Minato Yoshii longs for a normal life, but she has a secret: she's actually the daughter of a yakuza family. Desperate to find a new job, she goes to an interview; however, she gets turned around and accidentally barges straight into the office of the Akaiwa Gang, her family's biggest rival. The gang members there burn some strange incense and get ready to pounce on her, but she's saved at the last minute by none other than Renya, the underboss of the gang himself. And even though they've only just met, he hits on her and asks her to be his woman…! Minato, never having been in a relationship before, has no idea how to deal with Renya's advances… And not only that… she's starting to feel extremely strange inside due to the incense from earlier, which was an aphrodisiac. Renya is forced to save Minato from the aching desire she's experiencing, and she suddenly finds herself in uncontrollable pleasure she's never known before!
