Most of the fanservice comes from the blonde middle child Nene who dons a skimpy pink battle suit throughout the series and is easily the only reason why anyone should watch this other than that most of the female cast has some pretty minor service. One noteworthy thing to mention this show went with blank nudity. However June the female Mech has a scene where she is in a giant bathhouse and has some barely visible nipples But shes a giant mech.
