In a very dark place, Milus is quietly watching the battlefield at the dungeon.
Milus noticed something and said, "wait, isn't that Thor? What is he doing here? From the way, he watches everything he was just observing the battlefield. I think I should try to see how everyone will die here."
Milus used a skill and said, "death seeker eye!"
Milus slowly observes everyone's death until it's Rosario's turn.
As Milus stared at Rosario, she encountered an unexplainable pain in her whole body. She screams as the pain that she's experiencing increases to do point that her blood vessels are exploding.
Milus said, "ahhhh, stop it! Stoooop! I can't take this anymore!"
Everything returns to normal and Milus body starts to recover she took glances at Rosario and said, "this woman has a lot of death awaiting her. Now I'm starting to feel like I want to stay by her side and see how things will end."
The golden egg started to change its color. The surrounding of the golden egg starts to become chaotic as the golden egg turned into a demonic egg.
The voice of the world echoed and said, "proficiency has been met, Rosario Mourning Star is ready to evolve."
An earthquake as Rosario is about to awaken as a demon. Moreover, the egg is shaking like something is forcing it to open but it failed.
A few minutes later…
After countless attempts the voice of the world speak up and said, "evolution failed, executing force evolution."
A powerful shoot towards the egg and destroy it completely and as the eggshell was destroyed Milus slowly changes and turns into heaven and sea.
Milus was mesmerized by the sudden change and she said, "wow, it's so beautiful here. Rosario's spiritual heart changed into this. It's so beautiful."
As the eggs shells falls huge black and red wings sprung out of the egg and the eggshells were fully destroyed.
A teenage form of Rosario appeared with horns and a much more mature body and insignia on her forehead.
The eggshells melted and turned into a black robe that she wears.
The voice of the world said, "Rosario Mourning Star has been successfully awakened as a demon. Now, attempting skills, weapons, equipment, and wings evolution."
A few moments later:
The voice of the world speak up and said, "skill evolution has been successfully executed. Skill: devour evolved into gluttony, space manipulation evolved into space dominion, Arcadian wings evolved into dark knight wings Arcadian staff and grimoire evolved into Kamui staff and grimoire, Arcadian robe evolved underworld kings robe, and shadow manipulation evolved into ultimate skill shadow king Melchizedek. Attempting natural skills evolution."
Milus was shocked and said, "what the fuck? She has 2 sin series skills, how did that happen?! How the hell she managed to obtain those 2? Not just that. They are the strongest among the 7 sin series skills. Now, her natural skill is going to evolve I wonder what would turn into?"
A ball of light appeared up in the sky and a pair of shiny wings sprung out of it and it slowly falls right in front of Milus. The ball took a form of an angel with a golden and shiny robe. All of her skin is color gold and white including her hair.
The voice of the world said, "the Natural skills have successfully evolved. Under this evolution the 2 skill has been successfully evolved, Great sage skill evolved into wisdom skill, and the book of knowledge evolved into ultimate skill king of knowledge Zeus. Attempting stats upgrades.."
Milus said to herself, "what the heck, her soul possesses 2 skills… wait, what's with the book of knowledge skill? I've never heard of that skill"
Milus looked at the angel and asked, "wait, why do you look like Rosario Mourning Star."
The angel said in a computerized voice "that is because I'm her natural or should I say a soul skill which is the great sage skill. I've been sleeping now it's my turn to make my move."
The voice of the world speak up and said, "stats have been successfully upgraded.

Athena said, "finally, the evolution process is over. Now that I'm awake ill make my move to end this chaos once and for all."
Milus asked, "how are you going to do that? We're stuck in here? You can't interfere with the issues outside?"
Athena said, "You're underestimating my capabilities Milus. I'll show you how powerful I can get."
While the evolution is an ongoing process Janna and Rory were able to defeat all of their opponents except Vermillion.
Janna asked, "let me help you, Rory. There is no need to push yourself this far."
Rory said, "now is not the time for holding me back, Janna. You go protect while I'll deal with him. I'm going all out and make sure he does right here and now!"
Janna said, "make sure you win this!"
Rory said, "you can count on me!"
Vermillion asked, "how are you going to kill me if I have the power of the 5 spirit kings there is no way you will match up my strength!"
