Yandere Mode Where the HECK is the headmasters key?

[Mizato]

I have been trying to just play through Yandere mode and I get the key to the infirmary then turn of the power to avoid the gas. Then she gets all mad when I get back and opens the kitchen so I can get the first key. I get the three other keys and all the code numbers but where the actual HECK is the key to the headmaster's room? I searched the room the last key I got opens like 5 times and it wasn't there. No other rooms had keys. Where it at?

Not in Yandere mode. You start outside the school in yandere mode and she only starts to walk around after you fail to get in the headmasters office

You have to start the process of unlocking rooms and finding keys, in which case eventually you find the Headmaster's Office key in one of the rooms. if you're not finding the key, it could be a bug.

In Yandere mode, you have to go through a process of chaining locked doors until you find the headmasters key. You start at the kitchen (In the back sink, there should be a key), and then you follow each of the keys, and getting to code until you reach the headmasters room

However, so be aware there are traps built to kill you, specifically the poison trap, and the only way to avoid that is deactivating the power
