The Arrival of the Hero and the Demon King

A young man with silver hair and deep sea blue eyes looked around himself. "What? For a world with advanced technology, they still use bullets."

"Shit! My magic senses is getting jammed. It looks like i need to find him manually."

Meanwhile, a young man with whit hair and ruby eyes was running along the shore of a beach. "Brother! Where are you?"

"Magic sense is no use. I can't find him like this." He looked around and saw people staring at him. "I guess, I need to blend in first, and also obtain information first, like brother says."

• Sterling Residence/Bakery, Aeon Street, Orario •

A young man with silver hair and deep sea blue eyes is currently massaging a dough. He's wearing a body-fitted black long sleeve shirt underneath th pink apron that hid his very rare 8-pack abs that you rarely see. And yes, a pink apron covered the sight.

This is Silver Sterling, the one who owns this house which is also a bakery known for high quality breads. But, of course, the ingredients provided by the Demeter Familia, an Agriculture familia, as they have the best harvest of wheat and other ingredients for his bakery's success.

But what people didn't know was that he is the famous Demon King who was defeated 2 years ago. But defeated? No, he wasn't really defeated at all. He wa the one who planned this whole peace thingy.

His plan was simple: He will disguised himself as a very cruel king who ravages the land and shall conquer all other kingdoms and countries in order to force the whole world to unite and defeat him, while his allies; his friends Arthur Róich, Leonidas Terezis, Lucius Augustus, his adopted brother Bell Cranel, the gods Zeus, Hera, Loki, Freya, Artemis, Aphrodite, Odin, Thor, and Uranus will try to figure out his next move to defeat him in a battle of wits while he bears the weight of sin, killing countless humans, elves, dwarves, prums, and other more races. He beared all the hate of all races to unite all countries, cities, kingdoms. With the help of Hades, his Familia God, and his participation in battle himself, he managed to become strong, so strong that it pushed all who participated and survived in the war to become stronger. At a young age of 3, he became a member of Hera Familia, converted into Hephaestus Familia at Level 3, reached level 8 in just 14 years, converted to Hades Familia a year after witnessing how people can never attain peace without war and started this plan. Fought against the 13 'Warriors of Light' for 3 years until he was successfully 'defeated' by beng able to destroy the kingdom he built along with the evil army he assembled who can never be saved from darkness. And in these 2 years, Silver had long been baking delicious bread and other delicacies such as cakes, pies, waffles, and other more as long as it is using oven to make.

On the second floor of the bakery, there stood a young man with red eyes and white hair. He have 6-pack abs, not as impressive as his brother's, but that is because they are not real brothers, but cousins instead, hence the difference in physical appearances and last names for some reason.

This is Bell Cranel, and his adoptive brother is obviously Silver Sterling. 19 years old, 6 feet tall, and lean body build, unlike his brother's which is 22-year old, 7-foot 1-inch tall, and have bigger build than him.

Bell didn't want to abandon his family name due to growing up with this name and he came to love it. Silver respected that, and there's no really a law that will change your family name as this world has no need for birth certificate for clarification or adoption papers to adopt a person as in this kind of era, it was either forced slavery, or the person decided to live with other people.

Aside from his grandfather who turned out to be Zeus, the god of the once famous familia in Orario, Silver is the only person connected to him by blood. It's not really unexpected that he would go with his cousin whom he called brother now.

He is also one of the warriors chosen to defeat his brother, the so-called Demon King who brought terror to the whole world, to his own birthplace, to his own cherished city of Orario, just to bring peace that cannot be attained just by conquering nor communicating with each other. He knows that people would understand each other more if they all faced an enemy that threatens all of them, and in order to defeat this threat, they're forced to trust each other and combine their efforts together.

He remembered the time when he was a member of the 13 Warriors of Light, otherwise known as Knights of the Round Table between its members. The leader is Arthur Róich, or Arthur Pendragon as his real name, is a very powerful knight who have both a powerful defensive sheath called Avalon, and a powerful Holy Sword Excalibur which were forged by his brother. Actually, all weapons of the 13 Knights are crafted by him: Excalibur (Fate), Durandal (Tales of Innocence), Cerberus (Gungrave), Ruyi Jingu Bang (Fate), Murasame (AGK), Lostvayne (7 Deadly Sins), Balmung (FFXV), Polar Star (Genshin Impact), Thundering Pulse (Genshin Impact), Gaia Cleaver (Tales of Vesperia), Virtuous Contract(NieR: Automata), Rebellion (DMC), and his weapons, Kanshō and Bakuya (Fate).

Bell stood up and quickly took a bath. He got down and took a seat after taking a bath, and a plate was placed in front of him in no time. So does his older brother who also took a seat to eat as well.

Bell decided to ask his brother about one thing that made him interested.

"Brother, I've noticed that you've been staying up more late at night. I've also seen all your notes in your room when I tried to find d you the other day, but I don't understand whatever it says."

