Kami nomi zo Shiru Sekai S01

Katsurougi Kima is a second-year high school student and a professional player in a simulation game, and no two-dimensional girl can resist his charm and be known as the God of Capture in the internet. He makes a contract with a girl named Elsie. Elsie, who thought Kima was an expert in capturing real girls' hearts, asks him to help her capture evil spirits that hide in the empty hearts of girls. By falling in love with these girls, they can be removed from their hearts. However, it becomes clear that Elsie made a mistake and Kima has no expertise in approaching real girls. But the contract cannot be broken unless both parties die... and now Kima must capture the hearts of real girls to save his own life and Elsie's. But for someone who believes "reality is a ridiculous game", this seems impossible.
