After buying a game called Romantic Thriller, a wizard named Riri appears in front of Anzu Hoshino. The wizard Riri makes a contract with Anzu in the form of pre-game details. Since Anzu didn't read it and went straight into playing the game she is forced into a real world dating sim experience. To make sure that she prioritizes romance instead of her hobbies, Riri confiscates all her video games, chocolate and her cat momohiki. Riri also makes it impossible to purchase any of these things. Along with that, Riri sends Anzu's parents off to the United States so that she will be living alone. While Riri is coordinating all these situations to make Anzu fall in love, Anzu becomes determined to never get into a relationship, no matter who comes along. However, will she be able to continue to refuse once she actually gets to know the love interests?
Romantic Killer was interesting because it felt different from most High School Romantic Comedy's. It kind of had a similar feel to Love Tyrant. While it wasn't something I could binge all in one go, I did enjoy watching it. The boys fit into usual tropes, but unlike the love interests, Anzu feels like someone you would actually meet in real life. There aren't any lewd scenes or any swearing. I would definitely suggest giving it a try if you want to see a unique Romcom.
