Iris is the first princess of the Kingdom of Belzerg and is just 12 years old. She stands out for her elegant royal aura paired with a gentle and fragile vibe. What really makes her interesting is her close and playful bond with Kazuma Satou—she even calls him "big brother." She is surprisingly powerful, famous for using a legendary sword and taking down strong enemies in a single hit.
