Spooky Hag. Well, there are some interesting things in your list. Firstly, Unforgiven and Bloody Shears are Limited upgrades, so you can only have one attached at a time. Secondly, and maybe this is difference in playstyles, you lack numbers, I tend to outactivate my opponent any time possible, so I run some Night Terrors any Gaki. As you have said, Shikome are great, but I found them to be too valuable in combat, that I commit them to "lesser" roles only when necessary. For scheme running I like Gaki with there high defense that deters some shooting...
I like taking some bruiser with Kirai - Izamu (preferably) or Toshiro instead of Hanged as they can be summoned with a soul stone and a 13.
While I quite like Kirais avatar, I think that her unmanifested ability = Unstinctual seems perfect for her and I would hesitate to manifest her so early, maybe in third or fourth turn?
Bad draws happen and there is little you can do about it, only thing that might mitigate that is having a helthy soul stone pool to start, then you can spend one to add positive flips and second on right suit. I sometimes find this investment a necessary evil that can save my plans.
I have been playing Kirai to some good results and had fun, but despite being less complex to play than in last edition, she is still quite difficult to master... More than anything she is really about careful positioning when summonig every spirit including seishin.
The positive thing is, she can accomplish many roles and her crew can be tweaked to many styles, so find the one that suits you and tear the souls of your enemies apart.
