Just an idea I've been playing around with for a Bleach/Freezing crossover.

Just a simple tale revolving around possible relationships Kazuya could have with the Legendary Pandora, the aunts he was never made aware of until just recently, set one year removed from the current point in the actual series timeline. Don't worry there's also going to be relationships between Kazuya and all your favorite girls from Freezing. I'm not leaving anyone out.
