BTW, for those interested, a while back I made a series of Icons for the Smash Bros. Roster Maker that focuses on the characters from the SW3 versions of the Murasame Castle characters, so I'm going to share them here with y'all.
Ayame is a composite character introduced in SW3's version of Murasame Castle, shes meant to represent all the maidens you can find hidden in Murasame Castle and can save for bonus points. Then the four demonic Castle Lords: Aosame, Akasame, Ryokusame, and Momosame. They're humanoid in appearance but if you play the mode in Nightmare Difficulty you fight them as their true demon forms.
