OVA
Description
Powawa is a supporting character in the anime Guardian Hearts, appearing in both the original series and its sequel, Guardian Hearts - Power UP!. She is a small yellow bird who can take on a human form, appearing as a girl who goes by the name Pō. Her original name was Tori, but the name Powawa was chosen through reader submissions. The series never fully reveals her true identity, leaving her origins deliberately mysterious.

Her background is closely tied to the protagonist, Kazuya Watari. Powawa is fused with the soul of Kazuya's stillborn twin sister, and this fusion is the reason Kazuya, despite being male, can transform into the Guardian Hearts, a power normally restricted to females. In this way, she is connected to his ability to become a heroic figure and plays an essential part in enabling his transformation.

In terms of personality, Powawa is notable for her genuine concern for the well-being of everyone around her. She is the only character who does not take sides, remaining neutral amid the romantic rivalries and frequent conflicts among the other girls living in Kazuya's household. Her caring and impartial nature makes her a calming presence in the story.

As for her role, Powawa serves as the narrator of the series, guiding the audience through events with an observer's perspective. She also uses her power to transform Kazuya into the Guardian Hearts when the situation calls for it, making her an enabler of the hero rather than a fighter herself. As a supporting character, her function is to watch over the main cast and help the story unfold, and she does not pursue personal goals of her own beyond ensuring everyone's safety and happiness.

Her key relationship is with Kazuya, to whom she is bound through the soul of his twin sister. This bond gives her a unique and intimate connection to him, one that is more fundamental than the romantic interest of the other characters, even though she never competes for his affection. Toward the other residents of the household, she acts as a neutral and benevolent figure who wishes only for harmony.

Her notable abilities include transforming between her bird and human forms and transforming Kazuya into the heroic Guardian Hearts. The full extent of her powers and the complete nature of her origins are not explained in detail, and the series leaves much about her ambiguous.

In terms of development, Powawa remains largely consistent throughout the story, maintaining her supportive, neutral, and caring role from beginning to end. She does not undergo a personal arc of her own; her significance lies in her bond with Kazuya, her role as narrator, and her status as the one character who cares for everyone equally.
