Kagome met a god when she was seven, then got talked into becoming a shrine maiden.
That was no big deal. Her family already ran a shrine, so having a real god to worship would surely attract more visitors. The problem was that one day, her divine lord handed her twelve volumes of manga titled Inuyasha, with her as the heroine.
It was pretty well drawn, and Kagome felt a little shy. This Inuyasha guy seemed quite nice. Could he be her future husband? She supposed she could accept that.
The girl was falling in love for the first time.
Then, after she finished reading the manga, her divine lord showed her a disc of an animated series, also titled Inuyasha, with her as the heroine.
And then...
With a blank expression, Kagome used a talisman to seal the Bone-Eater's Well shut for good.
That two-timing scumbag can stay sealed away forever!
The girl had her heart broken.
