The recently published volume 14 of Saki contains several tables with characters data, similar to the ones that can be found in Ritz's blog site. The tables in the volume have additional information though. Most notably, there's a small bit of trivia for every major character and many of the minor ones too. Some of these bits can be surprising or funny so I decided to translate the tables, which I'm releasing now as a bonus to the chapter. I hope you enjoy them and the chapter too.

09/11/15 update: the links have been fixed. Also, changed the ages of Kazekoshi's coach and Fujita pro to 23 and 25, respectively (1 year older each one). According to Ritz's blog, the published tables had this minor mistake.
