The silence in the room was absolute, broken only by the rhythmic scratching of a quill pen on antique paper. Arata Sparda sat on the edge of the bed, wearing the black and red uniform of the Biblia Academy. At 17, his reflection in the mirror was a living contradiction: the silver, unruly hair of his grandfather Dante, but the icy, analytical gaze of his uncle Vergil.
Just hours before, the sky had turned a sickly violet. Mundus, the King of the Underworld, had attempted to manifest through a dimensional rift. Arata had faced him alone, unleashing a lethal combination of Demon King Candidate magic and the raw power of Sparda blood. He won, but the effort sealed his magical core. Now, in an unknown place and with his powers fragmented, a strange black leather notebook vibrated on the table: the Journal of Destiny.
Arata began to write, pouring the venom of years onto the paper:
"Day 1 at Biblia Academy. Hatred keeps me going. Sirzechs Lucifer... 'father'... you abandoned me at age 4 after my mother's death. You looked at me as if my existence were a miscalculation. You didn't know that the blood of Sparda doesn't kneel; it rises to behead. I will use this academy and its Trinity Seven. I will make them my pieces. I don't seek justice, I seek Rebellion."
Arata didn't know it, but his "private diary" was an open net. Miles away, in the Kuoh Occult Club, Rias Gremory dropped her teacup when an identical diary appeared on her table. "A nephew? Sirzechs let a child die?" she thought in horror as Arata's words materialized before her eyes. At the Lucifer mansion, Grayfia also closed the book with trembling hands, recognizing the handwriting of the woman Sirzechs had betrayed.
The Encounter and the Professor's Office
Arata left his room with a lopsided smile, adjusting his jacket as if he were going to a party, not a war. He was intercepted by a woman of austere beauty: Lilith Asami.
"Well, well... does the welcoming committee include an S-class beauty, or has my luck finally changed?" Arata quipped with classic Dante-esque swagger. "Tell me, darling, are you here to escort me or ask for an autograph?"
Lilith, who had her own copy of the diary tucked into her skirt, looked at him with a mixture of pity and indignation. "Stop joking around, Sparda. I'm Professor Asami. Follow me to my office to formalize your admission."
"Professor? Oh, this is getting interesting. I love private lessons," Arata winked.
Back in the office, Lilith tried to assert her authority, but Arata leaned on her desk, invading her space, and wrote a new entry in front of her, staring intently:
"My new 'teacher' thinks she can tame a wolf. Lilith is beautiful when she tries to be authoritarian, but I'm going to break her hierarchy. The Archive of Lust... will soon understand that you can't play with fire without getting burned by the flames of Hell."
Under the desk, Lilith's diary vibrated. She read her thoughts in real time, feeling her face burn. The boy was shameless, but the diary also showed her glimpses of the trauma he hid behind his jester's mask.
The Entrance Exam: Steel Against Wind
The tension was broken by Director Biblia. Arata was ushered into the main office, a reinforced space where Levi Kazama, the ninja of the Trinity Seven, awaited him.
"Touch Levi once or survive three minutes," the Director declared.
Levi vanished in the blink of an eye. Wind attacks and kunai whizzed through the room. Arata, his powers sealed, didn't use magic. He used style. He dodged a slash with a backflip, sneering, "Is that all? My grandma could attack faster with a wooden spoon!"
With Trickster moves and precise Royal Guard blocks, he dispelled the impacts with the palm of his hand. In a burst of pure speed, he appeared behind the ninja and touched her shoulder. "Checkmate, ninja. Next time, try being more... agile."
Levi stepped back, sheathing his katana with a respectful smile. "You're amusing, Sparda-kun."
Sora's Awakening: The Final Piece
The Director, satisfied, produced a box containing seals from the Underworld. "This belonged to your lineage, Arata. The soul of a forbidden magic system."
Upon touching the box, the seals burst into crimson flames. A light took human form: a silver-haired girl with a mischievous look.
"Finally, a breath of fresh air! I am Sora, the Manuscript of Astil," she said, hovering around Arata. "So you are my new Master. You have the eyes of old Dante, but you smell far more dangerous. My powers are yours... and so are my teasing. By the way, Master... does your teacher know you were checking out her cleavage five minutes ago?"
Arata choked on his own saliva as Lilith, standing in the doorway, turned bright red. The Headmaster merely sighed.
Arata smiled, feeling Sora bond with his soul. He picked up his diary and wrote the last entry of the day:
"The Headmaster has given me a Queen for my chessboard. Sora is as cheeky as I am, I love it. Sirzechs, Rias... feel the ground tremble. The countdown for the Gremorys has begun. And Lilith... prepare yourself, because your best student is ready to teach you a lesson."
At Kuoh Academy: Rias closed her diary with determination: "Akeno, prepare the teleportation circle. Tomorrow I'm going to Biblia Academy. I have to look that boy in the eye before he burns the whole world down."
