Well, seeing as how I didn’t really plan out a specific ending or episode count for my series, it will probably be as long as it has to be.
I do though, know how many arcs my series will have (for the most part).
There’s going to be 2 arcs plus a mini one in between if it calls for it. Then there’s a time skip where there will one arc plus 2 which I don’t have any detailed ideas on what I should exactly do for them. Then after that I plan on ending the series with mc getting married and becoming a dad.
There are ideas for potential sequels and even spin offs that take place while not taking place in the series’ universe are still apart of the continuity via a multiverse. (Don’t ask) I’ve also thrown around the idea of having the series not after the mc graduates high school and instead have it continue whilst he’s in college. Mostly because, with shonen from what I’ve seen, you rarely have the series continue after the main character becomes an adult. And in some cases when they do continue with the mc being an adult, it’ll mostly be them getting married and starting a family, with his of her son/daughter taking the role as mc. Nothing wrong with that persay, but life doesn’t end after you get out of high school. Personally I want to see how my main character would handle college especially since I’m currently in college so trying to relate to a character who’s in high school or middle school is almost impossible now that I’ve grown up.
All of this could change though so I wouldn’t be surprised if the info here ends up being irrelevant
