By the way, the one who was interviewing Ryukishi in May was:
Oota Katsushi
http://en.wikipedia.org/wiki/Katsushi_%C5%8Cta
He's an editor for Kodansha, not Ryukishi's editor. Unfortunately. Not sure how he's related to Ryukishi, but it's probably for something like the interview itself for a magazine. (Square Enix published the manga, not Kodansha, so it's not that. I just grabbed a few off the shelf to check just now.)
Of course the real problem is Ryukishi not having an editor. 8) ... Although, does he have one for Higabana? I sure hope so...
