User blog:Seieireppa/Here's what I've got planned for the rest of Arc 1 of GE:U

Next chapter (or the chapter after that), a certain character will appear whose origins will shed more light into Idenn's past (I've already discussed with this character's creator via PM, so he knows who he is). After that, more Aragami in the style of the Boundary Hannibal from before will appear all over the world, prompting Idenn, Ken, and the aforementioned new character will travel across the world, meeting with the other guest characters to fight them.

At the end of all this, when all the new Aragami have been defeated, the true villain will make his appearance, which will mark the end of Arc 1 and the beginning of Arc 2, where all the guest characters will fight against the villain alongside Idenn in a climactic battle for the ages... look forward to it!
