Hermes Apocrypha

, or Lilim, is the grimoire of Lilith Asami who becomes sentient after absorbing Arata Kasuga's magic and therefore considers the two as her parents.

Personality
Upon becoming sentient, Lilim adopts the nature of an innocent child, often behaving in a friendly and cheerful manner. As such, she is quite cordial and open when interacting with others, although she is in particular attached to her master Lilith and Arata, whom she considers as her parents. Furthermore, Lilim is also compassionate and grateful to those she befriends, willing to even sacrifice herself to protect them from danger despite her sadness.

Appearance
In her original form as Hermes Apocrypha, the grimoire is a small brown book with a hexagram within a seal in the center, along with decorations on each of the four corners.

Upon transforming into a human, Lilim becomes a young female child resembling Lilith with red eyes and long white hair styled in double buns with a strand of hair braided on her right side. Her attire consists of a white collared tube top with a dark skirt over a pink skirt fastened by a large brown belt. Futhermore, she wears white opera gloves and thigh socks with brown loafers.

History
The Hermes Apocrypha was originally created by Hohenheim, the founder of the Outer Alchemic magic, who designed the grimoire to absorb the Demon Lord Candidate's magic which would awaken another of his creation, Last Trinity, within the Eternity Library.

After the demise of the father of alchemy, Hermes would eventually come into possession of Lilith Asami, the Trinity Seven of Luxuria.

Abilities
As the original grimoire of Hohenheim, Hermes Apocrypha possesses knowledge of Outer Alchemic of the Luxuria Archive, containing all spells which can be utilized by her current master. Furthermore, the grimoire can transform into her master's desired weapon for combat purposes.

Designed to absorb the Demon Lord Candidate's magic, Lilim is capable of becoming sentient, able to act and deliberate independently from her master. Even while in a weapon form, Lilim can still communicate with others through her astral form. Additionally, Lilim will never age as she is essentially immortal due to being a grimoire.

Notably, because Lilim also possesses Arata's magic, the Demon Lord Candidate is able to retrieve the magic within her to replenish himself. Through connecting to her, Arata and Lilith can essentially transfer into a dimension inside of her. However, this act will cause Lilim to revert back to a normal grimoire until she once again recieves his magic.
