Movie
Description
Sumire Hoshino, alias Perman No. 3 or Perko, serves as the deuteragonist in the Perman series. This 12-year-old famous child actress maintains her celebrity identity as a secret while actively operating as a superhero. Her teammates refer to her as Pako, despite her official designation as Perman 3. She conceals her civilian life from fellow Permans, finding greater freedom and comfort in her superhero role than in her constrained public persona.

Physically, Sumire has brown hair, typically worn short with an orange headband. Her civilian attire reflects her celebrity status through elegant dressing. As Pako, she wears a distinctive Perman outfit: a red helmet, green cape, badge, and pink frock. Later depictions in the Doraemon series show her with shoulder-length hair, and in "Stand by Me Doraemon," her hair appears black instead of brown.

Her personality exhibits duality. As actress Sumire, she presents as calm, polite, gentle, and respectful, adhering to societal expectations. As Pako, her authentic self emerges: tomboyish, brave, bold, hot-headed, short-tempered, and headstrong. She acts bossily, frequently scolding others and arguing with teammate Mitsuo Suwa (Perman 1). This contrast reflects her true nature, expressed freely only in her superhero role away from stardom's image management.

Relationships shape her development. With Mitsuo Suwa, she shares constant bickering underpinned by deep affection, harboring an extremely soft spot for him. She aids him first in trouble and meticulously attends to his preferences. This evolves into romantic love, culminating in her revealing her secret identity solely to him before his departure to Bird Planet, with mutual feelings confirmed and future marriage implied. Her interactions with Michiko Sawada involve friendship and rivalry over Michiko's interest in Mitsuo, leading to conflicts like competing to care for him during illness.

Across official media, including Doraemon crossovers, Sumire appears as a 14-year-old. In "What a Scoop! Nobita and the Secret Date," she helps Nobita evade paparazzi and reveals a locket containing Mitsuo Suwa's picture, identifying him as her cherished person. Other Doraemon chapters show her referencing a faraway lover she awaits, later confirmed as Mitsuo. She makes brief cameos in "The Almighty Pass" and "The Anything Airport." In the light novel adaptation of "Nobita and the New Steel Troops ~Winged Angels~," she learns of the Steel Troops invasion but acknowledges her inability to help due to lost childhood superpowers.

Her background includes living in Japan under an attendant's care in a condominium while her parents reside in the United States. Her name, Sumire, derives from the Japanese word for violet, while her surname Hoshino, meaning "field of stars," alludes to her celebrity status. Trivia notes her early character design featured blonde hair and her symbolic association with headbands across media.

Her character arc concludes when Mitsuo is selected as Birdman's successor. She emotionally discloses her identity exclusively to him, solidifying their romantic connection and implying a future together. This narrative extends into Doraemon, depicting her as an adult awaiting his return, reinforcing enduring loyalty and love.
