A pickup expedition heading to Odawara. Perhaps because they enjoy fresh fish every day, the girls around town strangely seem younger. Picking up a big-breasted gyaru who recently moved from Kansai, they get her into the car and start stripping off her sexy clothes one by one while engaging in erotic negotiations. Lately, targeting "history-loving girls" has become more common, and on the way to Odawara Castle, they coincidentally encounter a perfect solo-traveling female college student. At this point, deciding it's fine even if she's not a local girl, they approach her.