Silver replied, "About that... I've noticed a disturbance, not only me, but the others as well. The four of us decided to take a look. What we discovered is something very strange. It was a Dimensional Crack, not something anyone could do, and Lucius, or Nero as he prefer, decided to take a closer look. Then, he discovered something..."

Bell fell silent and just waited for the next sentences to be uttered.

"It was naturally made dimensional crack. Whatever natural entity who made such a crack, it made the monster's and the Dungeon to become more aggressive. We're trying to find a way to seal it, and we did."

Bell knew it, thus. "But?"

"But, it must be sealed on the other side. Then, we'll need to find a way to make an artificial crack at which the Natural Will of the World will repair. Natural phenomenon cannot be repaired by Natural Means, thus we mortals existed to do such. Do our best to repair nature. Do you understand?"

Bell nodded, "Yes. That means, the natural dimensional crack is either made by the will of the world or it was caused by another natural will, and since it is natural, it cannot be repaired by the will since the will of the world only acts against unnatural phenomenon such as creating a portal to another place, and thus the portal can only be maintained to be open if they are supllied enough Mana to defy the will to close it."

"That's right. You've become more smarter. I seem to remember that all your answers before were to head in there and do all what you can do."

Bell blushed and just hid it away from his brother who is chuckling at the fluster young man.

• 13 days later •

"Are you sure you're going to do this, Silver? You know we'll that your brother can't really managed the bakery that well." A young man in his early 20s with blond hair and green eyes spoke in worry even with his stoic face.

"Don't worry about me, Arthur. Or should I say, King Arthur?" Silver spoke with a deadpan face.

Arthur didn't speak. The comment was to remind him that he cannot disappear for too long, so he cannot be the one to do the mission to seal the crack in the other side. Beside Arthur, there is a redhead wearing red clothes with gold ascents who placed a hand on Arthur's shoulder and spoke.

"He's right, Arthur. We are kings of our kingdom, my Amor, and your Cametol. Leo's kingdom is Sparte. Our kingdom needed us, our people needed us to make sure they don't go down on a path that will spark war again."

The black haired and red eyed young man nodded, "You know that we'll."

Arthur gave up with a sigh. "Fine... But-" he turned to look at Silver. "You better come back, or we'll open the crack just to find you."

The other two also nodded in agreement.

The stoic and stone face of Silver softened and smiled a little. "You guys are troublesome bunch. I'm not, so I'll be coming back."

As Silver was about to enter through the spatial crack, someone called him.

"Brother! I'm coming with you!"

"N-"

"I won't take a no!"

"Urgh... *sigh*... Fine."

The Moon Rabbit, Bell Cranel, and the Silver Wolf, Silver Sterling walked through the portal after they bid their farewell to the other who also came with Bell.

After they got out of the portal, Silver quickly sealed the spatial crack. With the use of magic and some runes, he closed it tightly, thus no way to open it without any knowledge about closing it.

Silver looked around and saw Bell is fighting some monsters. He also saw some kind of technology lying about. So, when he checked them out, he found out that they are in the Gapra Whitewood. He quickly searched for a map and searched for the quickest way to get out. He also found a map of what seemed to be this world's planetoid name. It was called Cocoon.

"The name felt like it's literally gonna be a cocoon that will be discarded once the greater evolution come out." He muttered to himself.

"Is that a map? Gapra Whitewood? This place is filled with experimentend animal..." Bell uttered the last sentence in disgust and hate.

"Right. Follow me, we'll be out in no time." Silver's tone also carried the same emotion, but his face is still stoic.

A huge door opened, Silver and Bell emerged. The day was nice until-

*BOOM!*

They were almost killed by what seem to be an RPG. Luckily, they managed to jump away. As they are level 10 and level 8 respectively, they can jump more than 500 meters high, so it's easy for them to escape such weapon.

One of the soldiers reported in his communication unit in his ear, or known as Comm Unit. "Infiltrators found, sir! We've already sent a warning shot. What should we do to them, sir?"

"Capture them."

With Silver's sharpened senses, he naturally heard that, thus he told his brother. "Bell, we'll split here to divide both their attention and firepower. Once you got out, find a city called Bodhum, we'll stay there in the meantime."

Bell turned to look at his brother and asked, "Is that near?"

Silver replied, "Not exactly, but that will our meeting point. It's an island. It's easy to find. We have to divert their attention-"

"NOW!"

The both of them ran out of their hiding and dodged a lot of bullets until it was stopped.

"Idiots! We have to capture them, use your melee weapons to knock them out. Although they wear armor, I doubt such barbaric armor could stop our bullets."

Meanwhile, Silver only snorted at such idiocy. Well, it's not his problem if these people don't know how to forge armor that cannot be scratched by any adventurer below level 8 with an enchantment on their sword to become 10× sharper, making them cut through any thick metal, but still won't cut his armors.

"Don't let them escape! Use your melee weapon to catch them! Bring some Pantherons to quickly find them!"
