This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 弻 is uncertain. It visually contains 弜 (double bow) and 㐁, but the component relationship is unclear.
The outer shape 弜 suggests two bows side by side, and the inner 㐁 looks like a person or object. Without a clear meaning, picture a mysterious figure between two bows, its purpose unknown.
For ヒツ, imagine the two bows hitting a target together: hits -> ヒツ, though the kanji's meaning remains obscure.
