Jill, the legendary warrior, started her adventure by tripping into a portal by accident.

Jill wasn't expecting any adventure to come to her life after she dropped out of high school two years ago. At best, maybe she would have a wonderful love story. After two years of having zero contact with anyone from school, including her friends, one of her friends sends her a letter asking for help. Curious, Jill goes to where the letter tells her to go and, after walking around, finds an old abandoned shrine. As she explores it, she stumbles upon a pond that strangely looks like a portal. Having common sense, Jill turns around to walk away...

....then trips and falls in. When she comes to, she finds herself in a mystical beautiful garden in the middle of a black void...

....and meets a carefree cheery quirky girl named Chaersie who guards this place. Chaersie, after she had enough fooling around with Jill, tells Jill that she has come into contact with the Yeither, and, as such, must now either stay here in the garden or go out and either hunt down Monseuteo, monsters from multiple dimensions created by The Garden Of Sinners, or risk being attacked by them while she is walking alone.

Because Jill doesn't want to be ripped to shreds and wants to find her friend, she decides to hunt the Monseuteo. When she makes that decision, she learns that, in a certain part of the world, magical girls do exist, and she is now one of them! Yet, she quickly learns that quite a few magical girls are psychopaths who have been alive for a long time, or their own magic has done something to their brain. Yet, determined to save her friend, Jill doesn't back down. As she fights, she soon learns that all of her friends but one have disappeared...

....and that she isn't really a good warrior either. Oh, and she has a dysfunctional team. No joke, one of them is a masochist, the other a sadist. The other two aren't better either. One of them is a jerk and the other one may or may not be a serial killer. Still, Jill has a mission and a job to do.

And so begins Jill's luck-needed adventure as a Ryōshi, a fancy name for a magical girl, a hunter of monsters, to try and find her friends and take down The Garden Of Sinners.
