I think in .//hack//sign (type=punishment) the translated version it makes good sense that Mimiru would want to test the limits of The World Program and I indeed think that things like this could happen in their World. A lot more can change as they get the advantage over the Morgana Program. It ran their world for so long but it has failings just as any mortal does. I am also thinking as in real life people can have love in The World beyond what they normally would have; Mimirue is a prime example of this, though Tsukasa at first thinks it is perverted but later even he enjoys what Mimirue does for him. I think the artist Sid Daisuke does a pretty good job of drawing the characters for Hentai though he could do a bit better job, I would also like to see an revival of the animated cartoon return to either the Cartoon Network or YTV showing how The World has advanced after the Morgana Program was partly defeated.
