless about his concept of magic, so he explained to everyone and showed them an example. "Please gather, everyone." He then looked at August and said, "Aug, can you conjure up a barrier magic for us?"

"Oh?" August was a bit surprised, but he nodded. "Okay." He then raised his palm, and a light green barrier like a shield appeared in front of his palm. The size of the barrier wasn't big since it only covered the top of the head until the ankle, but he didn't think too much.

Shin then observed August's barrier magic and shook his head inwardly. He then flicked August's barrier, causing a "ting, ting" sound so thin that it might crumble anytime. "This won't do. This barrier is too thin. This won't defend against most of the magic."

"Eh?!" August's face blushed. After all, Shin said those words to everyone in this place. His status as a crown prince, but Shin said those words without hesitation, which made him lose face, but after all, there was both Melinda and Merlin here, so he couldn't complain, but more importantly, he clenched his fist and felt unwilling at how weak he was.

"Then, Shin, can you show us your barrier?" Haru asked since he didn't expect Shin to be stupid enough to say those words to August right in front of everyone. Even if August was really weak, this guy was still a crown prince, alright?

"Alright." Shin nodded, then created a barrier, but his barrier was different from August's since there were two layers of barrier around him, which caused everyone to exclaim. "Due to my visualization and my control over magic, I can do this."

Everyone was in awe, except for Haru, Yuri, and Lynn, after all, Haru had taught them a lot of things, including barrier magic, so if someone asked both Yuri and Lynn who was the strongest barrier magic user then, without doubt, they would say that it was Haru.

Then Shin explained that Oliver made a barrier with pure magic power to block his attack that made him full of sweat and told them the importance of control over the magic power.

"With enough magic power, you can defend against magic well enough with just a magic barrier." Shin then looked at everyone with a mischievous smile then asked, "Do you want me to show you a portion of a magic power I can control?"

"Wait!" Melinda and Merlin quickly wanted to stop Shin, but...

Shin then released all the magic power on his body, causing everyone to feel the horror of his power!

Haru frowned at this guy since this guy really loved to show off, right? He then stood up in front of the girls, and the girls overwhelmed by Shin's aura suddenly felt at ease.

The girls then looked up and saw Haru standing in front of them, blocking Shin's aura, which somehow made them worried, and at the same time, they felt very secure with him in front of them, though they also felt annoyed by Shin at this moment.

"SHIN, STOP!!!" Melinda roared.

Hearing his grandma, Shin quickly stopped and smiled helplessly.

The guys couldn't stand on their feet and plopped on the ground tiredly since Shin's aura made them unable to breathe, and the girls leaned on Haru. After all, that pressure caused them to be very weak.

Only Haru, Merlin, and Melinda could stand up without trouble, but both Merlin and Melinda also felt overwhelmed by Shin, and they knew that their grandson had become stronger than both of them.

Well, in truth, Yuri and Lynn also could stand up, and even though Shin's aura was powerful, it wasn't enough to make them feel overwhelmed, but they needed to pretend to be weak. After all, they wanted to be spoiled by Haru.

"You two, alright?" Haru asked both Lynn and Yuri.

Yuri and Lynn showed an aggrieved expression and leaned on his body so Haru could support them.

This caused Maria and Sicily to feel jealous, Olivia sighed and understood why Haru was popular, and Alice somehow realized the feeling between a man and a girl.

"If you can't control that kind of magic power, you won't get anywhere, so with that in mind, we're going to practice magic control every day," Shin said with a smile.

"......."

Somehow they wanted to beat Shin, who was smiling at that moment.
