Lupin and his friends are targeted by the all-female terrorist group "Bloody Angels". They are after the "original metal" – a mysterious object Lupin stole from Area 51. Lupin's weakness for women is certainly not going to be any help this time. Neither is Goemon, unless he can find a way to mend the damage made by his overconfidence in his sword. The major question is whether this is just a series of professional assassination attempts or if the Angels have an underlying agenda...or a personal grudge.
