Chicha Amatayakul as Nanno, a mysterious girl with supernatural powers and an enigmatic origin. Nanno serves as both
guide and punisher to humans who hide secrets, perform harmful acts to others, and have selfish desires. Nanno is revealed to be an
immortal entity that has the power to expose the lies and misdeeds of everyone she meets serving them the appropriate punishment no matter how big or small. Nanno is neither good nor evil in her
crusade as she judges everyone equally, and while she feels no regret towards hurting people she only hurts those who have harmed others. She will however help those who are not inherently bad but are lost or trying to do better for themselves. Nanno prefers taking her time and planning how to deal with her marks before ending her mind games with satisfactory results. Nanno's outfit consists of her short medium-length, bowl-cut/bob hairstyle with bangs, female school uniform, and her inhuman-like cackle. She has similarities to the
Junji Ito manga character
Tomie Kawakami which was credited as an inspiration for the role, according to Amatayakul. • Chanya McClory (season 2) as Yuri, Nanno's rival. Yuri was originally a victim Nanno attempted to help after she was mistreated by two rich girls who
blackmailed students, including Yuri, with
sex tapes of her and others being
raped. However, Yuri had already planned for revenge on the girls since her assault, and instead of listening to Nanno's advice she used Nanno as a sacrifice for her plan, hiring two men to assault and film the girls, in the same way Yuri was. Yuri's plan backfires however when the men also kill Yuri to hide their crime, drowning her in a bathtub that a bleeding Nanno was later placed in. Nanno's blood revived Yuri, giving her the same powers and immortality as her. Unlike Nanno though, Yuri prefers to spread chaos and get Nanno’s marks killed by others using lies and manipulation. Yuri shows signs of being
sociopathic and has no remorse for her actions. Yuri's outfit is also a traditional female school uniform, with her hair tied in a ponytail using a red ribbon. == Episodes ==
