Cycle Zero : reincarnated as the Demon King, Now What?

Arrival in velmoor

Diablo called Rias and said to her, “I will be leaving Malgorath for Velmoor. I want you to oversee everything that happens here.” Then he left.

He got there using instant teleportation. He entered, and the sky looked clear. He walked for a moment, then saw a little girl being bullied by a blacksmith.

“You should do what you’re told, you piece of shit,” he said, whipping her with a whip.

Diablo held his hand and said, “Don’t you dare hit her. What has she done?”

The blacksmith said, “How is that any of your concern?”

Diablo thought for a while, then left. “Oh well, this is not the reason why I am here,” he said to himself.

He went to an adventurer’s guild and said he would like to register. He was taken to a special room to test his abilities.

“Sir, please touch the orb,” the receptionist said. “We would like to check how much MP you possess.”

When he touched it, the orb broke, and she said, “Something like this has never happened before.” She went to call the guild master, and he rushed down to confirm what he was told.

Then he asked, “What is your name, sir?”

“My name is Diablo,” he said.

The guild master said, “My name is Vasryn Kael’dathor, and this is my assistant, Isyrae Thornveil. Let’s proceed to your second test: how many elemental magics can you use?”

He touched the orb, and it revealed all his elemental magic.

Core elements:

• Fire

• Water

• Wind/Air

• Earth

• Lightning/Thunder

• Ice

“What?” Isyrae said in shock. “Nobody has been capable of doing this.”

After the test evaluation, he was set to be an E-rank adventurer despite his capabilities. He accepted and left to find somewhere to stay, since he would be in Velmoor for a long time. He went to a nearby tavern and asked to book a room for himself.

“I have enough money to buy an entire base, but I’d like to stay low-key for now,” he said to himself. He smiled, then went to bed.

The next morning, he went to the guild to take on some quests. When he got there, almost all the quests had already been taken. The only one left was to gather herbs from a nearby forest of Velmoor. He accepted, then left.

Walking down the hills, he saw a group of adventurers being attacked by a group of goblins.

Goblins are weak, right? So why are they finding it hard to defeat them? I remember from the game I created that goblins are low-ranked monsters, within the rank of F to D. He checked the stats of the adventurers with his unique skill, Status View, and saw they were D rank, with one E rank among them. There were four in total, making up a party. I think I will wait and see if they need help before I step in.

He watched how the warrior class fought and thought he had a lot to learn.

The warrior, a broad-shouldered man with a battered iron shield, led the front line, taking the brunt of the goblins’ crude attacks and driving them back with heavy, disciplined strikes. Beside him, a mage in the group hurled small bursts of fire at the goblins circling the edges, keeping them from flanking the party. The E-rank member, clearly the least experienced, stayed close to the back, firing arrows whenever an opening appeared, though her aim wavered under the pressure.

The goblins, roughly eight of them, fought with crude spears and jagged daggers, snarling and darting in short bursts. They were fast but disorganized, relying on numbers rather than skill. The warrior anchored the group’s formation, shouting directions, while the mage’s fire spells picked off the weaker goblins one by one. Slowly, through coordination and grinding effort, the party thinned the goblins’ numbers, cutting them down two and three at a time until only a handful remained. The fighting was messy and exhausting, full of near misses and scrambled footing, but their teamwork held.

Finally, the last of the visible goblins fell, and the adventurers lowered their weapons, breathing hard.

They did it after all, Diablo thought.

The adventurers, exhausted after defeating the goblins, dropped their guard, unaware that a goblin shaman had been hanging back in the treeline the entire fight, chanting under its breath. It raised a crooked staff and unleashed a bolt of dark energy toward the warrior, who had just sheathed his sword.

“Watch out!” Diablo shouted, but the distance and the party’s own noise drowned him out. The warrior turned too late. The bolt struck him square in the chest, throwing him to the ground, badly injured. The shaman advanced, staff raised for a killing blow.

Diablo moved fast as light, closing the distance in an instant. He summoned his sword from his pocket dimension mid-stride and drove it through the goblin shaman before it could finish its spell, killing it in a single strike.

The rest of the party stared at him, stunned. “Isn’t he the new guy? How is he that strong?” one of them murmured. Diablo said nothing. He turned and walked away, leaving them before they could ask him anything.

Night came quickly.

Wait, I forgot to pick up the herbs! He hurried back into the forest to search for them, gathering as much as he had been asked to collect. It took him about forty minutes.

He went back to the guild to report and submit the herbs.

“This is your pay,” Isyrae said.

He was about to leave when he felt someone touch his shoulder.

“Thank you for what you did back there. You saved us. My name is Natsu, and these are my guild members,” he said. “This is Mari, Akeno, and Leo.”

He introduced his guild and invited Diablo to sit with them for a drink. After the long encounter, Diablo went to the tavern.
