Eleanor Ran

She was one of the apprentices of Ragishss, and was known as one of the Four Witches of Kathtom, specializing in illusion, possession, and sword-mastery. Cruel and lewd due to the ring's power, but is actually very shy and kind when the curse removed.

Personality and Appearance
She lives with a strong sense of duty and responsibility. She's a very old fashioned girl who believes in having sex only with the one you marry.

Under the spell of the Ring of Feel, she was turned into a sadistic, cruel and even lewd person. However, her true personality is the meekest, most responsible person out of the four. She is kind to others, and strict to herself.

After coming to herself, she feels guilty of what she has done. Ever since then, she has been working hard for the city of Kathtom.

She does however have a bad habit of keeping everything to herself, and think negatively of situation. In Kichikuoh, this trait of her makes her suicidal when she is forced into Rance's harem.

She has a long red hair and usually wears formal suits, she probably took that habit after she became a mayor but she's still seen in formal clothes when adventuring.

Abilities
She is a capable spellblader, which is a very rare talent in The Continent, being adept with illusion magic, as well as the sword. In Rance 02 she was capable of throwing people into illusions and made them lose control of their senses with just crossing eyes, which forced Bird to close his eyes when fighting her. However, said strategy left him vulnerable since he was oblivious to her skill with the sword and she could cut off his arm in an instant.

While her magic and swordplay are nothing particularly impressive she's definitely profficient enough with both to be considered a considerable threat for any fighter with experience on his back. She has a pretty good cap of 30 and her current level is 15, since she weakened after becoming a mayor and attending mostly office paperwork.

Rance 2
One of the Four Witches of Kathtom, she appears in her own maze, which somehow resembles human's internal organs, like heart, intestine, and so on. Her task is to abduct more young girls from town and turn them into slaves till they are ready to be "used" by Masou Shizuka, though soon foiled by Sill and Bard's teamwork.

She is the one responsible for cutting Bard's left arm.

In the later events, she got defeated by Rance in a fair sword-fight, mainly due to her eye's inability to possess Rance at all. Following her defeat and "rescue", the possession of her ring is lifted, and she becomes her usual timid self.

To repent what she and her comrades ever done to Kathtom, Ran becomes an employee in the office to cover the reconstruction of town by borrowing money from Leazas.

In the last chapter of story, Ran partakes in the battle against Ragishss who regained the ring's full powers, though beaten and is forced to retreat along with the rest of group.

Rance 3
She appears in the ending credit. It looks like she has some serious accident.

Rance 4
Rance sees her through a magical device in the West Tower. She was monolouging to herself about the Kathom budget deficit. She was slightly aware of the presense of Rance but assumed it was her imagination.

Kichikuou Rance
She appears as a mayor. Eventually joins with Shizuka, Maria, Milli, and Mill after Rance conquered Custard Town.

Rance Quest
Part of Rance's party in Rance Quest.

At this time the town Kathtom's reconstruction was completed and its business is booming more than before, and the youngest of the Four Witches of Kathtom, Mill, already grown up and can take care of herself, making Elenoa lose her sence of purpose and even mentioned that she want to commit suicide to pay for her crimes when she was under the ring's spell. Rance know this and gave her a new purpose for living: to hate him and protect Shizuka, Maria, and Mill from him.
