Senpai

Senpai (aka Taro Yamada) is a charcter in Yandere Simulator and the love interest of Yandere-chan. Unlike Yandere-chan, who is a nearly emotionless sociopath, he is a good person, but like everyone, he has his limits. For example he will get angry if Yandere-chan stands around him for too long, or will be horrified if she kills someone in front of him. He is about a year older than Yandere-chan, and is in a class one year ahead. 9 out of 10 of Yandere-chan's rivals are his love interests (the one exception is his little sister, who doesn't want him to have a girlfriend, and instead wants his attention).
