Description:

Hachiman Hikigaya, a student in Soubu High School, is a cynical loner due to his traumatic past experiences in his social life. This eventually led to him developing a set of "dead fish eyes" and a twisted personality similar to that of a petty criminal. Believing that the concept of youth is a lie made up by youngsters who face their failures in denial, he turns in an essay that criticizes this exact mentality of youths. Irritated by the submission, his homeroom teacher, Shizuka Hiratsuka forces him to join the Volunteer Service Club—a club that assists students to solve their problems in life, hoping that helping other people would change his personality. However, Yukino Yukinoshita, the most beautiful girl in school, is surprisingly the sole member of the club and a loner, albeit colder and smarter than Hikigaya. Their club soon expands when Yui Yuigahama joins them after being helped with her plight, and they begin to accept more requests. With his status quo as a recluse, Hikigaya attempts to solve problems in his own way, but his methods may prove to be a double-edged sword.

It’s the vacation of a lifetime, a trip to a remote island filled with geniuses–and murder. On Wet Crow’s Feather Island, a tiny speck in the Sea of Japan, lives Akagami Iria, the exiled daughter of a powerful family. Born into great wealth, she was a princess of the highest pedigree–until she was cut off by the leader of the Akagami Foundation. For the last five years, she’s lived on Feather Island with her maids. But she hasn’t been alone. She has invited the best minds Japan has to offer to come and stay with her. And so nineteen-year-old college student Ii-chan and his best friend, computer genius Kunagisa Tomo, find themselves as Iria’s guests at her elaborate mansion. Surrounded by fascinating women–a chef, a fortune-teller, a scholar, and an artist, not to mention his own friend Tomo–Ii-chan is feeling a little overmatched intellectually. But the sudden discovery of a grisly murder sends the island into shock. And Ii-chan discovers that he does possess a bit of genius: the ability to discover what is real and what is fake . . . who is who they claim to be–and who is a killer. (Source: Del Rey)
