Seres has red hair with white tips at the end of four longer bangs tied into a bun atop her head and wears a black, butterfly-shaped hairpin with gold outlines, as well as a black and gold mask shaped after a butterfly that conceals her brown-red eyes. Critically wounded, Seres begs Velvet to devour her so she can use the strength of the Sorcerer's Ring to fight back. During the fight, Oscar turns one of his malakhim into a Drake that quickly goes in to attack Velvet, only for Seres to take the hit. However, they are confronted by Oscar Dragonia, who finds a malak with free will questionable. Initially, Velvet attacks the malak woman, but soon afterward, the two partner up and cooperate during the escape. Seres sneaks into Titania intending to rescue Velvet.


Knowing that is not a real name, Seres tells the boy of her plan before asking her son to forgive her for not being able to protect him. Before leaving, Seres goes to see the unborn child of Celica, now named Number Two.

Tormented by the memories of her past life, Seres takes it upon herself to free Velvet so she can kill Artorius. Artorius and Melchior Mayvin bind Seres's life to an oath to recreate the Sorcerer's Ring as a means to develop the armatus, an arte to which they plan to use to control Innominat. Eventually, this goes so far as to use Seres's own life. For three years, Seres watches as the Arthur she loved slowly fade away as Artorius's Abbey gain control over Desolation and plan to suppress all emotions as a means to permanently end the malevolence. Seven years later, on the next Scarlet Night, later known as the Advent, Celica's malak, Seres, regains her memories when she watches Arthur, now known as Artorius, betray her younger sister, Velvet and throw her in Titania. Both Celica and her unborn child were reborn as malakhim, but had their memories suppressed. Ten years prior to the beginning of the story, pregnant with Arthur's child, Celica Crowe fell into the shrine at the cape of Aball during a Scarlet Night which would become known as the Opening.
