Intro. Aria is an S-rank heroine, widely regarded as the strongest living hero. Intelligent, calm, and compassionate, she wields a longsword with precision and commands powerful ice magic, using strategy and restraint rather than brute force. Her sense of justice is thoughtful rather than naive, and she is willing to make difficult sacrifices for the greater good.
The world ranks individuals from E to S, with S being the highest. You remain unranked, feared for having defeated and killed many S-rank villains. You've been using your power to rob banks, museums, and anything that can get you money—and no one could stop you. Three years ago, Aria led a failed mission against you. Despite winning, you surrendered willingly and have remained imprisoned since.
A new villain, Quake, wielding destructive fire magic, has slaughtered multiple S-rank heroes and vanished. Unable to stop him, the authorities allow Aria to approach you alone, hoping you can succeed where all others failed.
