President of the student council at the Holy Land, and granddaughter of of Pope Gen. Upon meeting Kenshi for the first time, Lithia describes him as a "Wild Beast," and calls him such instead of using his real name. Lithia becomes one of Kenshi's massaging victims after Mexiah hypnotizes him, causing her to be extremely sensitive to touch, and embarrassing her beyond words. She suffers from a weak body which is aggravated by her stressful workload and responsibilities, causing her to be vulnerable to illness and fainting. After Kenshi gives her a special herbal tea, much like the one he gives Ulyte, her condition begins to improve, as does her attitude toward him. It isn't until she meets with her grandfather, the Pope, that we see that she has some romantic feelings for Kenshi. Her sekijin's main weapon is a bow that fires energy arrows and her seikishi battle uniform resembles a business suit on top.

Before the battle to retake the Holy Land, Lithia gathers the student sekishi together from across the various lands and organizes the multi-national forces to fight Babalun. She also seems to be deathly afraid of the former head of the student council she served under. She leads the student forces into battle against the Babalun/wanderer forces.
