Okay so I'm trying to figure out how many episodes are in one season of Fairy Tail so here's my number count.

Season One-48 episodes
Season Two-48 episodes
Season Three-54 episodes (The season I'm currently on cause I'm waiting my time for dubbed episodes)
Season Four-25 episodes
Season Five-19 episodes (and counting)

Jesus Christ my mouth is now dry from counting ever, flipping, episode. And Ouran is technically a two season anime. On Netflix they put both seasons together to just make it one 26 episode season.
