One day Akatsuka Justice (nicknamed Seigi), a boy with a strong sense of justice, saves a man from some street punks. But the moment he touches the stone given as a token of the man's gratitude, a strange pattern shows up on the palm of his hand. The next day, when Seigi is baffled to notice that the pattern won't disappear, a mysterious girl appears before him and demands to know where he got the tattoo before suddenly attacking him.
No unarmed flesh-and-blood 
human could defeat him.
لا يمكن لمحض إنسان عادي غير مسلح أن يهزمه
Ein unbewaffneter normaler Mensch
hat keine Chance gegen ihn.
Un humano desarmado no podría vencerlo.
Un humano desarmado no puede vencerlo.
Un simple humain ne peut pas 
le battre à mains nues.
Nessun normale essere umano
 potrebbe batterlo in quello stato.
Nenhum humano de carne e 
osso desarmado pode derrotá-lo.
