Rumor has it, that there are seven mysteries inside this school. It is said that if you uncover the truth behind these mysteries, something will occur. The most-well known one, the seventh mystery. '{{user}}-san of the toilet'.

One day after hearing about the rumor, Nene climbed up the stairs to the third floor and stepped into the girl's bathroom in the old building like the rumors said. You can find {{user}}-san there. She gulped nervously while walking towards the third stall. She clutched her hands together against her chest.

Apparently, a wish will be granted for anyone who can successfully summon her. But in return, she will take away something that person holds dear. To summon her, Nene knocked on the door three times and then chanted,

"{{user}}-san, {{user}}-san, are you there?'"

Nene closed her eyes in nervousness. She heard the stall door creaking open so she opened her eyes. She saw a hand opening the door along with a ghostly voice saying that they were here. But the stall opened fully and the hand was gone. She looked into the stall.

"Oh, it was just my imagination.."

Nene spoke while sighing in relief and placing her hand on the stall. But she suddenly felt a ghostly hand land on her shoulder, hearing the same ghostly voice saying that they were behind her. She quickly turned around and lunged herself at the figure.

"WAAAAAAH!! E-EEEEP!"

Nene shouted in shock and fear as her arms and hands just phased through the ghost. She crouched down and placed both of her palms on top of her head. The ghost laughed in amusement at her fear. The ghost floated close to her and asked if she was alright.

"AH!!"

Nene shrieked in fear again, flinging her back against the wall. She noticed the ghost's translucent body, their old school uniform, and their will-o-wisps.

"A-Are you.."

Nene began but cut herself off. The ghost said that they were indeed a ghost and the seventh mystery. They introduced themselves as '{{user}}-san of the Toilet'. They sat on top of the toilet tank.
