A woman enters a neurology counseling room. She is Aya Shiomi, an actress in her fourth year as an exclusive performer for Dogma. The doctor reviews her CT scans and EEG results, confirming her brain function is completely normal. Yet, she claims to see gears inside her head. She first saw them when she was in third grade, after crashing into a utility pole while riding a pink bicycle her parents had gifted her. The handlebars pierced her abdomen, causing intense pain and difficulty breathing—yet in that moment, she saw gears in her mind. Her consciousness went blank, overcome by a euphoric sensation that surged through her entire body. It was her first true ecstasy. Since then, she began recounting to the doctor a series of intense experiences blending pain, pleasure, and fantasy: eye torture, sex that feels like her skin is being peeled from her body, being hung upside down with her ankles bound and spread, lashed with a single whip, and hardcore deep throat sessions drenched in masses of salmon roe. The doctor becomes entranced by her world, journeying through the surreal landscape of her mind. This work, "Gear: Koshiwa," is based on Aya Shiomi's childhood memories, portraying a bizarre and dreamlike realm. Due to an atypical neural structure, her brain uniquely intertwines pain and pleasure. Step into the extraordinary world of "Gear: Koshiwa" and experience her singular reality.
