Not sure what's going to happen with this one. Is it going to be a rare one where the manga actually ends up with more story than the light novels?
Hopefully the novels themselves can be continued until an appropriate conclusion is reached. I'd be interested in reading them if that's the case.
Finally, after 1000 years and 28 days, the fan translation of vol. 20 was finished and uploaded to Baka-tsuki.
Though I have no recollection of what happened in vol. 19 since it has been so long.
Precure has been around for 17 years, and most of the novels are based on older series, so they're targeted at teenagers or young adults who watched that series when they were little. The exception is the one for Go Princess Precure, which was still only a couple years old when the related novel came out, and that one is in larger type with lots of furigana and easier words.
