Jigoku Shoujo (Hell Girl) - 1x04 - 第四話 聞こえぬ叫び声- Followmy.tv

Junko-chan's life has been plagued by eternal heartache and sorrow due to the loss of both her parents at a very young age as well as the recent loss of her best friend and loyal dog Candy. She's horrified to discover that the doctor who was supposed to be taking care of Candy's injured body had actually been too busy chatting on the phone at the time instead of tending to the dog's care. By the time he finally looked at the dog, it was too late and the poor soul had already left its injured body. It's obvious that Junko-chan's now going to utilize Ai's services to get back at Honjou-sensei for ignoring her dog's pleas of help, but she initially doesn't want to go through with it because of her fears of spending eternity in Hell.
