What is the chapter count for the regular 19 (+ 1) release of the manga? Ending on Chapter 47, the start and only regular chapter in Vol 19 + the anime´s ending, passes the smell test, even if only Wikia counts like this, as this was a monthly work. I have no idea where the 110 count that MAL has comes from, but I am willing to learn. The English Viz release doesn´t help one bit.

(The now easier to find 11 + 1 Japanese Bunkoban is its own thing.)

I also read EU/US comics and am a librarian.
