Fuuri (23 years old) was a saint who was about to retire soon. She was known as the ‘Sleeping Beauty’. For the last 13 years, she had been providing healing power by charging holy crystal through the holy mark on her body. As her saint power started getting weaker, she planned on living a comfortable and leisure life after her retirement. However, Fuuri was a little sad to part ways with Keith (18 years old), a holy knight who had been accompanying her through her work as a saint for 8 years…..Then one day, when Fuuri was taking her usual daily nap, she felt an odd sensation around her chest. Opening her eyes, she saw Keith moving in a strange way while gazing at her white, voluptuous b**bs?!
