尾 can be read as either "お" or "び". They both mean tail, but the "び" reading is a suffix. Which would make sense, given that their names are 7 tails (Nana-bi) and 8 tails (Hachi-bi).

Also, extract her sprites from the arc.nsa, and you'll see that they've been romanised as hatibi, supporting the び　suffix meaning. And that's coming from the guy who made the game itself!
