Typically, the yandere character in yandere visual novels is overly possessive. They will go to great lengths to keep their love interest to themselves. This may include eliminating any potential rivals, either through manipulation or more extreme means like violence. They often seem sweet and innocent at first, but as their jealousy and possessiveness grow, their true nature emerges.
Harry is the most important character interacting with Yandere Cho. But we can't forget about Luna Lovegood. Luna might notice Cho's abnormal behavior and try to warn Harry. Also, Cedric Diggory's memory could play a role. Since Cho was Cedric's girlfriend before, his memory might haunt her and fuel her yandere tendencies, and this could be noticed by characters like Harry when they interact with her.
Often, it starts with the yandere character becoming infatuated with Naruto. They might start by observing him from afar and then gradually insert themselves into his life. Their actions are driven by their extreme love which can border on possessiveness.
The development should also include how she interacts with other characters. Her yandere behavior might not be obvious to everyone at first. She could be sweet and friendly on the surface, but there are little signs that something is off, like the way she clenches her fists when Naruto talks to another girl or how she subtly tries to isolate Naruto from his friends over time.
The main character is the yandere boy, whose personality is defined by his intense and often unhealthy love. Then there is the object of his affection. This character may be a very kind and innocent person, which makes the yandere boy's actions even more striking in contrast. There may also be some side characters like teachers or co - workers if the setting is a school or a workplace. These side characters can add more depth to the story by either being oblivious to the yandere boy's true nature or by trying to interfere when they sense something is wrong.
You need to develop his backstory well. Maybe he had a traumatic past that led to his yandere nature. For example, he could have lost someone important and is now terrified of losing the protagonist. In terms of dialogue, he should say things that are both sweet and a bit menacing, like 'You're mine and no one else can have you.'
Well, the main 'yandere simulator' game is mainly about the yandere girl's actions in the present time of the game's setting, like eliminating rivals in a school environment through various means. However, the 'yandere simulator the prequel visual novel' is likely to be different in that it will go back in time. It will explore how things started, the early relationships, and the events that led to the situation in the main game. The visual novel format also means it will be more text - based and choice - driven compared to the more action - oriented main game.
