Ghost Diary

Satsuki wields the ghost diary

The Ghost Diary was a diary written by Satsuki's mom, Kayako, when she was a student at the school. Kayako wrote about the ghosts she defeated in the diary. The cat Kayo leads Satsuki to the diary where it was hidden at the old schoolhouse. As well as the written information, Kayako sometimes drew a picture of the ghost.

Story

In episode 3, Raise the Curtains! The Cursed School Arts Festival! Kutabe, the diary shows how to trap Kutabe,

"November 12… Using a talisman and a spell, I put Kutabe to sleep in a statue of Jizo. It resided on the fourth step of the stairs, and it was a scary ghost who would turn the words spoken there into reality."

In episode 9, The Corpse That Wanders the Night - Shirotabi, the diary helps to save Leo,

"February 7 - Townspeople continue to be suddenly spirited away.  This must be the doing of a demon from the Road of the Underworld. It lures those who have become lost onto the Road [of the Underworld], then takes them to the River Sanzu. To make it back alive from the Road of the Underworld, hold up the talisman and chant that you want to go home."

In episode 10, The Tunnel With No Exit - Anamaneki, the diary is no help.

“I tried to put the Anamaneki of the Mamiana tunnel to spiritual sleep, but the regrets tying the ghost to the living world were so strong, I was drawn in by its bitterness and barely escaped before I was dragged completely in. For now, all I can do is to not get close to that tunnel.“

In Episode 16, The Public Housing Block That Consumes People! Nest of Evil Spirits, the diary tells how to put the forest spirit to spiritual sleep

"August 10. Souma appeared at Bridgit’s house. Apparently, this is a rare Feng Shui ghost, and the earth has varicose veins, like Bridgit. Gross! In order to make Soma go to spiritual sleep, you need to make a doll into a spirit receptacle, and then chant a spell in the middle of the earth's varicose vein. But unless you patch up the disturbance, a new Souma will take its place."
