The story is progressing in a good and comfortable way, I think the only drawback is that this story is monthly the time between chapter is big that makes the chapter seems short sometimes, welp i do think it is the best way for the author to do his work right with this level of art weekly would be tiring.
Great chapter this month, Kai sure has grown a lot, I don't see that nervous boy anymore and his thought process is refined too, he is using his gullible looks for his advantage and can take decisions on the spot ( well sure that he is in this situation because he got caught in the queens rhythm, but you can't expect him to play well against someone like that, the Ara-Ara i strong in that one ).
Ah.. one more thing, the doctor is the culprit, it is as obvious as our little reverse trap.
