So now we got a male Hakurei(maybe, probably some ancestors that got sealed or something) joining the fray.

Someone care to explain to me why are they doing this?
I don't know about the other guys but having Byakuren fight Myouren is going to be painful to her. But the worst would have to be if Ichirin somehow have to fight Unzan. That would be really hard to read considering in canon they're almost like a lover.

It was hinted at when Rinnosuke had a flash back involving Heida Akyuu. She said something and he decided to make her wish a reality. Which is why Heida Akyuu is a lot more important then one can imagine.
