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.

al inframundo por primera vez.
Fue cuando entré
al inframundo por primera vez.
C’est à ce moment précis
Il momento in cui mossi il mio primo passo
in quel mondo oscuro.
Foi a primeira vez que eu coloquei
 o pé no lado obscuro do mundo.
