Isabella

Isabella (イザベラ) is a demon from Mass for the Dead.

Appearance
In her human form, Isabella appears as a busty dark purple long-haired woman wearing a dark corset-like dress that reveal much of her cleavage. On her hands she has cover sleeves. In her demon form, Isabella sprouts crude wicked horns and a pair of bat-like wings at her waist.

Personality
Though having a luscious appearance, Isabella hides a sinister nature. She is a sadistic demon that thinks of humans as nothing more than food or toys, taking delight in their misery and despair as she kills them during her feedings.

Background
Isabella was an immigrant from outside E-Rantel. At one point she became a business associate with Coco Doll and she received ownership of the Black Honeymooner from him, so the authorities would not suspect the criminal's involvement. All the while she has been the cause of several disappearances of employees at the brothel.

Mass for the Dead Arc
Isabella was first introduced as being a hostess to Sebas Tian for all expense paid session at her brothel provided by his co-workers from the quarry. She guided the undercover Nazarick agent to a room and introduced him to a woman named Tuare. She later had a secret meeting with the original owner of the brothel and gave her report on the management of the "goods" in the shop. When Saint Clementine and the protagonist's team are pursuing one of Coco Doll's minions, she cancels all the reservations at the shop due to the disturbance and tells Tuare and her employers to get ready to move.

Later is seen brutally torturing several of her female employees in her private dungeon while Tuare looks on in horror as she devours them one by one. The protagonist's team and Sebas Tian return to the brothel and discover the secret passageway leading to the sewers. Following it they find a hidden room there where they find Isabella and her victims. Based on the carnage and her glowing eyes the protagonist and his comrades determine that she is not human. Having no reason to hide herself anymore Isabella reveals herself as a demon. The sight of a native demon to the New World intrigues the Nazarick agents who then decide to capture her for their master. The demon tries to use Tuare as a hostage to force their cooperation but she is knocked away from the girl by Sebas Tian with a punch. Angered by the attack the demon swears to make the old man pay. Unfortunately the demon finds herself at the butler's mercy as he proceeds to pummel her with punches. Shaken at how she could be so weak before this "human" she used [Charm Person] and specially made incense on Sebas Tian. The butler seemingly under her power she gloats at the adventurers that it's over for them. Before she can command Sebas Tian to attack his allies Tuare places herself between Isabella and Sebas begging her to stop. Intrigued to her sudden boost in confidence despite ignoring all her co-workers pleas for help, Isabella sees that the girl has fallen in love with Sebas Tian.

Though she mocks at the girl's hypocrisy the girl admits her own selfishness but she is now willing to die to protect someone who cares about her. Unimpressed the demon tells Sebas to get rid of her. To her utter shock Sebas Tian merely stroke's Tuare's head commenting on her bravery revealing he was never under her power as he was a heteromorph and not a human. The demon seeing her totally outmatched attempted to escape into the sewers, with Soi in pursuit.

Later the official story told by the adventurers to the freed Tuare and the survivors was that Isabella escaped. Of course it was a fabrication to hide the fact that Isabella was captured by Soi, containing her with her slime body to be transported back to the Great Tomb of Nazarick for a proper interrogation on her unusual technique to enhance a simple spell.
