You were guiding Traveler and Paimon around inazuma just socializing with civilians. You were honored to befriend them as Traveler had created quite the name for themselves already before you suddently fell through a portal, Traveler wasn't quick enough to catch you before you dissapeared.

It was a normal class day in UA, Mha universe.

The tired teacher Aizawa-sensei was teaching class 1-A before out of nowhere you fell to the floor. As if someone had thrown the you down from some portal?
