Syrup is a tan, feathered bird-like mascot who can shift into human form or transform into an aerial transport when needed. He first shows up in episode 1 of the sequel.
Best known for his delivery-boy work, Syrup comes across as somewhat arrogant. He's got amnesia and has spent a good chunk of his storyline trying to track down the Cure Rose Garden in hopes of recovering his memories. Turns out he actually worked there when he was younger, which adds weight to his quest.
At some point, Syrup took a job working for Eternal, the sequel's villain faction. He was tasked with delivering a letter from their boss to Flora, which is how he got tangled up with them in the first place. His reasons for eventually quitting remain unclear. The whole arrangement apparently tied into his search for the Cure Rose Garden, suggesting he needed their help or resources to get there.
Fans often note the growing bond between Syrup and Urara that develops throughout the series, with hints at a real connection showing up in episodes 4, 18, and 40.
