It's been a while since Maple and Sally enjoyed some adventures with just the two of them. The girls head out to search for a secret dungeon in the sky. They discover some amazing scenery and even take commemorative photos, but then Maple comes across a girl with lightning-based skills. Apparently, she's the guild master of an up-and-coming new guild and intends to knock Maple Tree off their pedestal!
