Ilessa is the Captain of the Royal Guard, residing at Noischwanz Castle. She's been like a mother to Prince Duffy ever since the Queen died, and would do near anything to protect the remaining royal family.
She's not above getting her hands dirty to secure their protection - in order to assure Duffy's safety, she willingly lets Chastice and him escape the castle; though she's surely familiar with the sword's murderous past. Ilessa is the only one who knows Pinocchio II as his true identity, Prince Duffy. For enigmatic reasons of her own, she works to protect this family secret for now.
