In Yandere Simulator, there are various characters that play important roles in the game. Mikaela Hyakuya is Yuichiro Hyakuya's best friend and a significant character. Info-chan is a crucial character who supports and provides information to Ayano Aishi, the main character. She shares secrets about Ayano's rivals and is a female student at Akademi. When you approach the Student Council members, a pop-up will appear, explaining their purpose. If you disable the tutorial, you'll receive an additional confirmation pop-up for removing them.
Osana is a popular student due to her high status. She will serve as a tutorial rival, but it's unclear whether she will be the only one or if there will be others. To find a student's locker and leave a note, you need to take their picture and locate the “Find Student Locker” prompt. In the future, you will only be able to ask each student for a favor once per day. Info-chan is resourceful and hard-working, as she spends her day collecting information using unknown methods on her computer.
Yandere Simulator offers unique gameplay elements, such as the ability to murder anyone who poses a potential threat to your pursuit of Senpai. As the game is still in development, there is no overall goal besides eliminating those who show interest in Senpai. One of the main features is the playable proof-of-concept, which provides a rough approximation of the planned gameplay. However, remnants of the earlier “rough proof-of-concept” code still exist in the game. This code was initially used to record footage for YouTube and pitch the game idea on Kickstarter.
LoveSick Mode, a variation of the main game, introduces darker tones to fit its theme. There are pop-ups in the game that appear to warn you of certain actions, such as cleaning up evidence before it's noticed and calling the police. Your reputation can be influenced by complimenting or gossiping about other students. Students are generated in the game based on data from a spreadsheet, making it easy to add new characters with unique appearances and routines.
The game also features interactions with Info-chan, who contacts Ayano through text messages. She offers a range of services and tells Ayano that she has observed her stalking Senpai. In terms of storyline, Info-chan wants Ayano to make Osana suffer, but her reasons for this are yet to be revealed. There are characters like Osana's stalker, who will play significant roles in the game's story.
Yandere Simulator has evolved over time, gradually shifting its shape and incorporating new elements. As you progress through the game, you'll encounter various pop-ups that provide additional information, such as when Ayano enters a clubroom for the first time. Ayano, the main character, seeks a fulfilling love life, making her relatable to players.
