This year, two works were produced for Dogma as part of the Kokoha's story series: "M Certification Exam" and "House of Lustful Insects." This time, the theme centers on Kokoha's long-awaited challenge—her first experience with bondage SM. Director KIM was particularly impressed by how Kokoha deeply immersed herself in the role in "House of Lustful Insects," relating strongly to the character's background. Though she usually struggles with such roles, her ability to naturally express emotions during dramatic scenes was highly praised. However, there was concern that Kokoha might become too nervous to move when actually experiencing real bondage with a professional rigger. To address this, the production crafted a twisted incestuous sibling storyline. The older brother left home three years ago after a fight with their mother. His younger sister, Kokoha, has been waiting for him ever since. The brother knows that shortly after middle school, Kokoha stopped attending classes, became unable to talk to people, and began self-harming. By chance, he came across an article in an SM magazine's amateur submission section, describing how a reclusive girl who used to self-harm found emotional healing and became cheerful through rope bondage. Inspired, he decided he wanted to help heal Kokoha. He traveled to Tokyo, became an apprentice under a top-tier master rigger, and after three years of rigorous training, mastered the art of shibari. Now, he returns home after three years. The drama unfolds based on this backstory. After completing outdoor filming, the shoot moved to the studio, where rigger Haru Amata made his appearance. During a break, Kokoha and Haru began talking, and it was suggested that Haru briefly examine Kokoha's physical condition and conduct a light practice session—temporarily halting the drama shoot to ease her into the experience. Initially tense, Kokoha gradually brightened as Haru's ropes wrapped around her, successfully completing challenging positions like the M-shaped suspension. After a 30-minute bondage session, once released from the ropes, Kokoha couldn't stop smiling, overwhelmed with joy and fulfillment from finally experiencing the rope world she'd always dreamed of. Returning to the drama shoot, she powerfully delivered the emotionally intense scenes with her brother. Later, she requested another session from Haru, enduring further challenges: reverse shell suspension, flogging with a rose-tipped whip, and candle play that brought her to tears. This release, "Imouto M Shoujo," blends dramatic narrative with documentary-style realism, centered on the brother-sister relationship and Kokoha's first full bondage experience. If Kokoha continues to enjoy SM and undergo further training, she holds great potential to become an outstanding SM actress. Truly, it's heartwarming to see her deepest wish finally come true.
