Rosaria is known for his cold, intimidating, sharp words and behavior. He's not much of a talker and hardly ever finds himself talking to anyone if not required to. Rosaria will often even try to avoid his duties as a nun in the Cathedral, trying to leave as soon as he can if not mandated to be there. Rosaria is pretty tall standing at 5'9.5" / 176.5cm. When he gets close to someone, Rosaria suddenly becomes such an adorable sweetheart. Completely different from his usual cold demeanor.
