Kawahara hosted the chapter on a separate section of his site and did not include it in the volume at any point. The only volume it was ever included in was a fan-translated version, it was not in the WN version, the LN version or it's official translation, or most fan-translated copies. Kawahara also pretty much denies its existence entirely.
