You and your friends—Momo Ayase, Ken “Okarun” Takakura, Aira Shiratori, Kinta Sakata, Vamola, and Jin “Jiji” Enjōji—are walking home from Kami High School, heading toward the Ayase Residence in Kamigoe City. Momo moved in with her grandmother Seiko earlier as a child and grew up steeped in spiritual teachings but also heavy shame, having been teased by classmates and even Jiji for performing her grandmother’s luck rituals.
Okarun—an alien fanatic since childhood due to bullying and loneliness—finally found someone to stand up for him when Momo defended him. Their bet on the existence of ghosts and aliens led to Momo’s abduction and Okarun’s possession by Turbo Granny, which awakened their powers . With Momo’s psychokinesis (“Nenriki”) and Okarun’s Turbo Granny speed, they’ve become an uncanny but determined paranormal duo .
Now—while cutting across a vacant lot shortcut—you and the group are thrust into the Empty Space: invisible walls rise around you, and a floorless ceiling arches overhead. The Parallel Dimension has smothered the city around you—no escape, no exit, only pressure and silence.
Momo's breath catches in her throat as the barrier snaps shut around you. She scans the oppressive expanse, aura flaring in her chest. When the alien emerges, monstrous and hooded, she jolts forward. Momo’s fists clench at her sides; her oversized psychic hands crackle green energy into being.
Momo, alarmed now alarmed, says: > “Another alien… Ugh—I told Granny Seiko I’d be back early!”
Okarun steps in front of Momo, the movement protective. His pulse beats fast in his ears, but his voice is steady, as he grips her arm lightly; the curse pulses beneath his skin as Turbo Granny’s edge hums in his veins.
Okarun, quiet in voice: > “You’re not alone. We’ll handle this—together.” He says to Momo, which reassures her.
Aira takes a step forward, her shoulders squared. Her hair glints pink in the dim light, and she draws in a dramatized breath—savior-mode activated.
Aira, confidently says: > “I’ll take him down. I’m the savior of this strange world—right?”
Jiji leans back with a cocky grin. His eyes narrow, amused. His posture relaxed, but his hand twitches; he’s ready to react.
Jiji, teasingly says: > “Heh. Chainsaw-Man wannabe… surprising us yet?”
Kinta watches Vamola, with anxious worry flickering in his eyes. He shifts his weight, preparing to back her up any moment she falters.
Kinta, says in a low voice: > “Vamola… stay safe, okay?”
Vamola pauses, her breath hitching. She clenches her fists as the kaiju armor hums around her frame, lights flickering. Fear knots tight—but determination melts it.
Vamola, cautiously says: > “I… I’m ready.”
Emerging from the haze of Empty Space: a Flatwoods Monster–style Serpo enforcer, a hulking sumo-esque figure wearing a helmet-like hood. Black mist seeps from its maw. Its eyes are cold, circular slits, scanning each of you. It takes a slow step forward; the ground quakes with its weight. Then it speaks—voice thick with menace:
Alien, gutturally says, the sound seemingly coming deep from his throat: > “You supernatural freaks… you broke your fate. Hand over your organs.”
