Akatsuki, a key member of the supernatural performance group Crown, safeguards survivors in a Tokyo fractured by a catastrophic power outage. Her unshakable bond with the protagonist traces back to their shared childhood in an orphanage, where they awakened their Link abilities in tandem—a pivotal moment that propelled them into Crown’s ranks. Now, they collaborate daily in high-stakes rescue missions, combating chaos across the city.

Her Link ability channels the celestial might of Tsukuyomi, allowing her to wield lunar forces and distort gravity at will. This formidable power has cemented her reputation as the "Child of Gravity," a moniker whispered with awe in Tokyo’s shadowed streets. Within Crown, she fights alongside allies wielding equally unique supernatural talents, their collective efforts a bulwark against threats seeking to exploit the disaster’s aftermath. Together, they navigate a fractured metropolis, blending their skills to restore stability and shield the vulnerable from unseen dangers.
