This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The historical origin of 徍 is uncertain. It visually combines 彳 (step) with 圭 (jewel tablet), but the exact development is unclear.
With no clear meaning, focus on the shape: a step 彳 beside a jewel tablet 圭. Perhaps it once described a ceremonial walk, but treat its meaning as unknown.
For アイ, imagine an eye (アイ) watching a rare ceremonial step: eye -> アイ, and the step 彳 carries the jewel tablet 圭.
