Argh. Disregard that - I was momentarily mixing up "doujutsu" with

should know better than to post while half-asleep...)
That's exactly what a doujutsu IS. The kekkeigenkai has two
components: the physical aspect (a Hyuuga's or Uchiha's eyes,
Kimimaro's bones), and the techniques, or doujutsu, the kekkeigenkai
enables (Sharingan, Byakugan, Tsukiyomi, etc.)
...hmm. That's what I thought at first, but then when Eimii mentioned
the bit about "techniques using the eyes" it rang a bell, and when I
went to look it up I couldn't find any obviously related (to either
side) meaning in any of the kanji with that reading. It would help if I
had an actual specific kanji to work from, but I've never picked up even
the translated much less the untranslated manga (and AFAIR the term was
never used in an episode title, so no help there).
