A mysterious character who appeared as a voice in Arisella's mind, isolating her room from the world itself according to her words.
He claims to be the messenger of the 'Heavenly Father', transmitting to Arisella the reason for his reincarnation, supposedly because he had been selected as a sacrificial lamb to save the "Daughter of God" according to the criteria of the Guardian Angel who watched over her.
However, it is unknown whether the mysterious entity's words should be trusted, especially since Arisella never questioned her death as Amael Parker from the beginning, accepting that she was only reincarnated as if it were the most common thing, nor did she doubt anything he said the Messenger.
Whether there is a greater plan or whether the Messenger was telling the truth, only time will tell.
