Jūyō Shikaku is a female student NPC in the game Yandere Simulator.
Jūyō Shikaku is a female student whom can be seen wearing the default school uniform unless changed by the player. However, she always wears her lab coat and glasses. She has long black hair just below her bottom, and lavender eyes that are always behind her black-framed glasses.
Jūyō has the coward persona and comes off as uneasy. If she witnesses a murder and Yandere-chan begins walking towards her, she will crouch and beg saying that she will stay silent. If there are more than three murders she sees, she will crouch and offer to help Yandere-chan in a trade for her life.
If she does help, she will not kill. ----
During club activity time, if Yandere-chan approaches her she will smile at her and go back to doing her activity
She arrives a school at 7:07 am and goes to her locker, which is located between Kokuma Jutsu and Chojo Tekina.
At 7:15 she will walk through the plaza and go into the science lab standing by the shelf.
At 8:00 she will go into class 3-2 and sit in the back row in the middle.
She leaves class at 1:00 and will pace outside the science club room's door for five minutes before going to sit on the bench on the roof to eat. You can not poison her food because she will notice the signs of extra things being added to her food.
If Yandere-chan does this for three days she will become paranoid and not go up to the roof, instead standing away from the crowd during the time that people socialize.
