The first volume contains the short manga “Fairy Tail” that Mashima would eventually turn into his Fairy Tail serialized manga.
The manga is the third and last installment of Shibano’s Fairy Tail Gaiden spinoff series, which also includes Fairy Tail: Twin Dragons of Sabertooth and Fairy Tail : Rhodonite.
Kyōta Shibano’s Fairy Tail: Lightning Gods (Fairy Tail Gaiden: Raigō Issen) manga is a spinoff of Mashima’s Fairy Tail manga.
Kodansha shipped the one compiled book volume for Fairy Tail: Lightning Gods in Japan in November 2016.
