I thought the title "Reunion" would have referred to Tanikaze and Benisuzume. Even if something does start between Izana and Tanikaze, his inevitable meeting with Benisuzume again would spark things up. This would give him grounds and guidance for what he should be doing relationship-wise (unless he wants to date a Gauna), but I don't think it'll be that simple. Izana never really struck us as heroine material I think.

Then again (Naruto spoiler: Hinata) wasn't considered seriously for most of the story either.
