It was a cold, dark night when Satoshi Mochida and his friends gathered in the dim light of Kisaragi Academy. The silence of the night was broken by their anxious whispers, as they prepared to perform the "Sachiko Ever After" charm.

Satoshi's younger sister, Yuka, clung to him, her eyes wide with fear. Yet she joined the others, determined to be part of the group, to share in the charm that promised eternal friendship.

Ayumi Shinozaki, the one who found the charm, directed the group. Her voice was firm, betraying no hint of the fear that was slowly creeping in.

Yoshiki Kishinuma, secretly in love with Ayumi, watched her from the corner of his eyes. He was skeptical about the whole thing, yet he was there, for her.

Naomi Nakashima, her heart beating for Satoshi, was at his side, her hand shaking as she held onto the charm. Her best friend, Seiko Shinohara, was next to her, trying to lighten the mood with her jokes.

As they completed the charm, the world around them began to distort. Their surroundings warped, and before they knew it, they were standing in the eerily quiet hallways of Heavenly Host Elementary School.

The school was a nightmare. The walls dripped with an unidentifiable substance, and the air smelled of rot and decay. The group clung together, their faces pale and shaken.

They heard whispers and cries, and occasionally, they would see shadows moving in the corners of their eyes. It was clear they were not alone in this wretched place.

As they ventured further into the school, they came across grisly sights. Bodies of students who had been trapped before them, their faces frozen in terror. This was the fate Sachiko had in store for them.

The group lost four of their friends along the way. Their screams echoing in the silent halls, their faces etched into the survivors' memories. The remaining five pushed on, driven by the hope of escape.

Amidst the horror, they discovered the true source of the school's curse. A young girl named Sachiko Shinozaki, murdered alongside her mother, was the root of all the evil.

Sachiko's spirit was trapped, full of hatred and sorrow. She lashed out at the living, forcing them to experience the same pain and suffering she had gone through.

The group decided to appease Sachiko's soul. They collected the remains of the students she had killed, a task that was both terrifying and heartbreaking.
