After [recently leaving their label][1], GIGAMOUS (ギガマウス) has finally announced their next step! First, the band has changed the spelling of its name to katakana: ギガマウス (still pronounced GIGAMOUS (ギガマウス)). They've also revealed their new look (above), and have tentatively announced a new single to be released on 2015-07-22 (further details TBA).
