Self-Defense is a variable determining how difficult it is to beat a person who can fight back against Yandere-chan's attacks. In the future, anyone with a strength level above zero can trigger the struggle mini-game.
In Yandere Simulator, if Yandere-chan takes a picture of a person and sends it to Info-chan, their Student Profile will appear with one of the variables being their self-defense. The higher the self-defense that someone has, the tougher the struggle mini-game.
Yandere-chan can defeat Heroes more easily if she increases her physical education rank. She will automatically win fights against Heroes and teachers if she joins the Martial Arts Club.
When in the Gaming Club, she can play a fighting game to temporarily increase her self-defense for one day.
These are the various levels of self-defense:
Because of a past incident in the 1980s, all teachers, including Kyoshi Taiso, are trained to have extensive self-defense. A struggle mini-game will initiate if they catch Yandere-chan and a Game Over will occur if the player loses the mini-game.
Strongest Person In School
Martial Arts Master
Mina Rai is the only student at school whose self-defense level is very strong. She is slightly weaker than Budo, but is still difficult to beat in the struggle mini-game.
Sho Kunin is the only student at school whose self-defense level is strong. He is an opponent whose mini-game is of moderate difficulty.
Shima Shita is the only student at school whose self-defense level is weak. She is easier to beat in the struggle mini-game, however she still has the capability to defeat Yandere-chan.
Juku Ren is the only student at school whose self-defense level is very weak. He is very easy to beat in the struggle mini-game, however he still has the capability to defeat Yandere-chan.
This is the self-defense variable most students have. All students who are incapable of self-defense do not have the Heroic or Dangerous persona, so they will not initiate a struggle mini-game. If a student near them is killed, they will instead act upon their persona and flee for help. The only time a student incapable of self-defense will attack is when they see Yandere-chan killing their sibling, loved one, or close friend.
Carries Pepper Spray
All students from the Student Council have this level of self-defense. Instead of initiating a struggle minigame, they will pepper spray Yandere-chan if she tries to attack them without stealth, or if they feel threatened, leading to an instant game over.

To increase their physical education, the player must allocate 20 points into the physical education stat per rank. The higher their rank is, the easier it is to beat Heroes and teachers. When starting the game, they are at Rank 1 by default. Rank 6 is the highest rank.
