Tanuki and foxes are good at bewitching humans.
My friend enchants men with makeup all the time.
"I’m sorry I’m late. I was bewitched by a fox." "No worries. Things like that can’t be helped."
You've seen the word 化ける (to transform) before. Now we have a similar word. This word means to bewitch because when you cuss (かす) you are saying a magic word and bewitching the person in front of you. Imagine yourself yelling out cuss words, and every time a new enchantment falls upon your victim.
The reading is the same as 化ける, so make sure you know that word and you'll be able to learn this word's reading as well.
