The world is at peace, but there are still everyday dangers. So, a new breed of protectors, known simply as "Heroes" have arrived on Earth.  Shy is Japan's new Hero, but is she ready to be a Hero? What does it MEAN to be a Hero anyway?
Just where did they come from, and how?
من أين أتو بالضبط، وكيف؟
Woher genau sie kamen, …
¿Cómo y de dónde salieron?
¿Cómo y de dónde salieron?
D’où venaient-ils ?
Et comment sont-ils apparus ?
Da dove sono arrivate? E perché?
Como, por que e de onde surgiram?
Как и откуда они взялись?
ส่วนเรื่องที่พวกมาจากไหนแล้วเพราะอะไร...
