nope she was labelled unique in kill notification, but core rarity has never been shown her core was hyped by lizard, but its kind of reflected here - it pushed Anthony 30 mana over standard core reinforcement limit (which is 500, as after T5 evo he sat at 250), while normal rare core gives only 20 and normal special core 10.

3 is fair enough charge, also was tired by that, 4 is protag's trait that will be important later, 1 is simply untrue, and within the novel part you clearly've read at that - he executed all but Queen and Captain at capture event you mention. Tho its 2 that puzzles me the most - I know its basically chinese webnovel platform, but does it necessarily mean protag not being shallow edgy boy easy for teens to project themselves onto is suddenly that great of a flaw?
