Moguro Fukuzou

Moguro Fukuzo is the titular antihero of the horror manga The Laughing Salesman and its two anime adaptations. He is a mysterious salesman who goes around making deals with potential clients and punishing them if they were to go against his advice.

Biography
Moguro is a humanoid creature of unknown origins who spends most of his time looking for potential clients under the promise of giving them a better life. The key issue with this, however, he gives his potential clients a few rules when accepting his deals. They had to follow his rules and if they were to cheat, refuse his assistance, or deny that they received assistance from him, he would punish them. Naturally, they would more often than not fail, and Moguro would punish them by turning his assistance against them, ultimately ruining their lives and continuing onwards to find more victims.

However, more often than not, Moguro is shown to not be wholly evil. In one of the episodes, Moguro is seemingly concerned when one of his clients were about to jump off a bridge to drown themselves only to realize they were just enjoying the view. He also makes it a habit to "protect" his client until the client inevitably goes against his suggestions. Of note, whenever he singles out victims, more often than not, he doesn't go after children.

In the second iteration of the original anime, he performs some magic tricks for a group of children and even creates more balls for the children to play with. In Episode 11B of NEW, when one of his recent clients, Ari, goes against his wishes, her daughter is in danger of being killed by an impending truck, she begs him to save her daughter having learned her lesson. He does so by DoNning both of them and prevents the truck from killing them. As her "punishment," Ari was made to audition to become an idol which, when you compare any of his previous punishments in both series, is a lesser sentence. There are instances where he would help people seemingly with nothing to gain, and they would tend to screw themselves over.
