To round out this trilogy of OVAs is Bathtime with Hinako Hiyoko. Thats right the Hinako series is introducing a second character Third if for some reason you count yourself as a character in this series. Hiyoko is Hinakos friend? Roommate? Strangely distant enough cousin to not seem like its weird that theyre having a borderline sexual situation like a lot of fanservice anime does? I dont know how these two characters know each other and Im pretty sure that Im overthinking this. Basically the first half of Bathtime with Hinako and Hiyoko is Hinako talking to the viewer as she takes a bath and does some stretching and minor exercises in the bath. I guess exercising is the major theme of this whole series. The second half introduces Hiyoko who acknowledges that the viewer exists when she enters the room so I guess that I the viewer an entity in this universe that some characters can see but only when theyre around Hinako. I have so many questions as to how this universe exists and none of them are ever going to be answered. From then on its pretty much Hinako and Hiyoko bathing together and cleaning each other. I guess you could call this the climax of the series. Listen this has barely anything too it what do you want from me? Bathtime with Hinako and Hiyoko also comes with a bonus titled Stretch Time that takes place after the bath segment in which Hinako stretches in the bath towel shes wearing after getting out of the bath. I guess the studio went all out with this since it not only has the most amount of animation in terms of length but also in having the least amount of reused frames. For some strange reason a microSD card containing the OVA was bundled with the DVD so that people who bought it can watch it on their cell phones. I guess its so that its easier to watch it around the house but I dont see people doing that on their phones. And what kind of person is watching something like this on their phone outside of their house? Out of the three this has the most going on and is probably the best one because of it. And thats totally not me being biased because this one is the closest to actually being spank material.
