The SSS Ranked Demon King Goes to the Hero Academy-Chapter 56: Mango Juice.

The demon king was drinking mango juice, calmly.

The dense, sweet liquid descended down his throat at a refreshing temperature. It was undoubtedly a pleasant and pleasurable sensation.

The waitress looked at Aku with pleasure. There was nothing better for a seller than seeing a satisfied customer.

Though at that moment she wasn’t earning anything.

"I see you were hungry. You’ve tried many things," the waitress commented with a smile.

Aku tilted his head with confusion.

Was it bad manners to eat too much or something like that?

He, who wasn’t aware of human customs, couldn’t help but question everything.

"Did I do something wrong?" the demon king asked coldly, observing the waitress with his dark eyes.

The girl hurried to shake her head energetically.

"No! It’s not that. I didn’t say it was bad. I mean, I’m sure participating in a trial like that made you very hungry," the woman responded with some nervousness and guilt.

She didn’t want to make Aku uncomfortable.

Aku tilted his head, somewhat confused.

Did fighting make you hungry?

Well, it was logical. After all, fighting required making an effort, an effort that had to be paid with energy.

Generally, the energy of living beings comes from food, so after exercising it was natural and very logical for a living being to be hungry.

However, Aku didn’t feel hungry as such, since he didn’t need to eat.

But he could smell and taste food, so he did it.

In itself, one could say Aku was eating solely for the pleasure of eating.

It was quite an experience for him.

"I understand," the boy responded calmly as he took another sip of his mango juice.

Then his eyes opened wide.

Not because the mango juice’s flavor had moved him. There was another reason behind his surprise.

He had felt it, how the essence of chaos had infiltrated inside the Argos’s barrier, somewhere in it.

"How strange," the demon king commented with a slight tone of surprise.

The waitress looked at him strangely, not understanding the boy’s reaction.

"Is something wrong?" the woman asked with curiosity.

However, the demon king wasn’t sure whether to respond, though at the same time he was starting to feel more filtrations of chaos essence entering the Argos.

"Looks like we have an unpleasant visit," Sylvie commented seriously as she sipped from a chocolate milkshake, making noise with her straw.

Aku looked at the fairy surprised.

She had noticed it too?

"So you could perceive it too," the demon king commented with a faint tone of surprise.

Sylvie shrugged, as if that feat wasn’t a big deal.

"Actually, I noticed how the barrier weakened just before, which is strange," Sylvie responded, taking another sip of her milkshake calmly, as if she wasn’t worried at all that the Argos was being besieged.

Aku brought his hand to his chin, stroking it as he reflected.

He hadn’t noticed the barrier had weakened. Did Sylvie have better senses than him?

However, there was something else that caught the demon king’s attention about what Sylvie had said.

The barrier had weakened?

What was the reason?

The demon king turned to observe the fairy more carefully.

"Do you think they’re putting us through some kind of trial?" Aku asked with curiosity.

The fairy didn’t even deign to turn to look at Aku. She simply took another sip of her chocolate milkshake.

"Could be," she responded. "Though it could also be that someone infiltrated and acted from within to finish off the heroes."

The fairy responded with utmost calm as she took a few last sips of her milkshake, emitting annoying sounds.

Aku raised an eyebrow upon hearing that response.

Could someone really sneak into a place like this?

It was a valid question. However, Aku remembered he himself was, so to speak, an impostor.

He was the demon king of his world, who had killed and parasitized the body of the hero Alexander.

Aku had pretended to be a hero and had participated in an admission trial for a hero academy.

He had even used cursed weapons and chaos powers in the trial, though in a very weakened form. His nature remained the same.

Perhaps the security of that kind of organization wasn’t so strict.

Though at the same time, Aku remembered Bīng Xuě.

That had been a powerful opponent, but above all, a user of arts and powers more worthy of a villain than a hero.

In other words, perhaps it was common to see heroes with powers that appeared to be malignant, and that’s why he had managed to infiltrate.

"Yes, that’s also possible," Aku responded with a serious expression. That possibility couldn’t be ruled out.

Meanwhile, the waitress looked at them with confusion, not understanding what they could be talking about.

Unable to bear her curiosity much longer, the woman proceeded to ask.

"What are you talking about? Is something happening?" the woman asked with curiosity and confusion, casting glances at the fairy and demon king.

Sylvie shrugged, not giving it too much importance.

"Don’t worry, nothing important," she commented with indifference.

Aku also didn’t seem too worried about the situation. After all, he didn’t perceive large sources of Azoth. Besides, the Argos was full of "veteran" heroes, so to speak.

"You’ll find out in a moment," he answered calmly.

The woman tilted her head, not quite understanding both their words.

They were discussing a matter that seemed serious. However, their attitude was relaxed and calm.

It was confusing.

"Really? I don’t know if that answer helped me much," she responded, almost like a complaint toward both their indifference.

However, Aku knew what he meant when he said she would know soon.

Almost as if he had predicted it, the space behind the waitress began to crack, as if it were poorly tempered glass about to shatter.

And as expected, it shattered, creating a fissure in space itself, a spatial crack which released a toxic and unpleasant essence as soon as it opened, like an ominous poison.

"Kyaaa!" the woman screamed, startled, jumping backward.

That had given her quite a scare.

Though Aku and Sylvie weren’t surprised at all, almost as if they had expected it.
