Since yesterday's blog post was about the Yokai medals, today's blog post will be about the Yokai Medallium from Yokai Watch. The Yokai Medallium isn't as important as the medals are, but it is important to the medals. The Yokai Medallium is a book that can hold the Yokai medals. However, it has been demonstrated in the Anime that the Medallium can also summon a legendary Yokai if certain Yokai medals are put in it. Although it can hold a lot of Yokai medals, it can be filled. This was also shown in the Anime when Nate needed a second Yokai Medallium to hold of the extra medals he collected. Other than holding the Yokai medals and occasionally summoning a legendary Yokai, the Medallium doesn't really have any other purpose. It's simply a safe place for the medals to be. I will also include a picture of the Yokai Medallium on here for reference as well. Enjoy!
