Justice Akazuka (nickname Seigi) is a young man who is good at martial arts. Seigi rescues a homeless old man on the street one day from some thugs, and the man gives Seigi an object that imprints a tattoo on his palm. However, it is not an ordinary tattoo, but a special weapon that gives Seigi supernatural powers such as warping space-time. Seigi then meets a female American agent named Easy, whose duty is to recover the tattoos. Seigi decides to help her and gets wrapped up in a cross-national conspiracy.
