Van, a lanky and indifferent swordsman, is on a quest to assassinate his fiancée's killer. The only distinguishing feature he has is that the killer has a claw for one arm, which is why he is known as The Claw Man. During his travels, Van comes across the city of Evergreen, which is defending itself against robbers attempting to plunder the city's coffers. Van encounters Wendy Garret, a shy young girl hunting for her stolen brother, in this metropolis. When the city requests Van's help in defending itself, he refuses, stating it has nothing to do with him, leaving the city to cope with the situation on its own.
