(Chapter 1) Sacrifice

Based off of the rpg game Ib's 'Sacrifice' ending, this fanfic talks about Garry in the real world and Mary trying to help him recover momories. But what happens when new mistress Ib is met with a strange being and uncovers her true powers? Will Garry go back to the gallery in search of his beloved, or will it already be too late?
(In the fanfic, Ib is 16 and Garry is 18. But since Ib hasn't been exposed to many stuff yet, she's still quite innocent. P.s. Mary is 17)
