Tsurenai hodo Aokute Azatoi kurai ni Akai

Is this senior... female? Male? Neutral? Demonic? A transfer student suffering from an incurable disease called curiosity meets a mysterious being (human) who is beautiful, cute, cool, and terrifying. The first of a new generation of horror comic authors presents an abyssal love story, a ghost story to peek into and sensuality to you.
