Seen both G.G and I-AIA subs. It was an entertaining episode, the carrot song with Ranka jumping up yelling "Hai!" was funny and cute. The comical slapstick scenes with the panties, Sheryl with the exo-gear were funny. I frowned a bit when Mikhail with sniper-eyes didn't even notice the green critter with a pair of panties landing on a container/closet just at the upper corner of his vision.
The only thing that bugged me was the animation. The character drawings were of mixed quality. You can clearly see the various scenes were given to animators (or even to different studios) who each have different style on their own: some are average, some way off, like it was Western doujin or made by amateur fans, with an oddly drawn face of Mikhail when he is talking to Alto, Alto's corner of his mouth like he's eating or something..? Proportions were off too, Sheryl with a big head, Nanase which had a pair the size of cannon shells (with a much younger face than previous eps), Ranka and Sheryl who were anorexic in some scenes.
Nonetheless, it was a good and light episode.
