I wrote this book from 2011 to 2012. It was originally meant to end after the battle with the Mad King, since it was a book from 2012, after all. Later, readers asked to see more of Dorago in action, so I wrote a bunch of messy bonus stories. Most of them ended up falling apart. Now I've revised the ending, and this is the definitive conclusion. Because of what happened in Chapter Ten, Dorago and Galaxy-kun meet, and the whole family is invited to Infinity Academy. At this point, Galaxy-kun is an investigator working for Infinity Academy.
As for the bonus stories, I've abandoned all the embarrassing old material. But since everyone liked Shinobu's part, I'll rewrite and consolidate it later. Although it won't have anything to do with Dorago anymore, Shinobu will appear in the remastered version of Galaxy. I haven't decided yet whether Tree Sea will be replaced or kept.
