Thank you for the compliment, Stone! I'm glad to see there are other people who like Kaguya-hime's story! I myself am hoping (even though it likely won't happen) that the Rider servant for Hinako in Lostbelt 3 is Kaguya herself.

I'd like to give a few comments myself on the matter of the 3rd skill. I personally wouldn't say the 3rd skill is OP actually. It's a targettable Guts skill, which itself is great, but the problem lies is that it comes with Invi and Max HP increase, which defeats the purpose of keeping a Servant alive. It can be used for 1 time invi, or to raise their HP for 3 turns, or to use to save them from death, but it comes with the cool down of 12 to 10. It's highly likely you'll only be using it once per quest. Once the invi is out, there is no way for Kaguya to keep anyone alive besides stalling out with her NP spamming. (On a side note, I did think about making the Elixir of Life her NP instead actually.)

In any case, thanks for sharing your thoughts!
