Demon Invasion

Riku gets a note from his grandpa that he has left on a journey. When Riku goes to the destroyed shrine, he finds the site completely rebuilt. Nazuna tells Riku about the moon magatama and how it can allow people to enter and exit the world of Fukumaden at shrines. When Souma tells them that the Earth Style has already been in and out of Fukumaden, Riku and Nazuna take it upon themselves to go into Fukumaden. They end up in a grassy moss field. They use their Onmyou divination board to help them navigate, only to find two Earth Style Toujinshi, Kanna (Shikigami - Shuusui no Erekiteru) and Mozu (Shikigami - Hiiragi no Toubee).
