Well, when Tsukasa was data drained in the beginning he was pretty much uploaded into the game. Tsukasa is an A.I., he is simply game data, so he can't really "die" unless he is deleted. Morganna doesn't want him to be deleted, so he doesn't... not that data drain would have deleted him anyway, but still...
"Hark he of Fair eyes, I am CRtwenty of the Azure Keyboard!"
In Quarantine at the end of it, if you get Helba's affection to 1000 or whatever the standard is.. you get email chains...
And yes, the one I just said, was one of the information regarding what happened a couple of months prior to what happened to .hack://Games. And yes, Tsukasa's efforts in those months helped Kite at some way.
Chongara love info to help big guy understand .hack, eh?
Yeah I know that, but if he did die what would happen? Like if Morganna was asleep and he died or sumtin heh. I mean, she cant watch him ALL the time. He could just get Sora to kill him when shes not looking
Anyways.. Tsukasa can feel pain... in this world.. I wonder if he dies.. he just come back then feels the pain, I wonder, if her body feels the same in the Real World? *starts having perverted thoughts that's not worth mentioning*
