Pino manifests as Rody Soul's Quirk "Soul," appearing as a small pink bird-like entity. Continuously active, she externally embodies Rody's genuine emotions and thoughts. Her existence directly links to Rody's physical and mental state—injuries or physiological changes affecting her stability and visibility. When Rody suffered a severe chest wound from a laser turret and neared unconsciousness from blood loss, Pino temporarily faded, demonstrating their shared vitality.
Thematically significant, Pino's name references pink coloring, Japanese bird chirping onomatopoeia ("piyo piyo"), and Pinocchio’s lie-exposing nose growth—paralleling how she reveals Rody’s true feelings to expose dishonesty. This inability to conceal emotions forms a key weakness; Pino’s reactions contradict Rody’s false statements, making deception nearly impossible. Despite Rody’s male identity, Pino uses female pronouns, resembling opposite-gender daemons in Philip Pullman’s *His Dark Materials*. Thematically, her truth-driven connection contrasts antagonist Flect Turn’s isolating Quirk "Reflect," which repels physical contact.
Pino remains integral to Rody’s daily life. After his father abandoned the family to join Humarise, forcing Rody into petty crime in Otheon’s shantytown to support siblings Roro and Lala, Pino assisted with childcare and domestic tasks, often joining their playful interactions. During critical events, she proved vital. Rody used her as a distraction while evading Izuku Midoriya. Later, when Rody feigned betrayal by handing Flect Turn the bomb deactivation key, Pino’s anxious fluttering revealed his true loyalties, allowing Midoriya to recognize the ruse. Her autonomy surfaced when she woke Midoriya after Rody attempted to flee alone with a briefcase, reflecting Rody’s subconscious desire to be stopped.
Pino’s pivotal contribution occurred during Humarise’s Trigger Bomb disarmament. As Rody raced to input the deactivation key, a laser turret severely wounded him. Nearing unconsciousness, a weakened Pino retrieved the key and inserted it with less than a second remaining, preventing global catastrophe. This established her as an independent actor beyond an emotional mirror.
Later, Pino accompanied Rody and his siblings to Japan, where her behavior betrayed Rody’s nervousness about losing them in an unfamiliar country. During a reunion with Midoriya and U.A. students, her presence highlighted her ongoing role as Rody’s emotional indicator, particularly his joy at receiving pilot-themed gifts symbolizing his aspirations.
