Undies, Go!. Neo Tokyo is undergoing a series of jewelry thefts. Meanwhile, Rio is in need of money to pay her debts, but Team Warrior is assigned to a low paying job tracking down a women's underwear thief. However Rio, the thief and leg fetishist Yuji stumble upon clues to the mastermind behind the jewelry thefts after they encounter the cross-dressing Chimama gang in a bar. Although Rio and Team Warrior crack the case, the costs she incurred in the process wiped out any possible bonus, so Rio still has to get a part-time job to pay her debts.
