Well, what is usually referred as the second run is from 2014, that's the one that came out in 1020p for example. The previous run was The first run, which opened with Lucy joining Natsu, and ended with Natsu fighting Rouge and Sting solo at the tournament while Gajeel discovered the dragon graveyard. The second run continued with that, the final day of the tournament, then the dragon invasion, and ended with the Tartaros arc, where they fought a guild made of Zeref demons, Kyouka in this game is one of them. The second ended in 2015. Between there was a short named Fairy Tail Zero, it showed how FT was created by Mavis a 100 years prios. Then it was the Final Series, which began in 2018. The MC of this game, Gust (August) was introduced there, as well as Irene. English dub versions came rather late though, maybe you watched that?
