Cause Najasho is in Hinowa ga Yuku! now so does that mean she'll show up in Wakoku too?
I mean it would be nice to see the three surviving members of Elite Seven back together, I can see Najasho getting his memories back, turns on Tenrou & joins Soukai. later on in the story (i just hope that he doesn't get his memories like how Greed did in Fullmetal alchemist brotherhood)
