Haruka and Mamoru take to the streets, fleeing the deadly invisible
enemy that pursues them. With Mamoru wounded and his sword blunted,
Haruka fears that prolonging this fight will only end with her
protector's destruction. But Mamoru has not been relying on his strength
alone. Igawa has been working behind the scenes to counter the
assassin's drones...but is the pair's technical expert up to the task of
disabling government-grade weaponry? Or has Igawa met his match in the
world-class hit man, Fang?!
