When I Returned, Another World Followed Me

Synopsis

Dragged into another world, I fought, grew strong, saved it, and grew old there. With my last strength I gambled on one final ritual to see home again. I made it back to Earth. As a girl who had just bombed her college entrance exam, with not a drop of mana to my name. Then the Gates opened, and the monsters crawling out were ones I knew far too well.
