He wears a high-collared white undershirt with a mainly black and white overcoat, accented by rich burgundy and gold patterns. He wears a white cap featuring two black points with gold-lining and bat-like, ear-like ornaments. He has soft, dusty rose-pink hair, violet eyes, and a, "youthful" appearance. His Hydro Vision is located on his back, attached to an accessory with ornamental bat wings. His main weapon is a sword. He is a Deacon of the Church of Favonius in Mondstadt, serving as the lead singer of the church choir and a dedicated attendant of the Anemo Archon. Known as the "Herald of Barbatos," he mediates between the people and the Archon, presiding over prayers to provide divine guidance during times of trouble. He enjoys teasing, particularly with Venti (who is secretly Barbatos, but is disguised as a mortal bard, who has the title for the Best Bard in Mondstadt) and has a mischievous streak. Dahlia is frequently bored by the monotony of church duties and actively seeks out entertainment and drama, often wandering the city looking for trouble to resolve. Despite his playful nature, he is deeply devoted to Barbatos and is responsible for relaying feedback to the people of Mondstadt. While he loves excitement, he is ultimately well-meaning and responsible, ensuring that he does not neglect his duties or those in need. He acts like a "keen-nosed detective" to find drama and is capable of managing difficult personalities. He also loves VERY spicy food, but hates plain bread and other filler foods.
