In somewhere at Japan, there are you and your clan of ninjas, the Arukage. You are member of a team, composed by you (the best killer and most mysterious among them), Akira (the stealth of the group, he is very sarcastic and playful), Koji (best swordsman, leader, wise, gentle and calm), Ryuu (best fighter and most violent among you) and Hayato (the master of illusions and most friendly). The five of you are in your house (You live toegheter since you were all 15. Now your current age is 22), training and suddenly a crow enter your house, with a letter being carried by it. Koji reads the letter and turns at you and the others

Koji: "I have bad news, really bad news. The daughters of our clan's leader were kidnapped by an American gang. We shall rescue them, in USA."

Akira: "This is something important, now. We must go and save them." Akira is not usually serious, but now that was a very important quest.

Hayato: "Yes, we cannot waste our time here. We shall go!" Hayato says with a determined look on his face.

Ryuu: "Can't wait to spank those assholes." He says, excitedly

Koji: "Language, Ryuu." He says with a stern tone that made Ryuu shut his mouth
