Demon’s Training?

The places takes to the secluded places which no persons usually passes by. Despite being secluded, it was spacious. as for the reason why people usually don't pass in this place, that's because his place is dangerous.

One can encounter an man-eating earthworm, while some can encounter man-eating spider. Everything here is man-eating!

In that secluded places where the surrounding was filled with tree—nature, there existed 1 group of person although the group only contained 2 members. First one was panting heavily with his face red, while the other seemed fine.

but, that person was still letting out a noise, that is forbidden to mention.

"Haah~ haah~, Ayame-chan, I can't go on for anymore... I've let out so much..."

"Then... do you... want to... quit?"

The Oni let her breath out aggressively while slowly speaking to Kuro.

"...no!"

Kuro right now, was trying to empty his mana pool as much as he can because he was interested in Demon's Exercise. Apparently, the person who made this exercise was the Demon King: Treiner and it can be used by humans.

Although no humans really trains it because, it was not taught to them. Even if they managed to steal the books from his castle, almost no human could read Maoul and the books was written in Maoul. so, the only way to be able to train it was get taught by someone or find someone who can read the book.

1 hour ago

Both he human and the Oni was walking toward Agrenoria because they've stayed in the forest for to long. Even if Led was currently not in Orphanage, some would have think it weird and may even accuse him that he is working with demon, though that doesn't matter.

but at the same time, the adorable Oni in his next suddenly reddened her eyes after she got out of her dozes. Afterward, she ran really fast that from 17's judgement, she went back to Agrenoria and to his place with this instant.

Running 1 lap, seemed to cool her off and she stared to Kuro with her face red unknown if it's due to blush or it's because she ran a far distances.

With a tinge of sweat in her forehead, she said to Kuro while her horns has began to emerges.

"Kuro-kun~♡ are you interested in demon's training?"

Suddenly asked that, Kuro was too dense to notices her strangeness and 17 or 21 didn't bother saying anything. so, he innocently accepted the hell training.

That was the gist of it.

***

Kuroks mana was reduced to absolute minimum, barely to the point that he wouldn't faint, but it didn't prevent his dizziness, and he felt like vomiting but he endured it.

"That's enough. Let's try the next step!"

Hiding her surprise that Kuro managed to empty his mana to the minimum condition that he won't faint, and actually enduring it, she suggested Kuro. at this point, she would accept it if Kuro said he will give up.

Because this training wasn't supposed to be tried by children whose age not even passed 5, and she only suggested this training out of prank.

"... I'll, do... it."

This feeling was weird for 17 and 21. Why did having less mana gives them so much suffering when they had no mana in first place. This place truly gave an weird effect to their body.

The Oni nodded after seeing the child's weird determination and curiosity.

Opening her palm, she formed something out of mana. It was meant to be hold by 2 hands but it's didn't look heavy...

'Wait, what? Jumping Ropes? Demon King actually trained through Jumping Ropes? Haha! That's a twist(21)'

'Don't underestimate Jumping Ropes. It is one of the athletes where you can train your body without moving from one spot. Not only does it trains your feet, it will also train your overall bodies. Besides, it's also the athletes that heavily defies on gravity so... which means...(17)'

Whilst 17 was explaining to increase the words count, Ayame has started demonstrating the training.

At first, normally jumping. Then, moving her feet, she seemed actually running but not moving at places.

I, it's not jiggling! Kuro has sigh in relief that she was in her child form. If she was in her adult form, even not that much, she still had it. and for 'it' to not jiggles, one had to be the 'wall' itself. The kind of 'wall' that could kill you just by mentioning it...

I am sorry Ayame-chan. I wasn't concentrated enough.

Kuro who felt the stares of the Oni who were still jumping, apologised to her.

This time again, she changed her jumping way, while jumping she swung her arms inwardly as the ropes' trajectory danced around the air and when it landed to the ground, it emitted an beautiful sound as it flew to the air once again.

Finally, she jumped a bit higher compared to before as she puts more strength in swinging the rope making it travels between air and ground 2 times before she lands and jump again.

"How is it!"

After doing all sorts of stuff, she looked toward Kuro, not forgetting to put the smug faces in her.

"That was amazing..."

While watching her, the mana was going inside him, slowly recovering but he prevented it from happening so, he was still dizzy.

"but, Ayame-chan... I don't have a mana to form the ropes..."

Slightly panting, Kuro said to the Oni who still had the smug face.

"It's okay. You can use mine."

'My instincts! Calculate it! From what degrees, what timing, for how milliseconds long do I have to hold the ropes for our hand to touch!(17)'

'That's right! Do it! Do it!(21)'

What, is wrong with these guy? They were supposed to feel the similar experiences, feeling Kuro was feeling. That meant, these 2 should be equally tired to Kuro. It was already amazing that they still could jokes around.

Nevertheless, his hand still moved as 17's instincts, and touched Ojou's hands which was warm.

'F*** it. Whilst at it, I'll enjoy it.(4)'

''Child is not allowed to use insult.(17)(21)''

Ignoring them, while panting lightly with eyes half-closed, he stayed at the same spot. Because of how he looked, he was safe from more pranks from the Oni. Kuro could not care less because of how tired he was.

Then, finally moving, he swung the jumping ropes, which he defied the gravity by jumping...

*thud*

Along with the sound of something falling, Kuro's feet was entangled with the mana jumping ropes and he fell from his faces.

"Kuro!?"

Kuro were too weak right now that he couldn't even be considered as cannon fodders in the wars. at best, he could make use of his intelligent to crush one countries by commanding using the so-called strategies.
