A Certain Down-and-Out Vampire Lady

I can accept transmigrating after buying tofu at a stall. I was planning to live an ordinary life as a little girl. But then you tell me I'm an important person who has to take part in the main plot? Fine, I guess I'll just have to take my one and only follower and go monster-hunting with the hero. This book is also known as The Little Girl with Level-One Gear and Maxed-Out Equipment, and Her Max-Level Follower with No Gear: A Co-op Adventure
