With a nasty attitude and something rotten in his soul, high school student Yu Seongbin has picked the weak Han Gyuhwan as his victim. As no one cares enough to put a stop to the violence Gyuhwan suffers, his mind festers with fantasies of standing up to his bully and the useless adults around him, picturing himself pulling out a shotgun to exterminate them all.

When their class leaves for a trip, it quickly spirals into a living nightmare for Gyuhwan. Seongbin inevitably starts harassing him, but Gyuhwan finally finds the courage to resist him. However, his bravery is short-lived, and he escapes into the woods, with an enraged Seongbin close behind him. But after he falls off a cliff, Gyuhwan stumbles upon a strange shotgun and a box of 30 bullets that he, in his desperation and exhaustion, intends for his classmates and apathetic teacher.

Back at the camp, the class' talent show turns sinister. Something unnatural creeps in from the shadows, and as people begin transforming into twisted, bloodthirsty monsters, it seems that only Gyuhwan's mysterious shotgun can truly finish them off.

Shotgun Boy

엽총소년

Lovecraft, H. P.

Tanabe, Gou

What links together two bands of worshippers, one deep in the Arctic snows, one hidden in the bayous of Louisiana, is more than their shared practice of blood sacrifice.

It is the inhuman phrase they both chant: Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn—"In his house at R'lyeh dead Cthulhu waits dreaming." Now these nightmares will disturb the sanity of Francis Thurston, a young man pursuing an investigation into the cult of Cthulhu that leads to the most forsaken spot in the vast Pacific...and to Earth's supreme terror, the risen corpse-city of R'lyeh.

First published in 1928, The Call of Cthulhu, rendered in chilling detail by modern manga horror master Gou Tanabe, is the most famous of all of H.P. Lovecraft's stories, and was the namesake of the acclaimed role-playing game system set within the Cthulhu Mythos.

For a long time, Rika Furude never considered a life outside of the mountain village of Hinamizawa; spending every day with her friends seemed like it would be the best outcome she could ever hope for. However, a desire begins to stir in Rika's heart—one that she also wants her best friend, Satoko Houjou, to realize with her. Rika wishes to go to St. Lucia Academy, a prestigious school for well-to-do young ladies, something that is in direct contrast to the crying cicadas and rural nature of Hinamizawa. Satoko is hesitant, as she has never cared about studying, but after years of practice exams, both girls start their new lives at St. Lucia.

Rika's poise and graceful demeanor helps her fit in immediately at the new school, while Satoko struggles immensely. However, she was never really interested in adjusting—as long as she had Rika by her side. But when Rika befriends a group of refined young ladies, Satoko begins to feel isolated. Soon, her grades start to suffer, and the gap between the two friends continually widens until Satoko is at her breaking point. Left in a pit of despair, Satoko's desperation soon turns into something much darker, leading her to do the unthinkable.

Keiichi Maebara has not lived in the rural village of Hinamizawa for long, but he has already made a group of close friends. His companions—consisting of Satoko Houjou, Rika Furude, Mion Sonozaki, and Rena Ryuuguu—all welcome Keiichi with open arms into their after-school club, where each day is filled with a flurry of games and penalties. However, happy faces can sometimes hide the most pain, and seemingly innocent actions can mask damning truths.

Strangely enough, these events have all happened before. As one individual observes these bizarre phenomena, they take steps to change the imminent tragedy that they know is coming. With the yearly Cotton Drifting Festival quickly approaching, it becomes clear that someone close to them is orchestrating the impending doom.
