AX-3 is an assassin with the equal gun skills of Golgo 13. He was given the assignment to take out a CIA papain facility using toxic weapons, with a client different from Togo. AX-3 first interrogates the proprietor of the factory and learns it is on an island. The blonde assassin meets up with Togo and they take on the factory together. After killing the factory staff and blowing up the equipment, poisonous animals begin to escape. Just then, AX-3 then receives orders to eliminate Golgo and they have a duel. When their guns run out, Golgo takes a knife and throws it fatally at AX-3. Before dying, AX admits the two were equals with guns.
