aah... the end of an arc, both for the story and in the reality
I was so sad when I read the news.
The artstyle was what got me interested in reading the manga in the first place,
which then led me to buy my first LN in Japanese.
However, if this decision was made out of consideration for the mangaka's health, then it couldn't be helped.
Best wishes to Jun-sensei, and good luck to the new mangaka.
also I would like to reiterate
my curiosity:
With this change in manga artist, and considering the novels have ended,
I wonder if this manga will then try to be published in parallel like some of the other novel adaptations.
