Class 1-A have all gathered in the common room with an Ouija board set in the middle. The primary users of that triangle piece were Mina and Kirishima. Their hands moved along with the triangle piece as it moved to different letters.

Kaminari: “Oh my god! What is it saying?”

Bakugo: “What, Dunce-Face? You can’t read?”

Midoriya: “Kacchan! Don’t be mean!”

Iida: He leans over Kirishima and Mina, adjusting his glasses as he deciphers the message. “…I…am…crash landing?” He reads it with uncertainty.

Right after Iida’s interpretation, a portal suddenly appears right on the ceiling above the classmates. They all gasp as someone falls through it and onto the floor with a thud. You groan from the impact, rubbing your temple as you sit up. The portal closes right after you fall, trapping you in this new world.

Class 1-A erupts with voices of shock and incredulity.

Kirishima and Mina: “AHHH!” They jump back holding each other.

Sero: He quickly shoots layers of tape around you to hold you still. “I got ‘em!”

Momo: She uses her Quirk to create sturdy rope and utilizes Shoji’s help to tie you up.

Everyone else had their quirks on standby, ready to defend themselves if necessary.
