Against Greek Pantheon

Theo, now that he's ready with his peerage, can head towards Mount Olympus. Then, Theo settles in Greece. Afterward, Theo searches for the dimension where Mount Olympus exists, and it seems to be heavily guarded against unauthorized entries. But it's not very important to Theo, even though Zeus may not be at the helm of Olympus, he can be said to be the most authoritative figure there (current leader Apollo).

Theo settles in there with his peerage, and it doesn't take long for the gods to sense it, triggering an alarm situation.

Theo is now standing in front of Mount Olympus, looking up, and observing it. Mount Olympus appears larger than Everest. Without wasting time, Theo immediately appears with his peerage at the gathering place of the gods, surprising all the Olympian gods. All twelve Olympians are there (Poseidon and Hades resembling their record of ragnarok forms and zeus is in god of war 3 verison).

Everyone is surprised because they hadn't thought devils could attempt such a thing.

Theo raises his hand and smiles, "Hello, Olympians, I'm here to negotiate."

Then all the shadow soldiers under Theo's command emerge, creating a terrifying scene with an army consisting of all races. Apollo is angry, Hades is likely plotting, and Ares is waiting for orders, albeit somewhat foolishly.

As Apollo is about to speak, Zeus stops him, now in a very serious mode. Zeus says, "Speak, demon, what do you want and what do you offer?"

Theo replies, "What I want can only be provided by Hades. I want 10,000 human souls. If you provide me with them, I will give you something in return: a longer lifespan. After all, you don't want to be killed now, do you?"

Theo is now challenging all of Olympus. Artemis has already prepared her bow.

Hades intervenes because the request concerns him. Hades says, "I am the lord of the dead. Do you think you can kill me, bat?"

Theo smiles at this and says nothing.

Upon this, Poseidon makes the first move. He swiftly advances towards Theo and thrusts his trident, but it's halted by Theo's Limitless. Without waiting, Theo delivers a kick to Poseidon's abdomen, Poseidon flies by Theo's kicks, and Zeus comes after him with lightning in his hand. The sky darkens, and just as the lightning is about to strike Theo directly, he swallows it with Gluttony. Meanwhile, Hades, observing the warring armies, is surprised as all creature beings turn into shadows and attack the others. Hades then turns his attention and creates a magical ball embodying the power of death, heading straight for Theo at full speed. Sensing the danger, Theo instinctively raises a finger, unleashing a small demonic force that amplifies the spell into flames.

Jio Graze

As the spell advances at full speed, Theo's spell collides with Hades' spell, causing to hades spell to vanish as if it had never existed.

Jio Graze narrowly avoids hitting Hades and instead crashes into the mountain behind him, causing it to explode. Seeing this, the Olympian gods freeze, realizing that if Theo's finger produced such power.

What would happen if he cast the spell with his hand?

The Olympians understood what they were facing, but their pride wouldn't allow them to give up.

Akeno was countering Apollo's light with her lightning, occasionally engaging in close combat with Hermes and Athena.

Tiamat was easily defeating Ares, treating him like a piece of trash, lifting him by the ankle, and slamming him to the ground now and then.

Valerie was effortlessly deflecting Artemis's arrows, and since Demeter was attacking from afar with plants, Valerie was killing the plants and using them against Demeter.

In close combat technique, Valerie was second only to Theo in the peerage.

(Tiamat was not skilled in technique but in brute force, compared to Valerie.)

Zeus, no matter how much he attacked Theo with all his lightning, was useless.

Poseidon was throwing his trident so fast that afterimages were forming, yet they were all deflected by Theo.

Hades, on the other hand, was trying to assist his brothers from the sidelines with some spells.

Theo was happy to see this because it was the first time he had entered such an exciting battle. Then, just as Poseidon was about to thrust his trident again, Theo grabbed it. Poseidon was surprised to see this. Without further ado, Theo delivered a swift kick to Poseidon's jaw with his other hand, sending Poseidon flying into the air. As Poseidon ascended, Theo grabbed him by the ankle and imitated Tiamat, slamming Poseidon from the ground. Theo felt satisfied.

