Bruno, father to Lubicchi and husband to Lola, lived within the perpetual smog of an industrial town where the sky remained unseen. Working as a tailor, he held an unwavering conviction in stars beyond the smoke, sharing stories of them with his son. This belief defied the town's accepted narrative, inviting widespread ridicule. He and Lubicchi crafted a bracelet symbolizing their bond and his teachings about the hidden sky.

Bruno actively contested the town's disbelief, openly proclaiming the reality of stars and the world above the smoke. His actions led to a confrontation where doubting townspeople destroyed the bracelet he made with his son; during this struggle, Bruno gave his own bracelet to Lubicchi. Following this, the authoritarian Inquisitors subjected Bruno to severe persecution. His defiance culminated in death: chased to the Forbidden Cliff, he jumped and was consumed by monsters.

The town initially told Lubicchi Bruno died because monsters punished his actions, but later revelations proved the Inquisitors directly caused his demise. Bruno's legacy became inseparable from his vision of the world beyond the smoke. His stories and the bracelet he created served as vital catalysts for Lubicchi's subsequent journey with Poupelle, a being made of refuse. This journey exposed the town's hidden history of isolationism and environmental manipulation, ultimately fulfilling Bruno's belief in the stars and dissolving the oppressive smog. His teachings on perseverance and truth endured as foundational motivations for the town's liberation.
