After searching the Staff Room for a tranquilizer and returning empty-handed, you will find that Ayaka is dead and Sohta wounded. After speaking to Sohta, you will be given Misao's Arms.
Misao's head can be found in a minecart in the Bottom of the Well. To access the minecart, you must first go to the Science Lab and hide inside the large corpse, then wash off the blood in the Bottom of the Well.
Misao's legs can be found after finding Kudoh. Once you choose to watch him die, go back to the Boy's Bathroom, where you can find the car that hit Kudoh. Open the car door, and you will find the legs.
Misao's eyes can be found in a chest on the Rooftop, once the Lilles are put into the three vases found in the classrooms.
Misao's heart is locked in a capsule in the Science Lab. To unlock it, use the Boot Disk at the computer and enter in the correct code, then go to the back of the lab and enter another code into the console.
