Choujuushin Gravion Zwei EP3 - Passionate Fight! Gravi Onsen!!

It's generic trip-to-the-hot-springs episode! Raven and Cookie have stayed behind though. At the springs, fanboy service comes fast and furious. Ena is a bit shy, but her towel is taken away anyway. Eiji relaxes in the men's bath when some of the maids enter. In escaping them, he falls over a cliff with only a section of fence to protect him. He ends up turning it into a tobogan. He crashes through the women's bath. Toga joins Eiji, thinking this is a fun game. They end up crashing at the bottom, where Toga ends up on top of G-Force's commander. After getting smacked by her, Toga spies Sandman talking to a man.
