In order to attract fans, the Yandere Simulator game has embraced its title as a “simulator” with a unique twist. The protagonist, known as Cater, is a discreet but intense yandere character. The game's code includes an if-else chain that takes approximately 24.5 nanoseconds to execute per iteration, and on average, eight if statements are triggered per iteration. Cater is determined to become the top choice of his love interests and is willing to go to great lengths to achieve this goal.
However, he is disappointed by the lack of effort some of his admirers put into pursuing him. Despite feeling intense emotions for him, they don't make him their number one priority. To remedy this, Cater suggests creating a schedule for them, even if it's a small one, to help maintain their sanity. But he knows that Trey, one of his admirers, will eventually confess his feelings. Trey is determined to make sure there's no chance of rejection by isolating himself with them and becoming their sole source of trust and adoration.
Raibaru and Osana, two other characters in the game, were best friends before the events of Week 1. They spend all their time together, never separating despite only knowing each other for a year. Cater wonders if they should be focusing more on their studies.
Cater believes that having activities to do is crucial for the mental well-being of his love interests. He assures them that he will update the schedule according to their preferences. The Yandere Simulator game offers various mods, including the “A whole lot of Things Mod” by French Fries. As an observer of indie games, Cater often comes across different titles in forums and discussions. He compares the mentality of his admirers to what he sees on shows like COPS, Maury, or The Jerry Springer Show.
Despite his desire to be the primary focus of his love interests, Cater understands that each person has their own way of acting around him. Ace, one of his admirers, appreciates the guidance Cater provides in terms of how to treat him. Trey, another admirer, may need reassurance or time before approaching Cater. Trey often tries to suppress his feelings until they become overwhelming.
In the game, the main character, Yandere-chan, displays yandere traits, such as an intense obsession with a boy she likes and irrational and violent behavior towards others she sees as a threat. The Yandere Simulator game contains different storylines, including one where another character, Mida, attempts to seduce Taro, the main character's love interest. However, Taro is not easily swayed and may eventually fall in love with Mida.
Despite the efforts of other characters, Cater believes that all his love interests truly need is him. He acknowledges that he might come off as mean, but it's all part of his charm. Cater finds solace in his phone, using it as a distraction to avoid confronting his complex emotions. The game also includes other characters, such as Ayano, who may be caught committing a crime by other students who will then try to apprehend her.
