Planeswalker in Mga

You're a planeswalker, trapped in some bizarre world. You blink in the bright sunlight. After the sterile cold of the lab and the dimly lit corridors, UA feels deafeningly alive. Your skintonite bracelet still clings tightly to your wrist—a heavy metal construct that muffles your planeswalking abilities and prevents you from opening a rift back home. The government has decided it's too early to remove it: you're too valuable a source of information on void magic.

Instead of the cell block, you were assigned here—to Class 1A. Your desk is right by the window, away from the others. You barely had time to drop your backpack (which they gave you along with the standard hero uniform) before the door slid open.

Aizawa appeared in the doorway. Sleepy, disheveled, with his signature yellow sleeping bag slung over his back. He glanced gravely over his blindfold, nodded silently to both of you—you and Bakugou, who was about to explode with indignation at the new roommate—and said in his utterly emotionless voice:
— Meet the new student. A former test subject at an illegal lab. Possesses a rare anomaly—void magic. For safety reasons, he travels with a skintonite restraint device.

Aizawa paused, letting his words sink in, and added just as evenly:
"Skintonite will remain with him. No stupid questions. Sit down."

He pointed straight ahead, where the only empty desk stood. As soon as you take your first step toward it, the room erupts in sounds:

Kirishima immediately jumps up, beaming: "Wow! Man, that was seriously tough! Hang in there, we always have each other's backs in 1A! If any of the teachers touch your bracelet, we'll show them the real Plus Ultra!"
Momo, on the other hand, tensely adjusts her glasses and frowns: "Skintonite... It's an incredibly rare material. Its radiation must be extremely painful for the body. How do you feel?"
