Syrup is a tan-feathered, bird-like fairy adorned with green streaks on his head, a vibrant red scarf, yellow webbed feet, and a distinctively pale face. In his youthful human guise as Amai Shiroh, he sports scruffy hair, an orange uniform, and a practical blue waist bag. His adult human form evolves into a more mature appearance with ruffled hair, a light brown vest layered over a beige long-sleeved shirt, and his signature red necktie.

Raised by Flora, Syrup was tasked with delivering a critical letter to Boss until an attack by Anacondy erased his memories. Manipulated by Eternal’s false promises to restore his past, he grew resentful of Coco, whom he accused of deceit, and clashed with the Pretty Cure team. Yet Urara’s persistent kindness eroded his distrust, fostering a bond that redirected his path toward music—a passion instrumental in awakening the Cure Rose Garden’s roses through her melodies.

Driven by lingering anger and Eternal’s influence, Syrup initially betrayed the team, attempting to seize the Rose Pact. However, the Cures’ steadfast loyalty during his defiance prompted him to shield the Pact instead, cementing his redemption. His devotion to Flora, whom he cherished as a mother, deepened after her death, compelling him to safeguard the garden she entrusted to him.

Years later, Syrup vigilantly oversees the Cure Rose Garden, nurturing new Time Flowers tied to Nozomi and facilitating correspondence between allies. He intervenes in pivotal moments—rescuing comrades from Shadows, guiding Urara through struggles—while embracing music as a lifelong vocation, mastering the guitar and co-writing songs that echo her enduring inspiration.

Once aloof and guarded, Syrup matured into a compassionate protector, retaining his fondness for pancakes, blunt honesty, and diligent nature. His reconciliation with Coco and Nuts, alongside his unwavering commitment to collective goals, mirrors his journey from a solitary outcast to a cornerstone of trust and unity.
