After receiving a note from Lupin, Zenigata arrives at the birthday party of a rich politician. Sure enough he sees Lupin, who tells him the note is a fake and he’s there to find out who sent it. However, mayhem ensues when a gang of masked assassins known as Tarantula gatecrash the party, killing all in sight! During the commotion, Zenigata is shot by a man wielding a Walther P-38; a gun that Lupin recognises all too well. Then, when Lupin sneaks onto the uncharted island that serves as Tarantula's base, not only is he forcibly recruited into the group, but he also gets caught up in a deeper plot that splits the assassins in two. Can Lupin settle the score from his past, and maybe snag some gold along the way?
Bolt Crank is a mercenary. Rather than selling his services to whoever can pay, he accepts jobs for his own reasons, and insists on doing things his way. This isn't the only thing that makes Bolt different, for he also has an appetite for eating metal, and can actually reform things he has eaten into the palm of his hand! Follow Bolt's journey and watch while he takes on jobs, makes some money, and saves beautiful women in need.
If you enjoyed the action aspect of Lupin III: Island of Assassins, then you may want to chek out Eat-man. Both anime have a reasonable amount of action in them and a similar sort of art style. If you liked one, then try the other.