The evolution process has ended and Janna shouted, "Rory, master's evolution is successful. Just hold on longer our master is going to wake up soon."
Rory shouted, "sure thing, I'll keep this weakling occupied!"
Vermillion said, "wow you're so confident. You're weak and yet you think highly of yourself. Your master managed to awaken into a pandonium demon but she's still weak just like you."
Rory said, "let's see if you can still say the same thing when I use my ultimate skill."
Vermillion smirked and said, "wow, so you have another ace in the hole. Let's see if it's going to save you."
Rory used a skill and said, "ultimate skill, hell execution!"
As Rory activates her skill the whole surrounding starts to turn into chaos like they are teleported into hell. She slowly turned into a very powerful demon that has sharp claws and scaly skin and a slender body. Her legs turned like beast legs and her eyes turned into color blood.
She screams like she has lost her sanity as her forehead burns in pain an insignia was imprinted on her forehead and 2 scaly and pointy tails sprung out of her body.
As she finish transforming she gave a deadly glare at Vermillion.
Vermillion said to himself, "I don't know why I feel like I'm about to die here but there is no way she can win against me, after all. It's only natural for a demon to lose against me since has no way of defeating spirits and I've perfectly replicated the power of the spirit kings. There is no way I'm going to lose to her."
Vermillion was surprised when Rory suddenly disappeared in front of him.
Vermillion looked around and said, "how the hell did she disappear in a blink of an eye?" Suddenly he felt a murderous aura closing in on his back.
He immediately jumps away to avoid it but it was too late.
Rory's hands move so fast to the point that no one can see them.
She sliced the whole dungeon into 2 along with Vermillion's legs.
Rory said in a demonic voice "I'll finish you off once and for all."
Vermillion said to himself, "this is bad, I never expected her to be this fast and powerful. I'll have to use the spirit king of lightning to much up with her overwhelming speed."
Vermillion used a skill and said, "ultimate skill, spirit king's transformation! Lightning spirit king Elestra!"
Rory clap slowly and laugh in a demonic voice and she said, "you know even if you use the spirit king's powers you still have no chance of winning against me."
Vermillion's legs regenerate and he stands up and he said, "hah, you're too confident for someone that is about to lose."
Rory said, "sigh, I guess I have to demonstrate my true power. Wait, I haven't used my skills yet after transforming into a demon. I wonder if you can handle it."
Vermillion used a skill and said, "lightning speed!"
After activating his skill he runs so fast around Rory like a race car and charges toward Rory.
Rory said, "sigh, pathetic."
Rory used a skill and said, "crimson dance!"
As Rory activates her skill time slowly stops.
Vermillion was surprised and said, "wow, so you can stop the time but I hope you know that in a frozen world you can't use magic and demons are only superior at using magic. Let's see how are you going to fight me!"
Vermillion tried to move but he can't move at all and he just remains in his attacking pose.
Vermillion asked, "wait, what is going on? Why I can't move in a frozen time?!"
Rory walk closer and said, "who's a weakling one now? You can't even move a finger and yet you're so arrogant."
Vermillion asked, "wait, are you a pandonium demon too?!"
Rory said, "you talk too much. I think it would be best for you to shut up and die."
Vermillion was being slashed to pieces and suddenly a huge can be heard and Yumi, Zestiya, and Esmeralda fly out of the explosion.
Zestiya shouted, "how dare you kill my subordinate?! Do you know what happens to people who kill my people? They die a horrible and so as you and your master."
Rory said, "he's so annoying so I silence him. My master has already forgiven him for getting in her way and didn't kill and yet he's not grateful at all and he insulted her. What happened to him is none of your business, he deserves it."
Zestiya got angry and attack her without showing any mercy.
Rory attacked her as well and they both move so fast as they exchange slashes against each other.
Zestiya used a skill and said, "pinnacle slash!"
Rory said to herself, "with that kind of attack ill die but if I counter it with my strongest attack I might survive."
Rory used a skill and said, "supernova slash!"
Her sword's aura radiates like it's about to blow up and she gives it a powerful slash.
Rory and Zestiya's swords attack and destroy the whole labyrinth.
The next chapter is ongoing.
