Anyone remember what subject Mizuho Kazami taught? Apparently it wasn't math. The Please Teacher! anime/manga/light novel series is gearing up to celebrate its 10th anniversary despite premiering in January 2002. Then, as far as I can tell, the illustrations counting down to the celebration announcement made a mistake starting with 11, and when they apparently picked up on that, they skipped "4."
The announcement was that a "Summer Wind" celebration will culminate in an August 18th event at the Pacifico Yokohama convention center.
