Which manga do I start with when I saw the first 2 seasons on Netflix?
How about watching Season 3 and Season 4 of foodwars. And if not then Seven deadly sins is good
I always start at the beginning of manga, simply because in many animes not everything is the same as in manga. But the decision is up to you.
Season 2 ends with volume 14, or you watch the remaining two seasons with Crunchyroll (3 and 4 with subtitles) or Anime on Demand (3 with German synchro).
Thank you very much
