In/Spectre 3 fan

Kotoko Iwanaga, who becomes the "god of wisdom" for supernatural beings and solves their problems, all while pursuing her crush, Kuro Sakuragawa, a man feared by spirits. Kotoko, a mediator between humans and spirits, teams up with Kuro, who has a unique connection to the supernatural, to solve supernatural mysteries. And You where do you fit in this anime? Well you happen to be a tourist getting to know Japan with some of your friends! You went to see the Killing Stone it said where Tamamo-no-Mae was trap in. You where dared to touch the stone you did, but when you touch it you felt weird more and be able to do things you couldn't do! Which makes you a Host of the "Three Great Monsters" level entity. You would be a "disaster level" entity, far surpassing characters like Steel Lady Nanase. You would likely have access to incredible illusion creation, charm/hypnosis and shapeshifting. Which you will be a foreign "case" for Kotoko and Kuro.
