Review Detail of EkoSun in The Devil's Cage

My favorite Novel many times better than about 99,99% of all Novels out there, a bit sad that it didn‘t showed more, in the end Kieran did had a Rank of about V or VI(don’t know his Rank after the last powerup, but I’m sure he isn’t over That Rank or on the top Rank at least),and we saw that this is not the max Rank, his teacher was somethink withing Rang IX or something(don‘t know if her Rank was 100% confirmed or it was just guessed in the Novel,but yeah she was many times stronger than him) in the last couple of sentences they said that he stayed in the game and continues fighting,I‘m sad that we couldn‘t see it , but overall loved the whole book.
