Though our protagonist are Sam (Son of Gray and Juvia) and his companion NiNi(a fuzzy creature that looks like a fuzzball penguin with a tail), Metallica(Daughter of Gajeel and Levy) and her companion Haru(a mole with a skill with weapon that he made), Thomas (son of Jellal and Erza) and his companion Velma (a hawk-like bird that is solid but at the same time. He got her when she was in an egg from a mysterious being as a reward), then last we have Nashi (daughter of Lucy and Natsu) and her companion memmy/mem (Son of Charle and Happy).
