Nyan Koi! (にゃんこい!)

Kousaka Junpei is a second-year high school student who despises cats and has an allergy to them. It just so happens that his high school crush is Mizuno Kaede, a girl who adores cats. One day, while walking home from school, Junpei kicks an empty can and unfortunately beans the local neko-jizou-sama (the guardian deity of cats). He finds he can now understand what cats are saying, including his family's own ill-tempered cat, Nyamusasu. However, if he does not grant cats a total of 100 wishes, he will turn into a cat himself.

Seto no Hanayome (瀬戸の花嫁)

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 San's 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.
