Before heading into the budding war, over merging Gehenna and Assiah (during "Testing the Fates"), Kamiki promised to tell Shiemi something if they both made it out alive. Some months after winning Shiemi is tired of waiting for Kamiki to tell her on her own, so our little Greenman Tamer decides to confront her.

Not long after Satan's attempt of merging the worlds Rin and Bon will face another onset of challenges. Will their relationship prevail, will his mother's dream become a reality, or will it all end by the Vatican?
