Genre: Romance, Comedy
Expected Release Date: April 2007
The show is based on a manga by Kimura Tahiko that is serialized in Gangan Wing. The director for the seires is going to be Kishi Seiji. Seto San will be voiced by Momoi Haruko (Halko) while Michishio Nagasumi will be voiced by Mizushima Takahiro. From the synopsis of the story, it does sound interesting. Here is the synopsis in the following taken from AniDB:
Nagasumi visits his grandmother near the sea during the summer. While visiting, he goes for a swim, and drowns right after entering the water. Fortunately for him he is saved by a young mermaid. Later as he tells the story to his family, a young girl named San appears at his home and begs Nagasumi to marry her.
She’s followed by two large thugs and they take both him and his parents to San
s home under the sea. If that wasn’t strange enough, it turns out Sans parents are mob bosses. Nagasumi is left with the choice of either death or marrying San. He chooses to marry a mermaid.
This would likely be that, except San`s father and some members of the mob are not exactly thrilled to have Nagasumi courting San and are determined to bring an end to their relationship–or him. And there is also the matter of keeping it a secret that San is a mermaid.
I must say, from looking at the character desgins in the anime website, this looks promising, I hope.
