Utahime Fight is a collection of three short stories, all of which are about magical, mysteriously attractive girls and they effect they have on the people around them. 

In the first story, a girl and her two friends (one male, one female) are really magical fighters for something - probably love and justice. 

The second story follows two girls who are magically drawn into the plot of a movie, in which a prince strives to save his mother and his land. After being threatened with their lives, they wake up in the library in school. They have a final scene in which they admit that they love each other and story ends.  

The third story is about a magical creature that enchants a young man and brings love into his life. (description from http://okazu.blogspot.com/2005/03/obscure-yuri-manga_23.html)

Mistaken identities, bizarre accidents and pratfalls, tragic pasts and plenty of broken hearts, and that is just for starters! Love Mode tells the story of the lives of the men involved with the classy male escort service, Blue Boy. Love lines intertwine and cross, friendships are made and broken in this boy's love classic!

Sakashita Izumi, your typical straight high school student, gets into a sticky situation with a gay translator, Takamiya Katsura, when he gets mistaken for Izumi - an escort from B&amp;B (Blue Boy)! The two go on a date, Takamiya goes all the way with the young Izumi, and now the older man's in love with him. Tiny Problem: Izumi is slightly homophobe. Will he eventually convert in that which he fears?

Reiji, owner of B&amp;B and other sleazy clubs (and seemingly not gay) finds out his girlfriend had been cheating on him - just after dumping her. He bumps into a young, family-less, money-less, trustless high school named Naoya who at that moment gets knocked out by a pot that Reiji's vengeful ex-lover drops on his head. Reiji accompanies the young boy, feeling bad that this is partly his doing, only to find that now Naoya is homeless since his apartment burned down and finally ends up taking in this "stray cat".
