Some works: "ok, with these last four pages for part four this chapter should be over, time to split the next chapter in other four pieces to release one a month!"
This one: "ok, so with these next 16 pages I finished part 10 of this chapter. ...wonder if I should make part 11 or a new chapter? ...why no, I don't think these should be split into separate chapters with their own numbers, they are a quick thing in the novel so it would not be fair, why do you ask?"
...so, is the Freeza 5-minute to Namek Exploding fight over now?
Got a feeling that this manga might be like those kind of manga to promote LN such as Ningen Fushin.
Someone mentioned this was near the end of the first light novel... of a series that released volume 16 already.
