the only thing i really remember from them is "DAAAAATAAA DRAAAIANNN!!!!" that and kids trapped in the game
nobody ever shouts data drain in .hack//sign lel
come to think of it, kite doesn’t yell it in the videogames either
you must be thinking of legend of the twilight or something i haven’t seen???
Also the only person who ever gets trapped in the game is Tsukasa, nobody else :-)
probably legend of twilight. Shugo does shout data drain like a DBZ character
