The Morose Mononokean - Season 1 Episode 4

Abeno informs Ashiya that he won't be available for two days, since he is going to the Underworld to get some medicine. This makes Ashiya curious about the Underworld, and the Mononokean suggests that Abeno takes Ashiya with him. After detailing the rules, Abeno and Ashiya set off to the Underworld, and Ashiya wonders if he will get to meet the small fuzzy yokai (Fuzzy). When they get to the medicine shop, they find out that the medicine intended for Abeno was sold off to Big Boss Scree, and they have to wait for some time before the medicine is prepared newly. The two provide the shop some assistance, and in the meantime, Ashiya gets mistaken for a thief, and gets his hand nearly chopped off before he is rescued by Fuzzy.
