Knife Blade

The Energy Sword is an Easter Egg weapon in Yandere Simulator.

Gameplay
When Yanketsu Mode is activated, this sword will spawn in front of the school gates.Yandere-chan can wield it with one hand to dismember any students in their way.

The Energy Sword cannot be concealed in Yandere-chan's inventory and is seen as suspicious. If any student sees her holding the weapon, her reputation will drop by ten points at high School Atmosphere.

Yandere-chan cannot use an Energy Sword when fighting a Heroic student and will automatically lose, as the weapon is too unwieldy to use in close quarters. Yandere-chan can put an Energy Sword inside a cello case or a trash can in order to conceal it.

Energy Sword Animations
There are 4 killing animations for the Energy Sword depending on Yandere-chan's level of sanity.
 * High Sanity: A diagonal slash through the student's stomach.
 * Medium Sanity: Two diagonal slashes through the student's stomach.
 * Low Sanity: She knocks the student down to the ground and repeatedly stabs them from above.
 * Stealth Kill: She covers the student's mouth as they stab them from behind.
