When the Centipede-Elder Bairn appeared behind Nene.
It's pretty telling as a scary series when there are so many Nightmare Fuels in five episodes.
Episode 6 takes the cake.
Definitely a Blood-based cake with a serving of gore.
Episode 8 and 9. The invasion of the monster in the school makes episode 6 look tame.
Episode 12. Sweet merciful CLAMP, episode 12. Even a hardcore gore fan is gonna have trouble with this one. It stars off simple, with Tokizane, and Nene getting offed with a simple Off with His Head moment, and Nene getting repeatedly smashed into the pavement. Then the Elder Bairn goes after Nono, grabbing her, dangling her in the air by her legs, forcing her into the splits, and slowly pulls her legs off, her screaming in pain the whole time. Then comes the attack on the town. Helpless citizens being slaughtered, and an unlucky group stuffed into a bag, and mulched. Enjoy your dreams after this episode.
