Piisuke, a phoenix chick, first crosses paths with Chacha as she clashes with Yordas, a servant of Daimaō. Shielded by Chacha from danger, he forges an unbreakable bond with her. When adversaries threaten their safety, Chacha’s Magical Princess form activates the "Winged Feather Skill Up!" ability, triggering Piisuke’s metamorphosis into the Phoenix Sword—a radiant short blade adorned with pink plumage and a gleaming central gemstone. This weapon proves pivotal in clashes against foes such as Access, Daimaō, and the demonic duo Baritone and Soprano, empowering Chacha to unleash the "Sword of the Phoenix Flash" technique.

Summoned by an arrow loosed skyward from Chacha’s Magical Bow, the Phoenix Sword replaces her outmatched Beauty Serene Arrow, its strength rooted in the united resolve of Chacha, Riiya, and Shiine. Piisuke’s existence as a guardian entity intertwines with their collective struggle, channeling their combined magic into the blade’s potency.

During the crisis sparked by Soprano’s shattering of the Holy Bird’s seal, the trio sacrifices their Princess Medallion, Bracelet, and Ring to mend the Gates of Hell. This act severs Piisuke’s link to the sword, permanently reverting him to his phoenix chick form. Though he stays by their side afterward, his combat role ends.

In subsequent events, Piisuke recedes from the narrative forefront as Chacha wields new artifacts like the Crescent Aurora Bracelet. Yet his earlier actions remain instrumental in dismantling Daimaō’s threats and securing the kingdom’s resurgence, cementing his legacy within the saga’s core conflicts.
