Yotsuya, Simone

Fin de Siècle Detective Club is dedicated to the very gay and very passionate love of Sherlock Holmes and Doctor Watson. I suppose that it could even be called a doujinshi, since it's blatantly based on Conan Doyle's work, and many of his characters make appearances throughout the story. In fact, the main story is split into three stories -- each one focusing on a different aspect of the Holmes/Watson relationship.

Complex

コンプレックス

Shimizu, Yuki

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".

Half-Japanese Randy "Ryo" Maclean is assigned as a new detective to the 27th precinct at the New York City Police Department. His boss pairs him with Dee Laytner, a good-looking veteran prone to impulsiveness. Much to Ryo's confusion, Dee takes an immediate interest in his new partner.

In their first case together, Ryo and Dee must take care of Bikky—a young boy whose father was killed due to his involvement in a shady drug trafficking business. Bikky denies having any knowledge about his father's actions prior to his murder. Even so, it is up to Ryo and Dee to protect the boy from those wanting to get rid of him and preserve any evidence he might be holding back.

As time goes on and the detective duo works increasingly more together, the distance between them gradually shortens. But could Ryo ever reciprocate Dee's feelings?

Fujimoto Hiroya is at the top of his class. He's the Student Council Vice-President, spends all his time studying and is the idol of all the "good girls".  But the truth is, he'd trade it all just for the chance to be someone else... someone popular, outgoing and carefree... Someone like Masaki.

Masaki's what Fujimoto's friends would call an "idiot".  He'd rather play soccer than study, almost never cracks a book, and is popular with all the "normal" kids.  He's got flashy clothes, bleached hair and a reputation just a lousy as Fujimoto's is good.

In the summer of Fujimoto's freshman year of high school, he resolves to change his image and his life... all to make friends with Masaki.  But can dyed hair, new clothes and a piercing really change a person inside? 

Classic BL by the "dream-team" of novelist Koh Akizuki and mangaka Meiko Koide. 

Please note that this title deals very frankly with some rather "heavy" issues including, but not limited to homophobia, gay bashing, coming out, HIV/AIDS, promiscuous sex, rape, and suicide.
