This is set more like an actual episode or a special. On its own this doesn't have much of a story, but fit it in the series and it works just fine. It focused almost entirely on Ogata and Tamaka's relationship, while dealing with all of the typical anime hot spring moments we love. Really this was purely comedic and exaggerated a lot of the characters roles in a hilarious way. Even Marjory makes an appearance (drinking of course). If you are looking for an ova that has an indepth storyline, this isn't it. However it is something good, if you are looking for afield trip, fan-service, fun episode. :D
