It just sucks that no one can ask Takaya what and why since that is seen as disrespectful for his culture. I find that frustrating. Still, I think it's rude that he didn't make an announcement and give an excuse. It's almost as bad as standing up a girl you asked out on a date. The point is, he could have said anything he wanted, it doesn't have to be about his personal life. At least than we'd know not to expect anything. But since it's taken this long and what ever chapters he was working on is in production hell. It's a bit obvious now.
