Tiara is a cheerful and energetic girl, as depicted in both bonus illustrations and the spin-off manga. Unlike many others, she does not fear Supernaturals, instead finding them adorable, she openly calls the Mokke cute and even rescues one from a giant insect-like monster without hesitation.

Despite her sweet and kind nature, Tiara is far from a pushover. In a spin-off chapter, when two boys attempt to bully her, her older brothers, Teru and Kou, worry that she will become scared and cry. However, Tiara confidently shoves the boys away and responds with a sassy remark, showing that she is fearless and quick-witted when standing up for herself.

Tiara is a young girl with long, spiky blonde hair tied into two twin-tail tufts. Her blue eyes have light green flecks, giving them a distinctive look.

She often wears girlish clothing, typically featuring ruffles or floral designs, reflecting her cheerful personality. She is frequently seen with her Mokke companion, whom she calls “Minamoto Fairy.” On rainy days, she sometimes wears a raincoat with matching boots when going outside.

Tiara is born into the prestigious Minamoto family, a long line of exorcists responsible for maintaining balance between humans and supernatural entities. As the eldest daughter and youngest sibling, she is raised in an environment where exorcism and supernatural lore are deeply ingrained in their family traditions.

Unlike Teru, who is fully devoted to his exorcist duties, and Kou, who struggles with his moral stance on spirits, Tiara remains largely uninvolved in exorcism matters. However, her heritage suggests she may possess latent exorcist abilities, though she has yet to formally demonstrate them.

Spirit Lightning
Despite her young age, Tiara possesses an exceptionally strong spiritual energy, surpassing even that of her older brothers. She is capable of generating powerful blasts of spirit lightning, which can completely destroy hostile supernatural entities. Her innate exorcist abilities suggest that she has great potential as a future exorcist, making her a formidable member of the Minamoto Clan despite her inexperience.

Though Minamoto Tiara’s role remains minor, her existence adds complexity to the Minamoto family, offering a glimpse into the next generation of exorcists.

Her future involvement in supernatural affairs remains uncertain, but her heritage, personality, and curiosity suggest she may play a larger role as the story progresses. Whether she will follow in her brothers’ footsteps or forge her own path remains to be seen, making her an intriguing character to watch in Toilet-Bound Hanako-kun.
