The main character of this particular tale! She's the daughter of a rich industrialist and never seen without her headphones. She thinks she makes quite the hero, but reality is a bit different from her expectations.
Blitz is Steffi's alternate identity as a vigilante. She usually rides around in her kiwi bird mech, but recently she also obtained powered body armor. People have guessed her true identity by this point, partially thanks to her ridiculous hair.

I imagine her with a Higher pitched voice and a slight German accent (you may occasionally have to read German lines)
