The Radiant Petal (Japanese: かがやくはなびら Shining Petal) is a Key Item introduced in Generation VIII.
The Radiant Petal is used along with a tuft of White Mane Hair or Black Mane Hair to create the Reins of Unity.
The Radiant Petal appeared in PASS39, where it was created by Calyrex, at the cost of causing it to pass out for a while. The petal and the Black Mane Hair obtained by Bede were later combined by Henry to create the Reins of Unity.
