Classroom To Another World's
Demon King

Famous since ancient times when the demon race was in a land far from the other three races. Between being driven out and seclusion, they seem to do both. Past legends about the demon race trying to rule the world are not entirely wrong, the legend simply does not say that other races strive for the same. However, in the course of the war, it was the demon race that dominated the fight. The strength of their own made the other races eliminated and excluded. Then, since the rise of the power of the human race, they were exiled and isolated in their territory. There, they were led by a superpower king called the Demon King.

The demons admired the power. From the older generation to the present generation, they still have the same custom—honor those with power. It was from there that the selection of a Demon King was based on two factors, lead ability and strength. Therefore, every succession to the throne, the holder of the throne of the Demon King is always a very strong demon. It was there that the legend of the fierce battle against the Demon King was created. The fight against a demon of the level of a Demon King was always fierce.

Even with or without an army, the Demon King can do great damage on Earth. It is difficult to defeat the Demon King. If full force is sent to defeat him, then he can go and make damage to his opponent's base. Waging war with the Demon King must have scattered powerful forces. Free to have a strong sword but not with defense.

And right now, that mighty figure was before Udin and Tiana.

It's intimidating to be there. Not just the Demon King, but the royal higher-ups there as well. Udin and Tiana, the two of them were another race. Being a different race has made them feel shaky, especially if all there are royal officials. Plus, they are both weak. Each of every single individual there could kill the two of them very easily thousands of times. Their chances of fighting back were simply nonexistent.

"Is he that man?"

"Why are humans here?"

"He is different from other humans, but still weak."

There was a lot of scorn that Udin and Tiana had to listen to. They could only fall silent while bowed down with cold sweat pouring out from all over the body. Not that the demons here wanted to scorn, it was just that they were curious. But no matter what the intention, but real action often gives different results, results that do not match the estimates. Not necessarily ignoring the teacher to give him time to do his duties will end with respect to the teacher. Well, now that his intentions were just curious, every sentence felt as a scorn for Udin and Tiana.

"Lift your heads!"

Udin and Tiana heard the voice. On the throne seat, they were observing the huge figure of the Demon King. The Demon King had a large body. In the giant category. It is similar to a bipedal sheep. The morphological shape of the body is more or less similar to humans. He has a head, two arms and legs, but has a tail. Each of his limbs resembled a goat. Starting from the head of a goat with a pair of twin horns, human-like hands but large nails, and legs resembling goat feet. His entire body was shrouded in dark gray fur.

"Man, are you from another world?"

"Y-Yes..," answered Udin stammered.

He knew the Demon King about visitors from another world. One of the most frequent ways on why someone from another world can get here is when called. The Hero Summoning Ritual has been performed! From here only he understood that soon there would be strong people attacking his territory. Only, there was something that made him astonished. This is the first time someone has been hurt.

"Not to be afraid, just relax. I'm not gonna do anything bad to you."

"Good-Good, thank you." The subtle remarks from the Demon King could not change Udin's fear at all. It trembled unsteadily looking at the huge body of the Demon King. He imagined a huge overview would land on him and crumble every bone in his body. The rest, he would be a rat carcass in the middle of the road that had been repeatedly stepped on by motorists. No one will care. Most get scorn for spreading a foul smell. "When I can tell, a-what made me come here?"

"Ehm... Where did I start?" The Demon King muttered in a monologue. Voice slowly. No one in the room heard it. Then he looked at Udin's trembling body. He thought of what a weak human could do full of potential. When trained well, of course Udin will be a good dog. From here the brain of the Demon King thought of arrangements for Udin to become his partner. "First call me Gladius. No need to be so formal."

A surprising word to hear. Everyone in the Demon Kingdom had always respected and cherished their king. They always wear a call that shows a sense of admiration for the greatness of the king. But this newcomer human, a human who could not kill deer, a human who could not fight, he was miraculously given the opportunity to summon directly using the Demon King's real name. Not many demons dared to do so.

For Udin, he was not too aware of what it meant. He only thought that the Demon King was not a difficult and disrespectful person. His heart was slightly open to listen and pay attention to what the Demon King was going to say. Maybe he can take her home.

"Listen, son of man, since hundreds of years ago, my people have been pushed back many times. Our number has been declining for years. All of this is due to one race, it is the original human being of this world."

Udin surprised. But that makes it more serious. He rethinks every fictional novel story about isekai fantasy. He got a chronology of a story. What was in his mind, he thought that humans were greedy creatures. Man fights against another race different from himself. Man considers himself the best. It was from there that the human race carried out massacres against other races. The terrible tragedy of the Holocaust.

"It is not only us, the demons, who will suffer in the end if the human race wins, but the other races will also be involved. You definitely don't want the girl next to you to suffer, do you?"

"No!" answer Udin. This time it's a little loud.

"For this reason, son of man, please lend us your hand. We will help you to protect all that you love."

"Good."

Tiana and Udin, they're both unworthy of adventure.
