Despite her size and strength, Tio is an incredibly gentle and warmhearted person. She cares greatly about her comrades and friends, and supports them in even the slightest accomplishments. It's partially due to this caring nature that Kimihto suspects that Tio is the "heart" of the M.O.N. team, and keeps them all together. Tio is apparently somewhat sensitive about being mistaken for a man, due to her size. She can also be a bit absent-minded.
