After two years from the Initial announcement of Garo: Makai no Hana's movie, Garo Project had finally announced the title of the movie. The title is GARO -Gekkou no Tabibito- (劇場版 ＜GARO＞-月虹ノ旅人- ). Gekkou no Tabibito means Travelers of the Moonlight. In the title the Light (光) in Moonlight (月光) is written as Rainbow.
Mayuri says when Light turns to Rainbow, you will hear the Whistle of Travelers. In the teaser she had also said "Where does that Rail us?". The word rail seems a bit off from the Makai style of the series. There is a possibility of appearance of a Train which would take Raiga and Mayuri to different worlds.
Raiga Saejima Series will finally come to an end. We will also come to know whether Raiga will be able to save his Father & Mother and bring them back to their real world.
