Description:

Wolfsmund is a dark historical manga set in the early 14th century of Europe (Switzerland). The story revolves around the eponymous fortress in the St. Gotthard Pass which is ruled by a sadistic tyrant. Each chapter deals with characters who for some reason have to cross the pass and who end up getting interrogated by the tyrant. What sets this manga apart is the fact that there's rarely a happy ending for our protagonists. The author pulls no punches to show us just how brutal and inhuman the Middle Ages really were.

Description:

This is the story of a terrible crime committed against a 17-old-girl, committed, in part, by 17-year-old boys. Why did such a thing happen? Why was no one able to prevent it? In the beginning, high school boys Hiroki and his friend Takashi are rescued from bullying by a notorious gangster, Miyamoto. At first, they are thrilled to be under his protection, and cheerfully run off anyone who threatens them with the mere mention of Miyamoto's name. Soon, they learn that there is a lot more to being in Miyamoto's gang than just being protected. In return, they're expected to offer loyalty and obedience, or face possibly deadly consequences. This becomes harder as the violence and the crimes they find themselves committing begins to escalate. One night, they kidnap a high school girl, Sachiko. Now Hiroki has two battles to face. Internally, he faces the dissonance between his sense of self-preservation and his conscience. Externally, Sachiko's twin sister Miki, who goes to Hiroki's high school, her parents and the police are searching for the missing girl. Will Sachiko ever return home? What kind of person--or monster--will Hiroki become? (Source: MangaHelpers)

Description:

The basic plot is that an orphan girl named Midori is taken in (read: enslaved) by a traveling freak show. The freak show includes such unsavory characters as a mummyman, a snake woman, and a drooling man with no limbs. The owner of the freak show, the eponymous Mr. Arashi, is a strict man who allows his freaks very little freedom or joy in life. He is especially cruel to Midori, our heroine. Midori works, not as a freak since she is normal, but as a sort of caretaker of the freaks. (Source: everything2)

Description:

A rather morbid, sombre manga about two high school students, Kamiyama Itsuki and Morino Yoru, who have a peculiar interest in deaths and especially in murders that are committed near to them. Due to their strong fascination with murder and highly-developed analytical skills(along with some luck), they manage to solve the murders that have even eluded the authorities. However, acting on their own sense of justice and in self-interest, the murderers are often able to escape with the murders that they have committed. Often, it is Kamiyama that solves the cases even to the most subtle of details, but he is only interested in one thing, and that is the method to which Yoru Morino should be killed.
