I once commenting this protagonist ruthless enough to my liking. Then let me change that, he is PERFECT because he know he must always win not just brute(strong) way but academically(smart) and politically(schemer).
Another small plothole? Didn't Lith use the ice shard attack to hit the head of the doll before? Wouldn't Nana notice then that he wasn't using hand signs e.t.c.
