How many chapters is this? It just says Volume 13 for end.

It's a bit complex. Originally the whole series was collected in 13 tankoubons, but the raws are taken from a Kazenban edition with more chapters and extras per volume collected in only 9 tanks.
But it's essentially the same chapters.

DUN DUN DUUUUUUUUUN

Also I think there's a mistake with the university names when talking to the cop. First it's "Yotsuya", then it's "Yatsuya". I assume it's meant to be the same.
