Teh Urn

• Head down to 1F, and grab the bat from the locker next to the infirmary.
• Head up to 2F, and enter the library. (Now we can warp!)
• Head down to 1F, and enter the boys' bathroom. Go to the right to trigger a cutscene. Go to the left to get the fire extinguisher, and go right to trigger another cutscene.
• Head to the girls' bathroom. Knock on the rightmost stall 3 times. Go to the leftmost toilet, and flush it. Go to the rightmost toilet to get the coins. (Always keep moving, and the ghost girl will never get you.)
• Head to the laboratory, and attempt to save Yoshino. Hide in the corpse. Open the capsule with the mandrake inside, and lure it to the upper floor. Read the notes on the table, and lure the mandrake further to the phone. After it faints, harvest the salt, and warp to the library.
• Head down to 1F, equip the Coins, and get some Pocari Sweat from the vending machine.
• Equip the bat, and head up to 3F to the principal's office. Destroy the vase, (Don't aimlessly mash Z, or you'll end up picking the wrong option and dying), and pick up the emergency exit key.
• Head down to 1F and outside into the well. Bash some boulders, but watch out for the spinning head. Head further into the well, and step into the pool. Head up, and get the head. Warp to library.
• Get some flowers from the vase in the library, warp again, and head up to 3F. Equip the flowers, and head into classroom 3-C. Place the flowers on desk 4E (in relation to the top-leftmost desk), and talk to Tohma. Warp to library, and talk to Miss Library twice: first to be her friend, and second to help with Tohma.
• Head to classroom 2-A and open the locker. Get the locker key, and place the flowers on desk 3D. Head to classroom 2-B, and place the flowers on desk 2B.
• Head to the long hallway on the right, and equip the emergency exit key to unlock the door. (Don't look back!) Head up to trigger a cutscene, and choose to not save Kudoh. Head down, and equip the Pocari Sweat. Once out of the long hallway, warp to library.
• Talk to Tohma to get the small key. Warp again, and head to the left looping hall. Equip the salt, and place it on the top 5th-from-left tile. Continue left, equip the small key, and sit in the chair for 11 seconds. Open the chest to get the boot disc, and warp to library.
• Head up to 3F, and equip the locker key. Head to the roof via the right hall, and open the chest to get the eyes. Warp to library.
• Head down to 1F, and talk to Ayaka in the staff room. Open the 2nd-from-left locker, and get the brain.
• Head to the boys' bathroom, and open the car door to get the legs.
• Head to the laboratory, and equip the boot disc. Activate the terminal, and enter the code 78450. Activate the other terminal behind the capsules, and enter the code 31269 to get the heart. Warp to library.
• Head down to 1F and to the infirmary. After the cutscene, look at Mr. Kurata's desk in the staff room, and the back to the infirmary. After another cutscene, get the arms.
• Head to the shrine outside, and equip the bat. Place all the body parts on the tables, and warp to library.
• Head down to 1F and up to 3F, and talk to Onigawara in the student council room.
