Nao Yasumori

She invites Kirishiki Seishirou and Chizuru into her household, which resulted in her being bitten and eventual death. Because Nao loves her family very much (she was raised in a household of alcoholic parents, who left her when she was 6), she returns as a Shiki and kill her son Susumu, her husband Mikiyasu, her mother-in-law Setsuko and her father-in-law Tokujiro. However, none of them returns to life, and Nao then targets the Yasumori main house out of jealousy, killing her sister-in-law Jun. Nao is eventually brutally staked to death during the Shiki extermination led by Ozaki Toshio.
