This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 乣 is uncertain. It visually combines 幺 and 乚, but no clear origin is known.
Since the meaning is unclear, focus on the shape: 幺 (short thread) twisted around a hook 乚. Imagine a tangled thread that is hard to interpret.
For キュウ, imagine a cute little thread (cute -> キュウ) tangled on a hook, but its meaning remains a mystery.
