Ione, like Casimira is as gentle and kind as a mother figure can be. However, like all mother's and mother figures, she has a vicious and uncompromising will to protect and guide all those under her care.

Ione acts as the mother and guide to all those in Marcelino Estates, humans and other Tokotas alike. When taken out on Missions, she usually attempts to take the lead even ahead of Lennox. Especially if it has anything to do with a dark confined space.

She has a very close bond with her owner, Casimira, and will shred heaven itself if she thinks it's harming her master. She also seems to attract all types of creatures to her. Whether it be the stray dog harassing the village children for scraps, or the Eviscerator hatchling just looking for attention. Her and Casimira are rarely apart and seem to be nigh inseperable.
