Response 1: he needs to suck it up and get to work. And remember the Code.

Response 2: that's what he gets for not spending experience to eliminate the "Life Sucks" flaw.

I'm spending too much time on games...

I'd say rather that Ryuu was the first to accomplish his dream of fighting with Serizawa, then taking care of GUYS, and killing kaiju sometimes with Ultraman sometimes not. The others fulfill their dreams a year later after returning to their lives. Same as Ryuu, what they do after that is up to them. Konomi still teaches, Teppei still in med school, well, Marina can keep competing or start trying to do commercials, George can try to do a Shiseido commercial, etc.

Or Ryuu could always try to prep up for the next kaiju invasion since it sounds like Sakomizu was prepping for quite a while. Surprise! He's in the next Ultraman series.

"Aihara taichou" may be more correct, but I like "Ryuu taichou" better. ^_^

Ryuu's old life got blown up in the first episode...

It seems a little unhealthy, IMHO, that his life does not seem to exist outside of GUYS.

...and his rebuilt life all goes home at the end of the series, leaving him to put everything back together yet again.

Does he really have to put everything back together again? I probably don't understand what you mean, but I just think everything returns to normal at the end, mostly. Lives, for all of them, seem to continue from where they left off at the beginning of the series.

No kidding. Even more than Mirai, he needs to get a life. Maybe that's part of why those two are always hanging out together -- both of them put work at the center of their lives, and don't have a lot besides.

Does he really have to put everything back together again?

Going back to work being his life... it seems to me that yeah, he kind of does. He can't go back to doing what he was doing before the series started (unlike everyone else), since that all got blown away in the first episode.

Though I suppose by the same token, it could be argued that he never left his old life (i.e., GUYS), so he has nothing to leave and go back to either. It just seems to me at the end that it would be a bit lonely.

OTOH, based on info I dug out on the Nagoya Premium Stage, Konomi and George are still around. (Don't ask me how George has a soccer career in Spain and still is working full time with GUYS Japan.) So maybe everyone isn't so gone after all.

Oh, and I like "Ryuu taichou" better as well. It only occurred to me when I was proofreading something that technically, it's not correct. But I'd still written it as "Captain Ryuu", and hadn't batted an eyebrow the first several read-throughs.

I agree with sennetari, I prefer Ryuu-taichou, however inaccurate. After so long, he's just "Ryuu" to the viewer, so anything else feels wrong and distant. It's most likely just force of habit/comfort.
(Writer's block is awful and enraging, here's to hoping it goes away soon ^^)

Ah, that's really depressing. Probably unintentional on the writer's part, but still bad. Granted, by the end Ryuu seems willing to face any challenge on his own, and with his friends' service done, he can't exactly order them to stay. I'd like to think they keep in contact and hold gatherings (with the exception of Mirai, I suppose) every now and then.

Per stuff I've read about what happens in the stage play that happened in Nagoya back in April last year, it seems that Konomi and George are still around. So maybe it's not as quiet around the Phoenix Nest as I first assumed. :)
