When a train bound for Oslo disappears, then reappears and crashes 3km from its tracks, Botan Negoro, a high-school girl trained by her ninja grandfather to save the world, is called in to recover the crystal fragment said to have caused the accident.
I mean, you raised me to be
a ninja to "save the world,"
أقصد، ربيتني لأصبح 
،"نينجا "تنقذ العالم
Ich wurde halt als Ninja erzogen,
um die Welt zu retten und so,
Me educaste para ser una ninja
y "salvar al mundo",
Je commençais à craindre

एक निन्जा की तरह पाला,
Você me criou para ser a ninja
que vai "salvar o mundo",
