Blood Maiden that goes full yandere if you keep taking Arianna's blood over hers. (Possible non-con/violence.)

Gwyndolin is the lastborn child of Gwyn, Lord of Sunlight, and one of the deities who resided in Anor Londo during the Age of Fire. Due to his birth under the "feminine sign of the moon" and its influence that gave him a strong moon magic, as well as his lineage, Gwyndolin was raised as a female.
