Kenji is just an ordinary college student. One day he was ordered by his Senpai, and was asked to retrieve Senpai's personal belongings, which happened to be a bag of sex toys. On the way he met Mana-chan (a girl he liked), who after finding out what he was carrying a bunch of sex toys, and bounced out. Wanting to explain the misunderstanding, Kenji chased after her, but gets plowed by JAV Truck-Senpai after he stops to bend down and pick up the dildo he dropped. Being the standard Isekai trash we all love to hate, once he died he wakes up on another world in a strange forest with only the clothes on his back, the vibrator wand in his hand, and all virginities intact.
