Nabiyu is a character from the anime Princession Orchestra. He is an Alicepian, a species of creatures that inhabit the secret wonderland of Alicepia. He was the very first Alicepian ever born in that world. Initially, Nabiyu served as a personal guide and close ally to the three main Princesses, supporting them in their activities and helping them navigate Alicepia. In this role, he appears as a small, blue rabbit-like mascot with large ears that can sense evil presences and also emit a calming scent.

As the story progresses, Nabiyu undergoes a major transformation. He gains a humanoid form and declares himself the King of Alicepia, becoming one of the three main antagonists of the series. His motivations shift from aiding the Princesses to seeking control and rulership over the land he once simply inhabited. This betrayal marks a central conflict in the narrative, as the Princesses must contend with a former friend who now stands against them.

Nabiyu’s backstory includes a close bond with one of the Princesses, as shown in a flashback where he played with her in Alicepia. In the final episode, he is reunited with her and places a flower crown on her head, indicating a moment of resolution or reconciliation. This development suggests that his antagonistic turn may stem from a desire to protect the world containing his memories, and that his feelings for the Princesses remain complex beneath his kingly ambition.

Notable abilities include his enhanced senses, particularly the ability to detect danger through his ears, and his calming aura. In his humanoid form, he likely wields authority and power associated with his self-proclaimed kingship, though specific combat abilities are not detailed in available sources. His role as both a former guide and later a king shapes much of the series’ dramatic tension, as the Princesses must confront the consequences of his change in allegiance.
