Felicitá's personal butler. The bearer of Arcana Temperance (#14) and has the Mark on his tongue. He, Debito, and Pace are old friends. He is Jolly's pupil as well as his son. He’s been taking care of Felicita ever since she was a child. He’s amazing at all things domestic, including cooking. He also trained Felicitá, is rather clingy with Felicitá, and worries about her too much. It sometimes seems that he likes Felicità more than a friend. He loves to tinker with Alchemy.
