Makoto Suda has a secret. Trapped in a dual identity, Makoto plays the role of mother to stepson Takashi at home. At work he plays the ordinary salary-man, caught in a two person love triangle with his other self and coworker Natsumi. The story follows Makoto's attempts to balance his life as he waits for the perfect moment to "come out" of his predicament.

The story is about Hare, a 10 year old boy who lives with his mother Weda in a small village in a very strange jungle. Hare's mom is a bit of a "party girl" and likes to sleep in all day and party with her girl friends all night. Things change one evening when Weda comes home with a little "playmate" for Hare, a pretty little girl named Guu. But when Hare wakes up the next morning, Guu has "transformed" into a sullen, nasty and sarcastic joker who takes great pleasure in making Hare's life utterly miserable. Guu can also swallow anything, and regurgitate it whole. Guu also seems to have various magic powers, which lead Hare to consider her a demon of some sort, but he can't convince most other people of that.

From Okazu:

Mermaid Line is a collection of stories that ran in Yuri Hime magazine. They are collected together as short mini-series, done in an episodic, almost soap-opera-y way.

In "Megumi and Aoi " Megumi confesses to her friend Aoi that, despite her ungainly swimming, she feels as if she is a mermaid. Aoi finds herself fantasizing about being the prince to Megumi's mermaid, but Megumi runs to the arms of a boy, trying to put a beard on her feelings.

Ayumi, in "Ayumi and Aika," wants to get married to her boyfriend so naturally, she's shocked when he tells her that he wants to become a woman.

"Yukari and Mayuko" are both OLs. Mayuko's between boyfriends and bored, so she asks Yukari to pretend to be her girlfriend. It works out well, until Yukari realizes that her feelings for Mayuko are more than just pretend.

And finally, in "Miura-san and Me" Okabe loves Miura's beautiful hair. When Miura-san cuts it all off, Okabe learns to love her for herself.
