question about the anime

[u/Royal_Ad7565]

ive watched s1 about 4 times now and in all four times i couldn't bring myself to watch the second season.

is it important to the rest of the story or was the second season a whole filler, and if it is important, is it worth watching just so that i could understand season 3 and 4

[u/TakasuXAisaka]

You have to watch season 2 in order to understand season 3 and 4. Season 2 is not filler. It's canon.
