Nice way to deal with Akari and Konatsu

[Pork Okonomiyaki]

These two are the biggest hindrance in Ryoga-Ukyo-union. I never read the manga so I really know nothing about these two aside from what I read on some webpages. Akari is cute, and Konatsu, oh h'es soooo beautiful. They also seems to be really nice people, kinda like Kasumi. That's why I don't like ending with either the evil scheming duo, but don't want them to suffer that much either.

So what could be the most convenient way of eliminating Akari and Konatsu from Ryoga and Ukyo's lovelife?