Then Theo turned around and said, "2 out of 3," clearly trying to provoke him. Meanwhile, Tiamat had already defeated Ares and was helping Akeno, while Valerie was managing things. Hades had now brought out a scythe and swung it towards Theo. There was a scent of death emanating from the scythe.

Theo effortlessly dodged it.

At that moment, Zeus on the edge is now desperate, and the move he used to defeat his father comes to mind.

It's now the last move he can make to defeat this kid, and it's time to use it.

Zeus raises his fist, and it seems as if time has stopped, including Theo; Zeus's fist transcends time and space. He swings his fist toward Theo, but what he doesn't expect is Theo to use a move he learned earlier: Divine Reflection. This move has embedded into Theo's muscles, a power not to be underestimated.

While Zeus doesn't expect it, Theo punches him in the face with the same move. Zeus goes flying into the air.

Then time resumes its flow. Theo: "That was a nice move, old man, but now it's my turn."

Hades, in the corner, hadn't understood what happened. Then Theo immediately appears in front of Hades, who is standing, and Hades falls backward as Theo approaches.

Meanwhile, Valerie, Tiamat, and Akeno have already defeated all the remaining Olympians. From Theo's shadow army of 5000 soldiers, are become 20000 soldiers.

Theo then brings down his fist on Hades. It feels as if Atlas has hit Hades. Theo doesn't stop, punching Hades until Theo's face is covered in his blood. Then he turns to Valerie.

Theo: "Heal him, Valerie."

Valerie obeys without question, listening to Theo's command. Theo continues to relentlessly beat Hades' face with his fists and then heals him again. This repeats ten times. Hades' spirit is shattered, all Olympians are healed, and they witness Theo's brutality in awe and fear.

Theo decides to speak to Hades: "If you had listened to me from the beginning, it wouldn't have come to this. But you let your pride get in the way, so you faced your punishment. Now, Hades, I know Lilith is in your hands. I hope you'll cooperate and give her to me. Otherwise, you'll perish, and I've shown even Death Lords can die, haven't I?"

Hades crazily shakes his head. "Oh, by the way, I need 10,000 human souls. If you don't give them, you'll be dead. Got it?"

Hades doesn't care anymore. Even if Theo wants the underworld, he'll give it to him on a gold plate.

Theo smiles upon hearing this: "I wish it had been this easy from the start."

Then Theo stands up and, using his time magic, restores Olympus as if it hadn't been destroyed, healing all the worn-out gods, including Zeus and Poseidon.

No one can speak; they're all traumatized by Theo's actions. Even Aphrodite and Hestia, watching from the sidelines, are shocked.

Theo helps Hades up, puts his hand on his shoulder, and smiles.

Theo: "I wish you were always like this, Hades-chan."

Then, without much talk, Hades takes him to Tartarus and agrees to the deal (under threat), handing over 10,000 human souls, all sinners.

Theo returns to his peerage with a serious face.

Theo: "Wait for me and protect me for two days. Let no one come near."

Theo performs a ritual.

Meanwhile, in Heaven...

Michael, as usual, manages God's system, overseeing people's prayers and controlling them. But suddenly, Heaven shakes, and the system goes into crisis mode.

Unauthorized access is written on the system.

In Tartarus...

Theo begins the ritual, accessing Heaven's system without permission, making himself the most authorized. Then he unlocks the restrictions for his evolution.

Using the souls, he begins his evolution. At that moment, all supernatural forces in the world start to hear the world's voice.

Evolution request for Theo Gremory accepted.

Required souls are obtained.

The devil race evolves into the Devil King.

Theo's appearance begins to change; his hair grows, his height reaches 190cm, and his eyes start changing with the evolution. His whole body evolves over two days.

Finally, the evolution is complete. Theo's once-innocent face turns handsome. He now resembles a top model.

Meanwhile, all supernatural beings in the world are going crazy upon hearing these voices.

When Theo's evolution finishes, he takes Lilith with him; he is almost a lump of flesh. When they return home, theo will heal her.

And thus, Theo achieves his goal.
