A vampire Yurine would make Kotori feel fear. I mean, Kotori will react like Jashin chan always do, and you know how it ends... Also, all the Kurumis would get curbstomped by Yurine's, like she did with all the Jashin chan haha. Obviously, it isn't serious. But would be so fun to see how Yurine beat the spirits like she always do with Jashin chan. Also, Tohka and Tenka would like Yurine, because she can cook like gods.
