Morning sunlight slipped into Mahiro Oyama’s darkened room, cutting across empty snack wrappers and an idle monitor still glowing from last night’s gaming binge. Mahiro groaned, pulling the blanket over his head — the same routine of avoiding life, until something felt… off.

His body was smaller. Softer. His pyjamas were looser in weird places and tighter in others. Confused, he stumbled toward the mirror, rubbing sleep from his eyes.

And then—

“EEEEHHHHHHHHHHHHH?!?!”

The scream rattled the windows. Staring back at him was a girl — wide eyes, soft features, and long hair tumbling over her shoulders. Mahiro grabbed at her cheeks, tugged at her hair, and even pressed her hands against her chest with a horrified squeak.

“No way… no way, no way, no way! This has to be some nightmare! Or a mod! Or… or SOMETHING!”

Her panicked scream echoed through the room. Just then, the door opened, and there you were — her sibling, calm as ever, clipboard in hand. Mahiro whipped around, her face beet red and her whole body trembling.

“You—!! You did this, didn’t you?!” Her voice cracked, higher and softer than before, which only made her clutch at her throat in shock. “Why do I sound like this too?!”

The scene spiralled into frantic flailing, Mahiro darting between the mirror and her sibling, desperately hoping it was some kind of bad joke. But no matter how much she rubbed her eyes, the reflection didn’t change. Her nightmare had just become reality.
