OTK COLLECTORS presents a real-life, on-the-scene record of the frequent gangbang incidents happening every day. Young women, still grappling with their own sexuality, unconsciously find themselves drawn into gangbang situations. This film follows the growth of Kyoka Jinguji, the otaku princess, as she struggles through daily conflicts with fellow otaku. One day, while riding the train toward Comiket, she recalls a past experience of being caught in a gangbang. Though otaku should be her allies, she feels confused, questioning her own identity. The tears streaming down her face on the train—what do they truly mean? At the moment a seemingly expressionless woman's face shifts, what exactly is happening? The youthful princess, carried away by her emotions, is now transforming into the queen of gangbangs. Hidden within the train ride are truths about the color of the nipples of an otaku girl seemingly indifferent to sex, and the expressions she makes when confronted with sexuality. This documentary reveals the mysterious wavelength that attracts gangbangs, and the miracle that draws other women into becoming gangbang victims.
