The princess of sweets. She sticks around people, and is easily impressed. However, when her childishness overloads, she will get scolded by her butler. It was also told that those moonshapes are the symbols of her country.

Luna has a sweet and innocent personality, although due of her status as the Princess of Candy Kingdom and as the youngest hololive member, she is a bit pampered and always asks for the older hololive members' attention, especially Natsuiro Matsuri's. In recent streams, Luna also showed hints of sadism and yandere personalities traits although it's not that prominent.

Being a 0 year old, Luna speaks in a childlike manner that almost resembles a toddler who just learned how to speak. She also often adds verbal tics like Nnnaaaaa~ (んなあああああ~) and Nanora (なのら) in her words. She also refers to herself in third person. Birthdates are the debut dates, since Idols are forever as young as they want :)
