This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development is uncertain. The character combines 鬼 (ghost, demon) with 彡, but the original semantic or phonetic role of 彡 is unclear.
A ghost 鬼 with extra hair or markings 彡: imagine a shaggy, unkempt demon. Since the meaning is uncertain, this is only a visual mnemonic.
For ビ, imagine a bee buzzing around the ghost's hairy form: bee -> ビ, and the ghost swats at it.
