Edelweiss
Licensed by MangaGamer
Summary
Four young high school students--Kazushi, Appo, Pierre and Daigo--grow sick of their less-than-average, sensually-depraved youth. With nothing but poor grades to show for their transient existence, the band of buffoons seek to spice up their lives. Once word of an exchange student program to an all-girls school reaches Kazushi's ears, he and his friends set out to improve their grades. Eventually, their hard work pays off, and they find themselves on a boat to Eiden Island, which is home to Eiden Academy, their new school.
However, upon arriving, the boys learn of a secret that causes them to question the intelligence of their decision to jump at this "opportunity": the school deals in the dark arts of alchemy, and endeavors to teach its students its various facets. Kazushi and his friends quickly find themselves biting off more female drama than they can chew.
