The <strong>Rokka: Braves of the Six Flowers</strong> books are all mystery novels in an epic fantasy setting.
Things start out pretty simple: Every whatever years, six heroes are marked by the goddess to go confront the demon king. Pretty standard stuff.
The heroes go to meet...and there are seven of them. Then they get locked into an area. Locked room mystery ensues.
That's a good question actually because both are light novels instead of manga volumes which work differently like you said, how much mileage depends entirely on how they can adapt what the characters are narrating, since the writers must take care of not over exposing monologues and what not.
In this case as per Amazon, Rokka's 1st Vol. is 224 pages length, meanwhile Full Dive 1st is 232 in japanese. If something, Full Dive had a bit more material than Rokka.
That's a thing I didn't get though. The first 3 episodes are are pretty good but, after the fourth one it seemed like they just didn't know what else to adapt and started stalling whatever way they could.
I Know I'll probably get shit for it, but I thought ~~it~~ the anime* was S-Class garbage... the novel on the other-hand I've got plenty of praise for. :)
I Would strongly encourage fans of the anime to read the novel, It's got an official English translation too! Please let it be known though that it's been on hiatus for... checks wiki 6 years, 5 if you include the ^^untranslated side story. ):
Edit: *Clarified
Edit 2: Really just adding this edit to express my dissatisfaction in the lack of communication on the authors part, Volume 6 was released 19 days after the anime began airing I hope the reason for this hiatus isn't the author getting scared off by the less-than-stellar response to the anime; I've seen authors go on "indefinite hiatus"s for that exact reason before, but what they really mean by "indefinite hiatus" is "I'm abandoning this because fuck you I guess." Looking at you Kanzaki Shiden.
