Ioanna Starfall drowned as her village was set ablaze by dragon. I woke up in her body and refused to become a heroic Valkyrie. I've got far more important things on my to-do list. You see for a biochemist like myself reborn in the land of Nordic cultivators and giant monsters there's a whole new world of science to explore and magical creatures just waiting to be dissected. Also, nobody suspects that I'm a witch. Mwa ha ha.
