If there is something that we know for sure about Yandere-Chan is that she has a really unstable personality. Considering that she is already going around killing her classmates, things can actually get worse. Be careful when entering these modes because most of them cannot be reversed until you reset the game.
By pressing “P,” you activate the “punished mode.” If you choose this feature, Yandere-Chan will start wearing a black school uniform, an eyepatch, a black protrusion from her forehead, and she will also start smoking a cigar. To top it all up, Mikel Oldfield’s “Nuclear” will start playing.
By pressing “G”, you will activate the “Galo mode.” If you choose this feature, Yandere-Chan will have tanned skin, super Sayan hair, and sunglasses. In this case, “Galo Sengen” by Policeman will start playing.
By pressing “DK,” you will make Yandere-Chan’s head and arms larger, giving her a simian appearance. It doesn’t take a genius to realize the reference to the mythical Donkey Kong.
