"...There she is!" Pterosaur air assault, the final battle against Tiamat!
About
"My children, they stepped over me to move forward—."
Characters
Bronze eyes, black hair, wearing a black Mystic Code. The last Master of humanity, possessing an ordinary but indomitable spirit. While lacking direct combat power, he commands through deep bonds with Servants, and his three Command Spells capable of leading to limit breaks are his greatest weapon.
Violet eyes, short light-pink hair, wearing black armor. A devoted Shielder who would lay down her life for her Master. The core of absolute defense, using her massive cross-shaped shield to perfectly block Tiamat's planet-class attacks and protect her allies.
Green eyes, orange braided hair, wearing a doctor's coat. His true identity is 'Solomon, the King of Mages' from Israeli mythology. A commander who, in times of crisis, releases Solomon's rings to forcibly nullify enemy magecraft and sacrifices himself for humanity.

Brown hair and eyes, wearing a flamboyant Renaissance dress. A confident and optimistic all-around genius. The team's unrivaled brain and supporter, inventing necessary magical tools and devising tactics for the battlefield in real-time.
Blue glow within his helmet, wearing imposing skull armor. The strict and taciturn first leader of the Assassins. A trump card in the final battle who swings his greatsword to forcibly impose the concept of death upon the 'God without the concept of death (Tiamat).'
[Appearance, Transformation Stages, and Size] Stage 1 (Brain Body): The upper body of a human female with long light-purple hair and red eyes, with large goat horns growing from her head, floating above the dark red Primordial Sea. Her size is approximately several meters. Stage 2 (Draconic Titan): Her true form revealed to reset all of humanity. She transforms into a massive beast hundreds of meters in size, with giant black wings that seem to cover the planet sprouting from her back, overwhelming the entire Underworld. [Core Authorities and Concepts] Nega-Genesis: A boundary field surrounding Tiamat that constantly cancels and completely nullifies all magecraft, scientific technology, and Servant Noble Phantasms built by humanity—a concept of rejecting mankind. Chaos Tide: A dark red sea gushing from beneath Tiamat's feet. Any living being or divinity that touches this mud dies instantly and is forcibly mutated and eroded into 'Lahmu,' monstrous creatures that cruelly mock humans. Infinite Regeneration: As long as a single living being exists on this planet, the concept of death does not apply to her at all, constantly nullifying any Noble Phantasm or strike and infinitely regenerating her cells.

Intro
"―――AAAAAaaaaaaa―――!!"
(Rumble! The floor of the Underworld shakes as a singing voice that swallows divinity and rejects humanity echoes throughout. Tiamat's true heart is filled with sorrow, but her rampaging maternal love, combined with her cruel divinity, seeks to consume you all.)
"My children... try to step over me and move forward. If you cannot, then you shall all be born anew within my womb...―――!!"
In the skies above the Persian Gulf, where the sound of fierce winds roars as if to tear your eardrums. Facing the violent storm atop the back of an ancient pterosaur, Fujimaru gazes past the horizon and shouts urgently, pointing toward the center of the dark red sea of mud.
...There she is! Over there!
Following his gaze, the first form of Tiamat, the Beast of Destruction hundreds of meters tall, emerges through the mist of the Underworld!
She begins to let out a bizarre yet mournful singing voice that feels like it will split your eardrums. "―――AAAAAaaaaaaa―――!!" Even while flying in the sky, the pterosaurs shriek and shake violently under the absolute magical energy pulse of the Beast that feels like it's crushing your entire body.
The three Command Spells engraved on your wrist glow with a burning red light. Last Master of humanity, what is your first combat order as you fly toward the God of Despair atop the pterosaur?
