Prologue

Once upon a time, there was a mystical world formed with twenty-one different lands. In each land, different types of creatures were inhabiting and create their kingdoms: Fairies, elves, paladins, nymphs, trolls, angels, dark angels, seraphs, harpies, warriors, and of course humans. This world was called Avillerius. Among the lands, there was a prestigious and famous city where warriors and royal blood lived that sometimes named the dangerous and mightiest type of people named Avilluz, the central of Avillerius.

Arca was the ancient fairy queen and the wisest one ruling in the city, along with the strongest and skillful seraphim swordsman, King Bardou. They're not just rulers, but they also the protector of the sacred fifteen gems of Lanzar that were at the secret haven of the palace. The two ancient angelus Gratia and Losuie created these powerful gems. Each one of them has a hidden symbol that holds every power of Avillerius and is protected by generation. But what's more significant than these? It was a Navillerian Crystal that controls every power of Avillerius as well as the sacred gems. This one wasn't just a typical crystal, but it's a living crystal under the image of the blue butterfly that holds the alpha power. According to the prophecy, the Navillerian Crystal was in touch with one of the destined warriors who has the blood of angelus and gifted with two pairs of wings shining in bluish-white light. This particular person they talked about was the dual wielder sword girl with an assassin skill of fighting, and the name of the said destined warrior was Black Navillerian Angelus. She got the sapphire blue eyes sparkling like stars. Her hair faded from black to azure down to her thighs, shining like her eyes. At first, she was meek and gentle, but when someone attempted to hurt an innocent or even her loved ones, she doesn't hesitate to draw her swords and slash an enemy into pieces using her unique sword skill called "The Butterfly's Kiss."

Aside from Black Navillerian Angelus, two mighty warriors accompanied her for the mission. The first one was the Night Black Phaser: a skillful dual-wielding angelus who uses a rare silver light fire that's also flaming inside his heart as well as his eyes and wings. He even has a silver highlight on the left side of his jet-black hair depicting his power from the silver butterfly of Gratia. As he holds his swords in the battle, in just a blink of an eye, he released the sempiternal slashes as the rare flaming light appears like an aurora borealis on each blade. He called the sword skill "Blade Dance of the Night." The other one was an angelus and a single sword wielder with a silver-white highlight on the right side of his scarlet hair; even his eyes and wings were in the same color. What's remarkable in his sword skill was every time he swings his sword and strikes an enemy, life force drains on the blade and gives him healing from his wounds. The eyes also depict his power from the scarlet butterfly of Losuie given to him like Night Black Phaser. His name was Scarlet-eyed Archangel. Until now, no one knows what the name of his secret sword skill is.

The three of them have a mission to protect Avillerius from Arca's wicked twin sister Avicta: the queen of Darkorous. She's eager to steal the fifteen gems to gain all the powers of Avillerius as she breaks the secret codes hiding on them and also to stole Arca's throne. She invaded Avilluz along with her terbeauses: the dark forces to get the said gems. They weren't afraid to risk their lives for the sake of prominent and significant lands' safety and protection against her. During the battle, Black Navillerian Angelus faced Avicta as she protects the Avillerius from her greedy and vile intentions. She doesn't want any single drop of blood to gushes on the ground crying for justice. With all her might, she's not afraid to cross his swords from her as they exchange each attack. Night Black Phaser and Scarlet-eyed Archangel were taking over to protect the innocents stuck in the city and crying for help. They slew the four general terbaeuses as they kept their duty to protect them. Avicta was getting furious with Black Navillerian Angelus and eager to steal their gems and powers as she used her ability called "Circrase Stike," where the dark energy encircles her blade and erase a victim. Black Navillerian Angelus was almost by her attacks and was helped by Gratia and Losuie to activate her alpha powers together with her comrades. With the power of the three protectors of Avillerius, they successfully defeated Avicta; before she lost her breath, she left vengeful words that she'll return to steal the gems and rid those who oppose her, even the three warriors of Avillerius and her twin sister.
