Oddly enough, I clicked on this thread because I knew it was about an anime but surprisingly I was thinking of a completely different anime with "Tsubasa" in the name. Not sure why I ended up clicking, since I haven't seen that one either.
It doesn't seem like my type of anime but I'm willing to give most anything a shot. It's daunting length and the fact it doesn't appear to be dubbed in English are a big turn off for me so I'll probably never get around to checking it out. Not really what you'd call a fan of subs.
