Well, since I'm the first to mark this book as read, I might as well leave a short review. Gate 1 is one of the earliest works of Koike, it deals with a lot of interesting aspects such as psychedelics & hallucinations, time & space travel, human groups from Amazon and the process of acculturation provoked by the Brazilian government; Catholic organizations, etc. G has everything to be an amazing experience, the art is superb, very realistic, but reflecting with surrealistic traits the 'tripping' aspect the author wants to simulate. The plot is almost as good and shows that some anthropological research was done, but unfortunately it has a rushed ending and we're left with no explanations about most of what was really going on, mainly about the "trip", who was having it? The astronaut in cryogenic / the "tribe warrior", who was who, what's the connection between all? There's no moment of enlightenment, the story itself feels like a bad trip. Still, quite at front of it's time (for a 1986 serialization) it's a nice attempt of the mangaka to connect major sci-fi themes with spiritual themes from ethnobotany.
underused elements, priest/space. good art, easy to get through and memorable psychedelia, less polished or, weirdly enough, too structured. wish it let more be implicit.
