Such dealings with the side characters would occur off-screen indeed. They would be sidestories at the very most, like the shorts that Gryphon likes to put between the Movements in Symphony of the Sword, only dealing with the 'side characters' instead of the mains. This would help quell any readers that are wondering what the hell became of Character X from Y Manga.
Rei is definitely going to be doing a lot of growing up. I've alluded to this in how it finally hits her that her Grandfather is not going to be around forever. Soon she's going to decide to step up her own training towards her goal of becoming a preistess. Traditionally, this means she has to get herself hitched with someone. I think you know what that means for her.
TANGENT:
Something else I've decided to go with is from the manga version where Rei remembers that in her past life she swore a vow a celebacy (sp?) to Queen Serenity. When she wigs out and throws this in Zeke's face, he'll have to take some time out to set her straight. Something along the lines that just because she took a vow in one life doesn't mean she has to follow through in the next - death usually relieves you of such things even if you find yourself in the same role as before.
As for the Oni invasion... I'm going to go with that it was all just for show. They were really just going to open up a chain of resorts for wealthy denizens of other worlds (the Royal Family of Jyurai, for one). Of course, you have to make it look like you've staked your claim. The assurance of Earth's sovreignity is going to be one of the plots in this story.
