Watch Tayutama Kiss on my Deity OVA Online

Yuuri Mito is a typical, normal Japanese teenager. He goes to school, works on people's motorcycles and performs exorcisms. Okay, that last part's a little bit unusual, but his family lives in a shrine and they do that sort of thing. Still, you would think he'd know enough to be careful with an ancient relic he finds in the woods, especially when a mysterious goddess appears and tells him to leave it alone. Unfortunately, despite Mito's best efforts, the seal gets broken anyway and a number of dangerous "tayuti" that it held in stasis get loose. This is bad. Mito also ends up with a beautiful goddess girl who decides that she's going to marry him. This might not be so bad. if he wasn't already caught up in the middle of a war between the entities he's released. The flesh may be weak but the spirit's more than willing to compensate.

At Yachimata, there is a legend of a deity named Tayutayu-sama who protected the area, but this deity and other so-called “Tayutai” have been lost in time. Mito and his friends discover a relic on the school grounds with mysterious patterns on them. Then, at the opening ceremony of the new school year, an equally mysterious girl named Mashiro appears before Mito. Mashiro is somehow tied to the relic and the legend of Tayutayu-sama.
