I am never a fan of depowering or removing abilities. Boxxy again loses some abilities. Admittedly, he has a metric crapton of them, but I do not like the trope of the depowered MC.
It feels like Neven Iliev wrote himself into a corner with the Keira persona and he was tired of dealing with it. So surprise, Boxxy gets multiple identity discorder. The solution, use up his IOU to fix it. The God of Chaos' solution, split Keira into its own entity and give it the job Hero of Chaos. This removes the Doppleganger's acting proficiency, hero skills (including Eyes of the Dead God).
The is my second least favorite volume behind volume 3.
