Ghastly Prince Enma Burning Up - Season 1 Episode 8 Mysterious! The Demon Who Waited Patiently

The school is covered in snow and the Yokai Patrol is attacked by a group of demons, but Enma is too cosy under his kotatsu to do anything about it. They attempt to remove the Blaze Circlet from Enma's head, but Enpi arrives, telling everyone that if it's removed, Enma's full power will be unleashed and destroy the world. As Enma becomes traumatised by memories of his parents, the demons try cornering Yukiko, Harumi and Enpi, but end up getting themselves killed. After the battle, Enma recalls his promise with his parents was to be a good boy so he could get a load of chogokin toys which never came.
