+## What's in the name?
+
+The project name is inspired by an [anti-bird](https://blackclover.fandom.com/wiki/Anti-bird) in an anime called [Black Clover](https://blackclover.fandom.com/wiki/Black_Clover_Wiki). The anti-bird, which the [Black Bulls](https://blackclover.fandom.com/wiki/Black_Bull) squad calls _Nero_ is apparently a human named [Secre Swallowtail](https://blackclover.fandom.com/wiki/Secre_Swallowtail). It's a really cool anime with lots of magic!
