Keima Katsuragi, the protagonist of the story, is a 17-year-old high school student attending Maijima High School Academy. At an early age, he acquired an obsessive interest in video games; now he is known as "The Capturing God (落とし神, Otoshi-gami?)" in the gaming world for his legendary skills in "capturing" any girls in dating sims. But ironically, he is called otamegane (a derogatory portmanteau of the two words otaku and megane-"glasses") by almost everyone in his school due to his extreme devotion to videogames. Despite himself saying he likes girls, it's the perfectly theoretical and beautiful girls of the game world that he prefers, not the girls in reality. His love for games is such that he even goes into withdrawal if he doesn't play games enough and he has the bad habit of locking himself in his room and playing games for days on end when he's depressed.
