"Pft."
In truth, even an hour before Riley stepped inside the Hero Association tower, Aerith was already seated inside the lobby. And as soon as Riley entered, she covered her face with a tablet so that people wouldn't notice the growing smile on her face.
Most people generally do not know what she looked like– and so, just a cap and sunglasses, and she was like everyone else. Riley, however, was completely different as an albino– they were even rarer than supers.
And so, Aerith came up with a plan; officially register Riley as a superhero.
In that way, even if he wore a mask outside 24 hours a day, 7 days a week, no one would even bat an eye. They could have gone with an entire helmet that covered his entire head, but exposing his long black hair would be better– the farther he was from looking like Darkday, the better.
It was the best plan that Aerith came up with, 2nd was not allowing Riley to go outside.
