Yoshida Akimi manga
From ShoujoMagic: Arisue Sei lived as happily as any normal kid would, just him and his mother -- a particularly private woman -- on an outlying island of Okinawa. There were also his friends Toichi and Moichi. The only unusual things about Sei were his sharp instincts and high intelligence. But everything changed when his mother was killed and he was kidnapped by the people of Neo Genesis. Now, six years after the kidnapping, Arisue Sei has returned to Japan with the title of "Doctor" at only the age of 18, and he's not the Sei that his friends remember. There are bodyguards with him who protect him from others who wish to possess his superb intellect. He says he's come back to assist with the research at Rakuhoku University, where Moichi now works, but here is where the door to Sei's secrets just begins to open...

Sayoko is a newly transferred student: gifted with rare beauty and mysterious and magnetic charm, she captures every student's attention. Among them, the introverted Yuiko and the grumpy Mari become friends with Sayoko, while Ryou, a known womanizer, wastes no time and tries to hit on her, unleashing his girlfriend's rage. But this story has countless plot twists, characters and secrets… From Banana Fish and Yasha's author, a manga that won a Shogakukan Award and defined as "a must" by Matt Thorn, one of the greatest shoujo manga experts.

Toshi is your regular senior high student, except in the evenings when he's a bartender at a joint frequented by American servicemen, where he deals drugs, pimps, and even cross-dresses a little on the side. And his best friend Miyuki just happens to be the son of a loan shark with gay tendencies. If this sounds like the hardboiled world of Yoshida's later and most well-known work Banana Fish, it's balanced by Toshi's madcap adventures at his all-male school (where his mates jerk off to everything in sight, and scenes from shoujo manga are performed in all their histrionic glory), as well as the unexpected delicacy of his relationships with the women in his life. This episodic drama is bursting with all the frustration, the tenderness, the audacity, the horniness and the hilarity that comes with being young and male. All the tough, silly, dirty, and sweet things boys get up to in the locker room and out of it never brought a bigger smile to your face. Bunko ver released in 1994. summary from Baka-Updates Manga

If you don't want to cry, don't start reading it!]**
