Nero, also known as Secre Swallowtail, is actually a 500-year-old human who was transformed into an anti-bird by forbidden magic.
Secre used to serve Lemiel Silvamillion Clover and got cursed into Nero's bird form, but she鈥檚 still super helpful and wise!
Honestly, Nero just adds layers of cool mystery to the show. She went from bird to waifu with secrets.
