Judging by the opening and certain scenes in this episode alone, it certainly looks like this anime is gonna pass up on ANY chance for fan service, which is no surprise since it mainly belongs to the Harem + Ecchi genre. Pretty decent first episode besides that, it's decently paced for a rom-com + sci-fi. The voice acting is pretty natural, and the animation and art style are pretty comfortable. The humour definitely landed for me, which was great. Pretty predictable plot though.
