"Felix!!"
"Welcome back!"
The moment Olivia and the rest saw Felix, they dashed towards him with feverish looks, scaring Felix into taking a step back.
"What's up with them?!" Felix wondered out loud a bit frightened by their overeagerness.
"It's because they saw all of your reckless fights from the windows." The driver smiled wryly, "Especially your wings."
The driver wasn't kidding, as everyone started barraging Felix with questions about the fights, but mainly about the Fuchsia Eagle Wings.
Before entering the bus, Felix completely removed them, thus even when he was asked to show them again, he couldn't do so.
Substances, just like potions were mostly temporarily and one time use. Even though the duration was still far from reaching 15 minutes, the moment Felix ordered for the wings to disappear, the grey substance on his back faded away, leaving his back itching like a colony of ants was crawling all over him.
