I’m the only programmer in a different world~ The knowledge of my previous life, reincarnated and revived, is demon king class. I was abandoned by my family, but I feel like the law of the world liked me. Even if you asked me to come back, it would be too late. Strongest matchless with programmed spells~

　I decided to watch a mock battle between Myra and Seren.

　Myra moves a little and dodges the fireball homing projectile fired by Selene.

　Then, measure the distance and block the guided bullet with the barrier magic tool.

　Fires guided bullets of electricity with a magic tool.

　I made a magic tool for barriers and guided bullets and handed them to Myra in advance.

“The barrier is cunning. Our attacks won’t hit.”

“I’m not sneaky. The rules allow the use of magic tools.”

“Ugh, it’s cracked”

　Selene was hit by an electric shock, and the battle seemed to be over.

“Thank you for your hard work.”

“Lend me that barrier magic tool.”

“Okay, I’ll lend it to you.”

“Tight, you don’t love me anymore.”

　Did Myra see another play?

“That’s not true, honey. A fair game burns.”

“It’s love only when it competes. And then it burns up.”

　Myra and Selene started a mock battle again.

　Myra fires an electric shock.

　It looks like Seren activated the barrier, but it’s in the wrong direction so it can’t be blocked.

　That’s because it’s not an omnidirectional barrier.

　Selene’s gray hair stood on end under the influence of electricity.

“Ugh, that’s terrible. My hair is all messed up.”

“The bristling fur suits a thief cat.”

“It’s good to put your hands on the ground. It will remove the static electricity.”

　Selene puts her hands on the ground.

　andcombCombI took out my hair and started arranging my hair.

“Guys, you’re doing it.”

　The student council president, Anode, and her younger brother, Cathode, have arrived.

“Are you practicing too, Anode?”

“Oh, I was thinking of training my little brother.”

“Myra, Seren, please make room for me.”

　The anode and cathode face each other.

“[Water polo launch]”

“[Water Shield]”

　The two are fighting using shortened chants.

　Is this what it’s supposed to look like?

　Guard the water ball flying in a straight line with a water shield.

　If you’re going to guard, a stone shield seems solid.

　But it gets in the way after I take it out.

　Since you can’t see the barrier, it’s not very convenient to use.

　Wait.

　Isn’t a wind blade perfect for assassination?

　You can’t see it, so it’s hard to prevent.

“No one uses wind blades.”

“That’s right. Because it doesn’t have any power.”

　Seren replied.

　Well, I used it to dismantle King Wolf, but it worked fine.

“Try it lightly”

“Fine. [Fly, blade of the wind]”

　A breeze hit my face.

　Eh, that’s all.

“Won’t it ever break?”

“You can’t do that.”

　How was I doing?

　I was imagining a vacuum blade.

　A ball of air can’t cut it.

“What do you think will happen when there’s no air?”

“It can’t be helped.”

　There is no concept of vacuum.

　I think the vacuum was discovered on Earth in the Middle Ages.

　Probably later than Sekigahara.

　In Earth’s history, when there were guns, there was no concept of a vacuum.

　This world doesn’t seem to have any gunpowder, so it’s probably behind the medieval times in terms of science and technology.

　Reason allows you to get a high score on the truth test.

　Is even the concept of combustion in danger?

“Can you explain what kind of phenomenon combustion is?”

“It catches fire and burns things. There’s also smoke.”

　Wow, I don’t understand the oxidation phenomenon.

　Not only programming knowledge, but also general scientific knowledge is terrible.

“There was a question on the entrance exam that asked you to write what is necessary for a fire to burn.”

“Yeah”

“How did you answer?”

“I answered flammables and sparks.”

“I answered temperature, oxygen, and combustible materials.”

“I’ve heard of the theory of temperature and combustion, but that theory is in the minority.”

　Oh, oxygen hasn’t been discovered yet?

　Come to think of it, I wrote the word oxygen by combining the words “acid” and “moto.”

　Wow, I might have been thought of as a chuunibyou or some weird guy.

　Yeah, when I think about it, it’s a miracle that I was able to get top spot.

“Taito, you look difficult.”

　Myra looks into my face.

“Nothing”

“If you have a problem, tell me.”

“I also want to hear about the president’s worries.”

“Apparently I’m a monster”

“Tight is tight”

“What are you talking about now? You invented a barrier, right? I know it’s not normal.

“It’s definitely not normal.”

“If you’re worried, you can aim for a demon lord. I tell myself that if I hit a wall, I will definitely become a demon lord.”

　What is a demon king?

　Are you going to slaughter humanity?

　Come to think of it, there was the Demon King Study Group.
