A hero must be compassionate, selfless and courageous.But that isn't all. Because a hero must also be powerful.In this world, power is everything. Strength decides who gets to save lives and who's left with community service.

Because humanity is worth fighting for.Even if I have to burn every villain alive to prove it.
