Blue Fireflies

Aoi was a normal eight year old girl, going to a normal park. She and a few others gather a group of kids to play tag with, and they decided to call themselves, Akatsuki. However, they wander off the park to find Tobi, the self-proclaimed "good boy," when they find a glowing purple mist. Being the curious child she is, she runs through it, and so does the group.
Good news - The purple mist felt like raindrops on her skin on a blazing hot day.
Bad news - It transported them to another world without chakra. Oops. Not to mention, Aoi gets separated from the rest of the group. Double oops.
