As you watch the first few episodes of this French nearly-anime cartoon (dubbed in English), there’s a challenge in working out exactly what’s what in the group of young friends at a boarding school where the resident genius (Jeremy Belpois) interacts with a girl (Aelita) who's trapped in a virtual world which is terrorized by the evil Xana. I suspect I may have missed a few episodes at the start (I started with “Teddygozila”), but it seems that at the end of each successful adventure in the virtual world, the supercomputer take the adventurers back in time to a point of their choosing. It’s kind of cool that things aren’tfully explained, so I hope I don’t later run into the origin episode!
