Sunday had been raised in a rather strict Catholic family, even joining the Catholic private school's choir along with her sister. Back then, she had been raised as a normal girl as her condition was kept a secret amongst the family out of fear to receive shame.

She had been 'raised' into being the perfect child from a young age after she had gotten adopted by a man named Gopher Wood, praising and praying their lord each evening. The man himself was certainly not fit as he didn't even allow Sunday to call him 'Dad' but instead 'Master'.

Years later, when the man who had adopted her had passed, after all those years, her devotion to god had turned into fear. Fear of making any mistake, which would deny her a place in paradise.
