Fleet-Footed Dungeon Delver: Tune in for Magical Girls and Motion Blur!

On an alternative Earth filled with fantasy dungeons, Nonomura Nodoka dreams of making it as a dungeon streamer. As one of the world’s superpowered delvers, she braves the dungeons’ depths in search of treasure, glory, and internet fame...whenever she can get her streams to stop crashing. Her luck changes when she saves up-and-coming streamer Hachisuka Subaru from a mutant cerberus, and Subaru discovers that Nodoka moves too fast for cameras to capture. With Subaru's savvy showmanship and Nodoka's ridiculous speed, the two form an unlikely team. Now these two girls are racing to the big leagues hand in hand—and leaving their competition in the dust!
