A delivery health enthusiast travels to the ninja town of Koka in Shiga Prefecture to learn ninjutsu, boosting his excitement in pursuit of real sexual encounters. Set in the historic ninja homeland of Shiga, this special experience blends eroticism with ninja elements. Delivery health man Ishihara Kenbo transforms into a full-fledged ninja, deepening his interactions with escort girls. First is "Mizuki," whose charming smile and talkative nature create a lover-like atmosphere, offering skilled oral techniques so intense you can judge the pleasure by the ejaculation distance. Second is "Rin," with a perky, uplifted ass and a gaze that's both gentle and powerfully intense. Kenbo incurs her wrath, placing him in a dire situation—could her true identity be a seductive kunoichi who drains men of their strength? An intense series of real sex encounters with these delivery health girls awaits.
