Kaiketsu Zorori - Season 1 Episode 49 Heaven and Hell

Zorori is in Hell but he doesn't plan on staying there long. Thanks to Akuma's idea, they've disguised themselves as angels in hopes of tricking the demons of Hell. It works and they're thrown out of Hell and told to take the Escalator to Heaven. Zorori realizes that if he goes to Heaven, he will see his mother again. He is overcome with joy and quickly runs up the escalator. Once in Heaven, he relaxes in a hot spring and meets an acupuncturist. All the while Akuma is uncomfortable being a devil in Heaven. Zorori starts looking for his mother after visiting Candy and Toy Heaven, but doesn't have any luck finding her. He searches Heaven after Heaven until he's told to draw a picture of her. People immediately recognize her and Zorori is able to track her down. Zorori reunites with his mother but the happy moment is cut short when she tells him he must return to Hell and demand Enma revive him. Based on book 31.
