The Touhou Character Sorter (東方キャラソート, Tōhō Kyara Sōto), or Tohosort, refers to any tool used to sort the Touhou Project characters, usually to show one's bias or favorability. It's often credited to “Haru” (ハル), who made the original sorter around June 2008.¹⁾

• Touhou Tier List Creator - The alternative sorter, a tier list creator, which gives you more control over the results. One of many,⁴⁾ this particular one was set up by “Mari” in 2020.

• You're supposed to avoid using ties. Whenever you use a tie, the sorter will assume that those two characters are true equals and will only show you one of the two characters, which can really mess with the results if you aren't expecting it or gradually change your opinion as you progress.
