^^Raiko is the extra stage boss from the 14th Touhou game, Double Dealing Character. She was a taiko drum who was empowered by the Miracle Mallet to become a tsukomogami (as were various other objects). Before losing the power of the Miracle Mallet she bound her soul to a drum kit from the outside world to keep her free will... somehow.
I guess wanting a "brutish girl" might be because as a drum she enjoyed being... um... hit.
edit: I believe the other two here are Tojiko, from Ten Desires, and... I'm not sure about the other one.
edit2: the other one is Iku Nagae who I'm not very familiar with. Apparently she's from Scarlet Weather Rhapsody.
