The upcoming Fairy Tail game is aiming to be everything fans of the series want. That's going to include some moments of fan service as well. For example, there's a scene in which Erza briefly appears in a yellow bikini, which is a famous moment from the Grand Magic Games arc of the series. In an interview with Comicbook.com, producer Keisuke Kikuchi says fans can expect similar elements throughout the game.
"Obviously that's not something that this game is about or focuses on, but we're trying to be faithful to the original franchise." There will be sequences like that one, where it's the same in the manga and anime that you'll see some bathing suits and there are a few more in the game."
