So, I'm assuming the Fox shrine priestesses are not as kind as we thought?
Oh no they were doing it for a reason. To get Hana.
when miko prayed to the shrine her wishes were thus.
1) "Please do something about that creepy thing following Hana around"- get rid of the spirit following hana and consuming spirits attracted to her aura.
2)"Please help ill do anything to have that thing stop following her"- Helpful hint: when dealing with gods,spirits, or the fae never promise 'Anything'. Unless the situation is truly desperate (and even then be prepared to give up more than you think). Not that she knew that was a spirit shrine instead of a holy shrine but regardless.
3) "Please lift this curse from hana and help me out when you are at it" - Miko sees the large life aura as a curse since it keeps attracting dangerous spirits towards her friend not knowing exactly what it is.
Helping her out is more ambiguously worded so they gave her 3 times of active assistance. Now they defended her from the last ones because she was close to their territory and she needs to repay them (hence being insulted by her offering)
Now how to lift the "curse" that hana has AKA: reduce her aura to stop attracting the spirits towards her. Since miko promised anything they will ask or demand hanas aura as tribute (and since that is her lifeforce.........).
