Y/N L/N is the descendant of the last known person to be able to spiritually connect with apparitions. She was born with that capability and now takes on the responsibility of studying and helping the lost spirits in her school. Lately, she's been hearing of the 7th wonder, Hanako-san of the Toilet, and decides to give 'her' a visit. Unaware of what who and what she will run into as a consequence of this curiosity. *Reader insert with a bit of extra details
