Ines is one of Alfred Drevis's test subjects. She always approaches Aya with a strange and unsettling smile.


Ines was a little girl, with short light brown hair, dark green eyes, and pale skin. She wearing a white sleeveless dress, and is always seen with a smile.

When Ines was alive, her appearance was much healthier and her eyes were more focused.


Ines was a cheerful and playful little girl. She seems to love animals, since she was testing her adoptive mother Monika's perfume to make sure that the animals would like the scent but ended up failing. She often giggles. Ines displayed a desire to join Aya's family; however, she is killed by the dolls in the incinerator room since she helps Aya burn the Creepy Doll. When Aya finds her dead, she mutters with a wistful smile, "I only wanted to be a part of your family", before fading away.


It is revealed in the Remastered version of Mad Father, that Ines lived on the streets as an orphan thief, until Dr. Drevis found and brought her to his home. While living there, he claimed Ines would be a part of his family and that Aya, who was only a newborn at the time, would be her little sister. While Ines held Aya, she was shown to be happy that she would be Aya's big sister. However, when Ines was sitting in Dr. Drevis' laboratory, the room goes dark and the sound of a chainsaw can be heard.

Ines first appears as the one standing behind Aya after the lamp goes out by the storeroom. The second time she appears, she is holding Aya's mother's perfume, and later tries to use it to lure some of the rats closer, but fails. The third time, Ines tells Aya how to break the barrier around the door. This information is what causes the dolls to rally against her and stab her repeatedly with scalpels in the incinerator room. In Ines final moments, the latter share her memories with Aya through a telepathic link, before tearfully expressing her desire to be a part of latter's family. Ines soon fade away, with Aya being sympathetic to the latter in silence.


Alfred - her adoptive father and killer.

Monika - her adoptive mother, their relationship is unknown.
