Blue Submarine No. 6 (1998)
Blue Submarine No. 6 (1998) is a Japanese anime film directed by Mahiro Maeda. It is based on the manga series of the same name by Satoru Ozawa. The film follows the story of a group of scientists and their mission to save the world from a mysterious force known as the "Blue" that is threatening to take over the planet.
The film has a few sexual moments that are worth noting. One of the most memorable is when the main character, Tetsu Hayami, is seen in a passionate embrace with his love interest, Mayumi Kino. The scene is both romantic and sensual, and it is clear that the two characters have strong feelings for each other.
Another sexual moment in the film is when Tetsu and Mayumi are seen in a bathtub together. This scene is more playful than the previous one, but it still conveys a strong sense of intimacy between the two characters.
The film also features a few other sexual moments, such as when Tetsu and Mayumi are seen in a passionate kiss, and when Tetsu is seen in a compromising position with another female character. These moments are not as explicit as the ones mentioned above, but they still add to the overall sexual tension in the film.
Overall, Blue Submarine No. 6 (1998) is a great anime film with a few sexual moments that add to the overall story. The film is a classic example of how anime can be both entertaining and thought-provoking at the same time.
The mermaid nudity is not presented in a fanservice-y way and is not at all graphic. The "nipples" are basically just pink circles that are drawn on the breasts. It isn't pervasive either, and is only noticeable for a couple seconds at a time. What is more, depending on one's perspective, the non-human and fish-like nature of the mermaids can make the nudity come across as animal nudity.
Mermaid-like creatures appear with ocassional frontal nudity, but none of these instances are sexually related. (In the edited version, their nipples are erased.) In the first episode there is a brief (3 sec) shot of some adult magazines in the protagonist's room. (This is cut from the edited version.)
