Teacher Maou

"Hey, Maou." Kuro began the conversation.

"What is it?"

Kuro continued after confirming his response. "What is the difference between human' technique and demon's technique? By technique, I am talking about their physical fighting technique that's not related to mana."

Maou hanged his mouth slightly to Kuro. "Even you have an interest in martial arts? Alright. Firstly, you're misunderstanding something. Everything is related to mana."

"The air we breathe is mana, our body is made of mana. Our action is also mana. Basically, everything is mana. Although, the density of mana in each area is different."

"Heh~ so bigger mana density means stronger power?" Kuro nodded at what Kuro said.

"That's not quite right. Although our body is made of mana, it's not just mana, and mana is just something to supports things. In the end, what matters is our physical body for stronger power."

'So sciences still works, at some point…'

Kuro began to question more. "In the end, what's the differences between demon and human's technique?"

"The demon techniques revolves around controlling the force released outside the body, while human's technique revolved around controlling the force inside the body, to release the force more strongly."

Maou drew 2 stickman in the air. Both the stickman was in punch motion, and Maou wrote the flow of force with arrow symbol.

The left one's arrow symbol was outside the stickman's fist, but the arrow symbol was written in rotation matter, as if it was making an spiral, or the force is spreading out.

The right one, while the arrow symbol was inside the thickman's arm, the symbol was bigger. But the flows of forces was straightforward.

"What happen if you combine the human and demon's technique? Why have no one ever done it?" Kuro questioned to Maou. There's no way no one have ever thought of it in the 5,000 years.

Maou sighed strongly to Kuro's question. So strong that it made Kuro felt that he askde something really stupid during the interviews. "First of all, a person like you who can speaks 2 Major Languages are rare."

"Moreover, being able to speak 4 major languages is unheard among the human, although it's an easy deal for mythical creatures, seven deadly sins, or me."

"Secondly, even if you can speak Maoul to ask someone to teach you demon technique, I doubt you can find someone as willing as your girl."

Kuro smiled like an idiot. "Hehe~♪ did you just my girl? I am flattered~♪"

If Maou wasn't there, he would be dancing right now out of happiness, like an idiot…, no, an idiot.

Maou was beginning to lose patiences. "Third, combining 2 or more technique is something ridiculous. Moreover, combining 2 techniques from different races. That's just looking for a way to suicide, or make yourself a disabled person so that you won't be able to move for the rest of your life."

Maou did his usual thing and drew the thickman.

The attack motion was about the same and the arrow symbols was inside the thickman's arm.

Then, the arrow symbol cracked and finally broke. The force without even a chance to flow outside went berserk inside the thickman's body, breaking it from every direction inside.

"That's amazing! Now that you say it like that, I admires Garou for combining all the martial arts he learned." Once again, Kuro's eyes shone brilliantly. (If there's a light in Kuro's pupils.)

"As you can see. Controlling a force is hard by itself and just a normal demon technique have a risk of harming your own body. Combined with human technique to amplify the forces, it's no doubt that the forces will go berserk inside the body. It's close to impossible to combine 2 technique or more, and the difficulties to do that surpass the difficulties to learn the technique of 4 Great Grimoire Kingdom's Mana Zone, and possibly reaches the difficulties of Mana Domain"

Once Maou completed his long sentences, Kuro sweated. "Haha… this world's combat system is surely broken. Can you tell me more about the combat system? What's there in it?"

Maou paused. "Wait a minute, what do you mean by Garou?"

Kuro smiled to Maou. "It's Garou from One Punch Man. By the way, does this world have a print?"

Maou wasn't as quick to catch on what Kuro was, nor did he have any intentions to read his mind. "There is, in Reign Empire."

Kuro made a guts pose. 'Finally! Something that exists that I don't have to make myself.'

Maou was still unsatisfied. "So what's Garou? Tell me quicker!"

"You'll know later or later, maybe in 6 years, when I am free? By the ay, quickly tell me more about the combat system of this world."

"You're really… self-paced guy. At this rate, you won't get liked by that girl no matter how hard you try to please her." Maou complained to Kuro for not spoiling to him.

AND KURO TOOK THAT PERSONALLY. "Wh-!? She'll not like me no matter how hard I try…!? :/" Kuro seemed like he was about to cry.

"You stupid. You don't say such a word to children like me." And… Kuro cried.

"Ahh… I forgot that you were but a child right now. Damn, act like a real one if you're a child tch." Maou clicked his tongue.

"A~nyway, I'm going to explain to you more about combat system while we're bored." Maou ignored Kuro's wailing.

"Let's start from physical…, or from the speed we're going, we may arrive at the empire the time I finish explaining the physical."

*sobs* *sobs*

"The most basic out of basic: some dumbass made a ranking about strength. Level 1: Basic -

Level 2: Expert - Level 3: Master - Level 4: Archmage / King - Level 5: Celestial - Level 6: Divine. I forgot how they measure these things up since I've long since surpassed these charts and there's no point in remembering it."

"The worst thing among it is they also goddamn made a rank about talents. Talk about making this world even boring: Level 1: Trash - Level 2: Common - Level 3: Exceptional - Level 4: Talented - Level 5: Genius - Level 6: Monster. Personally, I think potential is something that couldn't, and shouldn't be measured up by others. By doing this, they're limiting their own potential for temporary happiness. I fucking hate this."

Maou was especially angry about this, that his eyes turned slightly silveric and he was unconsciously emitting an pressures of death.
