Mjur Farmenas

Mjurran (ミュウラン) the Ring Finger, was one of Clayman's "Five Fingers" and was acting as one of his spies.

Appearance
Normally, Mjurran would disguise herself to look like a regular human. But she is actually a Majin and her true form, which has a third eye on her forehead, various tattoos on her body, monstrous claws on her hands and fur growing on some parts of her body, reflects that.

Personality
Mjurran is a very responsible person, she is a careful woman who tries to plan things ahead in her favor.

She had no experience in love. Though Mjurran ends up falling in love with Youm, a human who accepted her true self; Mjurran noted Youm to be the only one to have won her heart in the long time she has been alive. Although she is a slut, and Youm is selfish to be overcome by lust, they are still alive for some reason. Youm chose someone he just met in lust, over the person who saved his life countless times, and made him a champion.

Background
Mjurran was once a witch, living in The Great Jura Forest. Persecuted by others, she had fled from there three hundred years ago—quietly researching her magic, interacting with no human or Majin. Eventually she was nearing the end of her lifespan.

Facing death, Mjurran had some slight sense of regret due to not having made satisfactory advance in her research, nor having a successor and wondered if her life had been wasted.

At this moment of weakness, she was visited by the Demon Lord Clayman. He had been a Demon Lord for about three hundred years at the time and was negotiating with the more well-known monsters and Majin in the area and getting rid of those who refused to do so. He was looking to quickly building up his subordinate forces, which led him to Mjurran.

Seeking her magic, he offered: "Let me grant you eternal time and a young body that will never age. In exchange, I ask you to swear your allegiance to me."

Mjurran accepted it, which she came to regret in retrospect, as although she did indeed gain eternal youth, but in exchange lost her freedom. Due to her inexperience in human relations, she realized too late that she was swindled.

The moment she made the oath, a cursed seal, the "Marionette Heart" was carved into her heart. It was one of Clayman's most secret of curses, allowing him to use a mix of expensive magical media with the magicules of the target to turn the receiver into a Majin.

It was successful, and Mjurran became a "marionette," unable to defy the will of Clayman.

Mjurran was not satisfied with her situation and tried to find a way out of her slavery, but then Clayman explained her that even if she got rid of the "Marionette Heart," she'd revert to her aged form and soon die of old age. In addition, Clayman was too powerful for her to defeat him.

So Mjurran had not choice but to continue serving Clayman.

Demon Lord Attack Arc
Mjurran was assigned by Clayman to secretly investigate the Jura Tempest Federation, but she could not get too close as it might draw the attention of Demon Lord Milim Nava, who had spotted her, so she chose to observe from afar for the time being.

Demon Lord Awakening Arc
Since Mjurran could tell Clayman's interest in herself was dwindling, and since Milim ended up leaving, she decided on a more hands-on approach of getting into the Champion Youm's entourage. To do that, she went to the Kingdom of Falmuth where Youm comes from and usually does his work and gained an adventurer license there. She then requested to join Youm's party but was instead looked down upon. After defeating Youm, Rommel, and Jagi, They welcomed her into the party and became their advisor.

After joining Youm's group, she became responsible for giving tactical advice to the party and providing in-the-field guidance on working together to fend off monsters and magical attacks. She openly revealed that she is a Wizard and gave her teachings to Rommel, Jagi, and everyone else in the party that was at least somewhat familiar with magic.

As a military adviser, she also had the vital role of casting the deciding vote on the party's actions, which however also increased her responsibilities and work further.

Days passed on as Mjurran firmed up her position on Youm's team and taking part in their work through which Mjurran continuously felt more pleasant about her situation.

Later, the group headed back to Tempest.

Back in Tempest, Grucius had underestimated her and was defeated making him fall in love for her. When Gobta saw this, he had asked her to help him and Youm in defeating Hakurou. Mjurran reluctantly accepted her participation in the mock battle, but Hakurou ended up defeating all of them on his own.

Time passed, and Mjurran ended up falling in love with Youm, but Clayman anticipated that and used her newfound feelings to blackmail Mjurran into taking up "one last mission" for him, which is the deployment of an Anti-Magic Area over the whole of Rimuru City at a predetermined moment.

In her situation, Mjurran using that Great Magic that blocks the use of magic, would have the effect of immediately exposing herself as a Majin and it would make her a target of resentment for Tempest, while also sealing up her own means to defend herself. Clayman hoped that this would provoke them into killing Mjurran, giving him a Casus Belli to later excuse military action against Tempest, in case Tempest ends up winning the confrontation with Falmuth.

Mjurran, preparing to cast the Anti-Magic Area, turned into her Majin form, but before she could follow Clayman's order, Grucius and Youm caught her red-handed. She is asked to stop by both, but due to Youm not detesting or fearing her due to her appearance as a Majin and instead him even claiming that he loves her, it emboldened her resolve to sacrifice herself to not give Clayman any reason to get rid of Youm and so she decided to follow Clayman's order to the end.

Afterwards, Rimuru, who had just returned, ordered Mjurran, alongside Youm and Grucius, to be put into house arrest.

Rimuru, a short while later, came to her place of detainment together with Benimaru to interrogate her. Mjurran revealed everything, as she did as ordered by Clayman and no longer cared about her own life. After Rimuru decided he heard enough, he proclaimed that Mjurran's punishment would be her death. Youm and Grucius tried to interfere but could not hope to put up a resistance against Rimuru and Benimaru. Before her punishment was enacted she told Youm that she also loves him and that he "shouldn't be tricked by another woman like her in the future."

Following that, Rimuru approached Mjurran and then used Gluttony to phase through her body and clothes to directly crush her "Marionette Heart," and replacing it with a similar "Pseudo Heart." Rimuru then explained that Clayman's Marionette Heart was like a wiretapping device that allowed Clayman to listen in on their conversation and that the Pseudo Heart does not have a "paired" counterpart, nor the wiretap function, so Mjurran had essentially become free without losing the benefit of eternal youth. Mjurran then accepted Youm's declaration of love as she "didn't mind being tied down for the short duration of a human life."

After Rimuru explained his plans of having Youm take over control over the Kingdom of Falmuth, Mjurran decided to help Youm become a king and guide the nation as to never oppose Rimuru ever again.
