In cycle 1, Yuno has become god and the Deus is dead, and after that, Yuno enters cycle 2. Why is Deus still alive after he is dead?
The same confusion also applies to the Deus in cycle 3. Cycle 3 takes place after Yuno and Yuki killed the other diary holders. At this moment, the Deus in cycle 2 has 'died' or become a red crystal-like stuff. How come in cycle 3, Deus still exists?
Furthermore, Deus is said to be the manipulator of space and time, both of which are eternal, and even so, they are mortal! The logic and causality of this premise seems quite messed up to me.
