Godzilla X Devilman (Godzilla: Singular Point X Devilman Crybaby)

After the Great Catastrophe was stopped, Mei Kamino begins piecing back her life together. However, when a strange, demonic being named Devilman warns her about a mysterious, yet demonic entity "Devil Kaiju", leading an incoming war which the latter stated will be far worser than the Catastrophe itself. This not only has prompted both Mei and her demon ally Devilman but Yun and the Otaki Factory gang to race against time to find a way to destroy this demonic threat.

But the questions remain: What are the origins of this so-called unknown "Devil Kaiju"? Who's exactly is this Devilman and where did he come from? What if the only thing that can stop this "Devil Kaiju" and its advancing demon army is the Great Catastrophe incarnate itself, Godzilla? And what would ever happen if Mei Kamino ends up falling in love with Devilman?
