Ahjisi is of the hunters who shows up in Bloated Man’s Grotto hunting Sinding.

She is part of a tougher group that will only be normally encountered if the player chooses to help Sinding. They spawn on the path the player already traveled from the entrance after speaking with Sinding, but if you choose to hunt then Sinding goes forward into the weaker group with Rissing, but if you choose to help him this tougher group will charge forward and attack.
