[Shukketsu Kansatsu Nikki (HemoglobinA1C)] 睡眠姦触手本 (Touhou Project) (SCANMTL)

Bound in a collar and heavy chains, Hecatia Lapislazuli sinks into uneasy sleep while glossy tentacles coil over her voluptuous body, turning the cover’s moonlit water motif into a dreamlike captivity scene. The monochrome interiors move from drowsy, vulnerable close-ups to increasingly intimate contact, with her flushed face, soft curves, and strained reactions carrying the tension beneath the recurring “Welcome” lettering on her clothing. A sparse closing page names the work 出血観察日記 and “TOHO Project FANBOOK FOR ADULT ONLY,” placing two tiny, cheerfully stacked Touhou mascots with cleaning tools beneath the publication credit.
