Yuu Watase's Masterpiece Collection Volume 5 consists of four stories.

1) Mint de Kiss Me -
There is a legend that if you kiss the man you like with a mint candy in your mouth, you can become one with your love. Misono is a rather superstitious girl who decides to test this out on Tohno-sensei, a young teacher she has a crush on. Unfortunately for her, she makes a mistake in the attempt to surprise him and instead kisses her fellow classmate Shindou. Of course this would be the time for the legend to work quite literally as Misono’s spirit enters Shindou’s body.

2) Genseika -
Chiya goes to school with her friends and witnesses one of them die suddenly as a flower bursts out of him. The three friends had been together since elementary school, the death hitting Chiya and Yutaka hard. When other people begin dying from the flowers, they investigate possible reasons for such usual deaths. To her surprise, she finds answers close to home.

3) Furimuke Romance! -
The hero of girls targeted by guys peeking into the locker room, Taka has quite the violent tomboy reputation. But all she wants is for some handsome guy to ask her out. A cheerful street vender, Ryouta gives her a special ring with a heart locket pendent to hold pictures. When two photos are enclosed, romance is in the air.

4) Hang in there Nakago (Part I) -
Involves the scenario where Fushigi Yuugi was actually done by real actors. Unfortunately, Nakago (stage name) is a lot more unconfident than the character he plays. At least his one main fan, an unnamed woman with flowers, is there to support him through his worries.

Takiko Okuda is a strong-willed girl living in the Taisho Era. She needs to be strong -- Oosugi, the one man she's ever loved, is a married man; her mother is terminally ill; and her father, Einosuke, has not been home in over a year. When at last Einosuke returns, it's with a notebook full of Chinese scribblings that seem more important to him than the death of his wife. Furious, Takiko steals away his completed translation -- "The Universe of the Four Gods" -- with the intention of tearing it to shreds, but the instant she opens it, she's surrounded by light... And it is said that this is how the legend of the Priestess of Genbu began.
