Haru is a young boy who appears in the music video Living in a World Without Magic. He is first encountered on a rainy night, lost and alone, on the brink of death. In this vulnerable state, he is taken in by Sara, a mysterious one-eyed witch who lives on an island floating high above a town. Sara welcomes Haru with warmth and kindness, offering him a hot meal and a place to stay. Over time, the silence between them gives way to a growing sense of comfort and connection.

Haru's personality is shaped by his initial solitude and fragility. He is quiet and withdrawn at first, but as he experiences Sara's care, he begins to open up. His motivations are not explicitly stated, but his journey suggests a deep need for safety, belonging, and human warmth. His role in the story is that of a lost soul who finds refuge and transformation through another person's compassion. The central relationship in his life is with Sara, whose gentle presence becomes a turning point for him.

The story also reveals that Haru's life is reset by an hourglass spell, adding a layer of mystery to his existence and suggesting that his meeting with Sara may be part of a larger, perhaps cyclical, fate. Through his time with Sara, Haru undergoes a quiet but profound development, moving from isolation toward trust and emotional connection. As for notable abilities, no specific powers or skills are attributed to him; his significance lies in his emotional arc and the bond he forms with Sara rather than in any magical or physical prowess.
