Good news, everyone! Apparently, Dupuis decided to buy a full story of The Heroic Youth of Fantasio. So starting this today, there'll be six new pages in Spirou magazine every week.
And even better: I already have this week's RAWs and I'll try to get the translation out within the next 24 hours.
Looking at the page numbers, I guess the six pages printed in last year's Christmas special of Spirou magazine mark the beginning of the story, while the ones from this year's Valentine's Day special are kind of a bonus. (Though the Octopus café makes a reappearance.)
So look forward to more Little Fantasio. :)
[EDIT: Translation is done. Waiting for my proofreader's reply now.]
