game
腒 is a rare kanji whose core meaning is unclear. The given gloss "game" likely refers to hunted animals, but the kanji is not in common use and its standalone meaning is uncertain.
腒 combines the flesh radical ⺼ with 居, which likely provides the sound. The exact historical development is uncertain, and the character is rare.
The flesh radical ⺼ suggests something related to meat or the body. The right side 居 can mean "reside" or "dwell." Picture game meat stored in a dwelling after a hunt.
For キョ, imagine a hunter shouting "kyo!" as he brings game meat back to his dwelling: kyo -> キョ.
