Hideshi Hino is a master of horror manga. When discussing Hino's works, the word "trauma" is almost always mentioned to the degree that "trauma" has become almost synonymous with Hino. The nightmarish stories, the extreme depictions of cruelty, the absurd and unhappy endings and the unique world of weirdness and black humor all come together in Hino's works. Countless children have been traumatized by Hino's works, and the trauma has never left them. However, while the shocking content and grotesque illustrations are repulsive, the "bizarre and lyrical" world of Hino's works, which depict the sorrows of the deformed, fascinates people both in Japan and abroad. Revisiting them as an adult, you will realize the true essence of Hino's world. In this book, occult researcher Hiroki Terai picks out five stories from among Hino's many works that are inevitably traumatic. In a conversation between Mr. Hino and Mr. Terai, valuable stories about their creation are revealed. The book also includes a complete version of "Underwater" with a problematic scene that was cut from the previously available version restored, a sequel to "Tomorrow's Hell" set in the year 2020, and a rare work whose existence is unknown even among devoted fans. We hope to bring you new discoveries and new traumas.
