I'm glad Akari finally got some closure with Minami, and that he finally got some characterization.
Ultimately, I think that he inability to communicate how she feels to Jirou and how she treated him before will be her undoing, and that Shiori will probably be the one to make it, at least for a little while.
Ultimately, I'd say marry both of them, but I think that Akari reflecting a bit and realizing that she should have made her affections clear earlier and that she wasn't just teasing him or harassing him, which becomes her undoing.
Whatever, harem end is always best choice. I still say pair the wingmen, too.
