Author’s Comment
"Every volume, I always worry about what to draw for the picture above (left) these segments. This time too, I was thinking “I wonder what I should draw~” and just started drawing whatever. If there are any psychiatrists or psychologists among you readers, can you please tell me what is up with my state of mind."
