The Stronghold 3: Mikachi

All of the Super Glitches have forgotten about the past and live their peaceful, human lives in a parallel Earth. But that isn't enough for Shaade, newly-turned demon with havoc to cause. He bids goodbye to Loki and vanished to another Earth - a planet called Mikachi, identical to the human world in every way apart from one thing. People with powers are hunted and Shaade will have to be very careful if he wants to not get caught...

This is the THIRD book in the Stronghold series, and the EIGHTH book in the Super Glitches series. The final book.
