A set of Auspicious Armor appeared in PT16 in Yūto's home. It was passed down in Yūto's family for generations, with a legend saying it was related to Charcadet. After hearing it, Yūto's Charcadet felt compelled to touch the armor and evolved into Armarouge as a result.
A set of Auspicious Armor appeared in a flashback in PASV09, where it was given to Scarlet by Mela, along with a Charcadet. She later used it to evolve Charcadet into Armarouge.
