Story ideas in my mind

just a bunch of random story ideas in my head. maybe i will write something on them maybe i won't (_　_)。゜zｚＺ.

also you migh notice my ideas are more on the side of "A mysteries person changes the plot of the story rather than a OP SI(self-incert)". i just like the idea of someone outside interfering in the story by either helping others or using them(like a bookstore owners giving books with powers to his customers), rather than being a typical character who just wants t rule over others.
