My fellow katakana tattoo connoisseur Alan has this to say:
As these things go, I guess this one is not so bad. It appears to be the names of people in a family, with the family name バンタ [Banta] written horizontally and the given names ジム [Jim], アネット [Annette] and タナー [Tanner] written vertically under it.
The tattoo artist did make a mistake in that the final stroke ー in the name Tanner should be vertical instead of horizontal. This appears to be a common mistake that we also saw on Kimberley's tattoo.
