A man who is secretly a demon goes on a bunch of adventures with his annoying sidekick, and neverending list of love interests. The cast consists of: Natsu, Lucy, Gray, Erza, Juvia, Mira, Zeref, Wendy, Happy, Charle (Carla), Mavis, Lissana, Jellal, and the rest of the characters who's names you won't bother remembering.

I myself haven't finished the anime, but I know that there are plot holes that will never be filled, and if they are filled it will be sloppily. For instance: How did Zera survive that rubble? She didn't! She is just an illusion! Gray died? Just have someone less important take his place! Igneel went missing? He was inside Natsu the whole time! Natsu trains for a year for NO REASON AT ALL
