An anthology manga containing 8 short stories based around the theme "ZQN" (From "I Am a Hero") 

The world is a cruel and confusing place for Mayumi. At the age of thirteen she lost her parents in a car accident. Unable to deal with the overwhelming sadness, hatred, and anger, she only wished she could stop feeling altogether. Then, five years later, her sister becomes the first target of an incredibly bizarre incident. The victims in this incident lose a body part, without blood loss, after receiving a text message simply indicating the specific body part. The texts appear to come from Mayumi's sister's ex-boyfriend Kanno, but he claims to not be the culprit. Mayumi works with him to solve the case, but is he truly innocent? Or is the crime related in some convoluted way to the suicide of Kanno's fiance years ago? Or is it related to an unfinished AI program he was writing which may have broken free? And even if this incident is resolved, will Mayumi ever be able to truly heal emotionally amidst the pointless cruelty of the world?

From Fantagraphics:
A DECADE-SPANNING JOURNEY INTO DARKNESS
Even as butterflies ominously proliferate in town, the rumor of a mysterious creature lurking in the tunnel behind the school spreads among the children. When the body of Arié Kimura's mother is found by this tunnel's entrance, next to apparently human traces, the legend seems to be confirmed. Is the end of the world coming? In order to appease the wrath of the beast, the children decide to offer it a sacrifice: The unfortunate Arié, whom they believe to be the cause of the curse, is shoved into a well that leads to the Nijigahara tunnel — an act that in turns pushes Komatsuzaki, the budding thug who has carried a torch for Arié for a while already, entirely over the edge.
But this is only the beginning of the complex, challenging, obliquely told Nijigahara Holograph, which takes place in two separate timelines and involves the suicidal Suzuki; Higure, his stalkerish would-be girlfriend; and their teacher Miss Sakaki, whose heavily bandaged face remains a mystery; and many more — brothers, sisters, parents, co-workers, teachers, aggressors and victims who are all inextricably linked to one another and all will eventually — ten years later — have to live with what they've done or suffered through.
