Lua is one of the four Japanese-styled mikos alongside the high elf, Aze, who appears in the elder council to show gratitude to Satou for saving Mia. She later nurses Aze who faints as she rewards Satou with the right to kiss her and Lua lends her an ear--when Aze failing to notice Satou--as she amusingly lets out her frustration at Japanese-summoned people.

Lua and Aze had known Satou to be the hero, Kuro, who fought Black Dragon Heiron as Lua had her familiar watching the latter half of the rampage between the black dragon and Satou, when Satou tries to deny it she reveals that Satou lets out spirit light and people with such a quality are abnormal and more than two rarely appear in the same time period. She encourages the shy Aze, to teach the means to suppress and make use of the spirits to Satou.
