Poisoning

Another way to dispose of your rival or chosen student.

All Yandere-chan has to do is poison a students food, if she has that opportunity and the student is distracted.

When you poison a student in the game, regardless of ones persona type. Any student that finds the body will go get a teacher. The teacher will contact the ambulance instead of the police and the school day will end. "Of course in the final version of the game, other students will probably notice the girl loudly choking to death a few feet away from them."

Chemistry Lab and Study Points
In addition to the June 1st update, on the second day of the week. One student will break their normal path and sit at a bench to eat their lunch. As of the update, only Kokona Haruka does this. Before resuming to eat, Kokona will be distracted by Senpai and will go on to say that she wishes to confess to him. After talking to herself briefly she will return to eat. In the given time Yandere-Chan has, she can quickly poison Kokona Haruka's food.

To be able to poison a students food, Yandere-chan must first know which exact poison to take from the chemistry lab. The only way Yandere-chan can successfully get poison is by having enough study points invested in the Chemistry stat.
