Hanako and Y/N were friends while they were walking with the living. Y/N died at the pond on school ground's and became the 8th wonder. The young girl pretended to be a student at the school and quickly became friends with Nene Yashiro. The two friends often heard rumors about "Hanako the bathroom ghost," Y/N of course already knew who the 7th rumor was, infact the two visited each other's boundries when they had nothing to do. Yashiro decided to drag Y/N along with her to summon Hanako. The H/C girl was against the idea of going to the third story bathroom because she didn't tell her ghost friend about visiting and was scared he would call her, her real name, Y/N called herself Kayano Agatsuma. The female apparition hated lying to Yashiro but it's best for both of them that she didn't know. (One of the books I've put the most effort into)
