So, no one knows who Princess Inada is, or why she and I have a problem?
The closest thing I can find is Kushi-inada-hime from the legend of Yamata no Orochi. No clue as to why she has a problem with you (though technically it would be Minoriko who's being scolded).
As far as I know, that's the right Princess Inada, also known as princess Kushinada or Kushi-inada.
(I think it's
Minoriko that's doing the scolding. Since it's 稲田姫様
に 叱られるから and Mioriko is that Princess Inada.)
In Touhou we know her as Princess Inada or as Aki Minoriko, she's concerned with the harvest of crops, mainly rice.
(This can be seen because when Princess Inada was saved from the Yamata no Orochi, she was actually used as a sacrifice for a successful harvest.)
Although in Touhou lots of fans see her as a minor god, but since she's in charge of what humans harvest she's actually one of the main gods that common farmers and families would care about. (Possibly having even more faith than Kanako or Suwako)
Why such a giving god would have a problem with you?
Beats me, did you say something insulting to the Aki sisters? Or maybe you didn't respect your food when you ate it?
Did you possible leave left overs and didn't feel sorry for doing so? (They say there's a god in every single grain of rice!)
Since if Minoriko has a problem with you, that means that you won't get to eat good rice, that includes fried rice, whit rice, rice cakes, and even sushi!
