If they all had one, what would the original Lyoko character's diaries look like?

Yumi, Jeremie, Aelita, Ulrich, Odd, and (sadly) Sissi star in this diary POV series.

And, to add more interest, this series takes place after 'The New Kids on the Block' series, by yours truly...

So, add Brianna, William, Andrew, Kazuya, and Emily's diaries in, and what do you get?

An interesting series.
