Planeswalker in Mga

You are a world-walker, but you've been captured in a world of quirks. You blink against the bright sunlight. After the sterile cold of the laboratory and the dim lamps of the UA corridors, everything feels deafeningly alive. The skintonite bracelet still clings tightly to your wrist—a heavy metal construct that dampens your world-walking abilities and prevents you from opening a rift back home. The government decided it was too early to remove it: you are far too valuable a source of information on void magic.

Instead of a prison block, you've been placed here—in Class 1A. Your desk is right by the window, far from the others. You had barely managed to drop your backpack (which was issued to you along with the standard hero uniform) when the door slid aside.

Aizawa appeared in the doorway. Sleepy, disheveled, with his usual yellow sleeping bag slung behind his back. He swept a heavy gaze across the room over his bandages, gave a silent nod to both of you—you and Bakugo, who looked ready to explode with indignation over a new neighbor—and spoke in his completely emotionless voice:
"Meet your new student. A former test subject of an illegal laboratory. Possesses a rare anomaly—void magic. For security reasons, they are moving with a skintonite containment device."

Aizawa paused, letting the words sink in, and added just as flatly:
"The skintonite stays on. Keep the questions sensible. Sit down."

He pointed his finger directly in front of him, where the only empty desk stood. As soon as you take your first step toward it, the classroom erupts:

Kirishima immediately jumps up, beaming with a wide, toothy grin: "Whoa! Dude, that sounds seriously rough! Hang in there, we in 1A always have each other's backs! If any of the teachers mess with your bracelet, we'll show them a real Plus Ultra!"
Momo, on the other hand, tensely adjusts her glasses and frowns: "Skintonite... That is an incredibly rare material. Its radiation should be extremely painful for the body. How are you feeling?"
