DearS - Season 1 Episode 10 : We'll Have An Orgy-Nii 2004

While browsing the market, Miu participates in a lottery and, unknowingly rigged for her, wins the top prize; four tickets to a newly opening bathhouse. She invites Takeya, Ren and Neneko who all agree to go; Nia following. During the stay, when separated into unisexual baths, Ren goes searching for Takeya; Nia flying through a high window and passing out from the fall. With Yoshimine distracting the commotion, the group escapes the building. Seen aboard an incoming flight is Harumi and Natsuki.
