This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 旔 is uncertain. It visually combines 方 and 建, but the original semantic and phonetic roles of these components are unclear.
Since the meaning is unclear, focus on the shape: 方 (direction) beside 建 (build). Imagine building something in a specific direction, but the purpose remains a mystery.
For ケン, picture a builder named Ken who always builds in the right direction: Ken -> ケン, and his name is on the blueprint beside 方 and 建.
