Namino Tsuki

Namino was a young girl residing in Akeiwa village, part of the same household Izana was born in. She is the first person whose appearance Izana takes, shortly before killing her and setting fire to the village. [Spoiler] Izana's decision to steal her appearance was based not only on her being envious of Namino's beauty and upbringing, but also having seen her and Nagi Kaidou - whom Izana was secretly in love with - kissing.
