Sen no Rikyū/Komahime from Fate/Grand Order

I like the mix of elegance and eeriness of her design that perfectly reflects her identity as both the tea ceremony master Sen no Rikyu and the tragic figure Komahime. That pitch black eye with no soul behind them looks really unnerving and really sells the horror aspect of her character.

I like how her monster familiar gets more and more pronounced with each ascension too, in her first ascension it was just a pair of floating hands on her shoulder that you could easily miss, in her second ascension you can see it's full body, and in her third ascension i like how they merge into one with her hem transitioning seamlessly into the monster's hands as if they were roots and her tamoto transitioning into tree branches. The monster with giant hands can be seen as a metaphor for tea ceremony, where hands are essential tools for creating beauty and harmony. But here it's twisted into something grotesque, reflecting the duality of her existence: one of artistry and elegance mixed with betrayal and tragedy.
