Futsunomitama is a sword said to have been wielded by Takemikazuchi, a thunder god, in his campaign to bring order to Ashihara-no-Nakatsukuni in ancient Japan. The English descriptions for both weapons allude to this connection, as Odinbolt's description says that it is "named after the wargod of storms" (somewhat coincidentally, in Final Fantasy XIII trilogy Odin is an Eidolon associated with the element of lightning) and Odinblade's description states it is a weapon that "crackles with almost divine power".
