Well in this the characters are in a game so that could explain the way they are wearing less clothes than normal because for some reason in most video games, less clothes = better armor.
As far as which anime is first it is .hack//sign that is the first in the series.
Thankfully it seems FUNimation is only charging around $25 or so on righstuf for the series so it wouldn't be too bad. Clocks in at around an hour and fifteen minutes. Though according to the review the extras are pretty tame.
Awesome.
.hack// is amazing. Female Kite is hot too ;)
Interesting review. I like Hack .. thanks for sharing this out.
I would totally get this if it wasn't just 3 episodes
Had no idea this was canon until yesterday. I must watch this!
