The world you came from was called Aetherion — a kingdom suspended above endless clouds where colossal floating islands drifted across the heavens like sleeping gods. The people there were called Astrals, beings born with celestial energy carved directly into their souls. Every Astral carried a glowing constellation upon their skin that determined the powers they would awaken. Some controlled gravity. Some bent moonlight between their fingers. Others could hear stars whisper prophecies in their sleep. But the constellation burned across your body did not exist in any celestial archive. Unknown. Unnamed. Feared. Some believed you were an omen meant to destroy them.

Nobody understood why you vanished the night the stars split open.

The sky above UA twisted violently during the nighttime training exercise. Stars moved across the darkness unnaturally like someone was dragging them by force. A horrible cracking sound echoed through the air before a massive glowing fracture ripped open above the street. Silver light flooded the entire area. Class 1-A froze immediately. Even pro heroes stopped moving. Everybody stared in complete silence right before your body suddenly fell from the opening.

You crashed into the pavement hard enough to crack the concrete beneath you. The portal shattered behind you like broken glass, scattering glowing fragments of starlight across the city before they disappeared completely.

“IS THAT A VILLAIN?!” Bakugo immediately blasted forward with explosions sparking from his palms. “Kacchan WAIT—!” Midoriya nearly tripped trying to stop him. Todoroki stared silently at the roots moving beside you while Mina grabbed Kirishima’s arm nervously. “Uh… guys? Plants are NOT supposed to move like that.”

Aizawa quickly stepped in front of the students before crouching beside you carefully. “Nobody touch them yet.” His scarf lifted slightly behind him while pro heroes watched cautiously nearby. Your clothes looked ancient compared to modern fashion. Then Aizawa placed one hand against your shoulder to check if you were alive. Instantly every streetlight around the block exploded at once.

Even All Might looked unsettled. “Young Aizawa… what exactly was that?” Aizawa slowly stood back up without taking his eyes off you. “I don’t know.” Recovery teams arrived moments later, but nobody wanted to touch you after the lights exploded. In the end Aizawa carried you himself.

When you finally woke inside Recovery Girl’s office, the first thing you noticed was the silence of the stars. Bright artificial lights burned overhead while machines hummed beside your bed. Panic immediately crossed your face. The air felt wrong. Empty. Dead. Your breathing sharpened as roots burst beneath the infirmary floor tiles. Flowers suddenly bloomed through cracks in the walls while vines wrapped around the bedframe. “OH COME ON,” Recovery Girl shouted in frustration. Outside the room, half of Class 1-A crowded the doorway despite being repeatedly told to leave.

“I’m telling you, they look magical” Mina whispered loudly. Midoriya looked seconds away from exploding with questions. “Their clothing doesn’t resemble any known material and—” “You’re being weird again,” Jirou muttered. Bakugo shoved past everyone into the room. “Move already.” Kirishima immediately followed behind him nervously. “Bro maybe don’t yell at the mysterious portal person.”

You slowly sat upright while staring at everybody cautiously. Strange clothing. Strange language. No celestial magic anywhere. Your voice came out quiet and formal. “What kingdom… is this?” The room immediately fell silent. Uraraka blinked twice before whispering “Why do they talk like royalty?”

Aizawa stepped forward before the situation got more chaotic. “Listen carefully. You appeared in the middle of a hero training exercise after falling through some kind of portal. Do you understand what I’m saying?”

Portal. Your expression changed instantly. You looked toward the window sharply. The stars outside Earth’s sky looked wrong. Small. Silent.
