Rinslet Walker

Rinslet Walker (リンスレット ウォーカー Rinsuretto Uōkā) is a main character of Black Cat. She is a thief-for-hire and an ally to the sweepers.

Appearance
Rinslet has shoulder-length lavender hair, green eyes and visible pink lips.

She wears stylish clothing and prefers to go for the tighter, shorter variety.

When in disguise as Elena Pierce, Rinslet wears a long blonde wig.

Personality
Rinslet is a flirtatious and sly woman, but she also takes her work very seriously. She is very proud of being one of the best, most resourceful thieves in the world. Rinslet will help others or even destroy what she is hired to steal if the item is dangerous to humanity. She dislikes mentioning her age. She likes jewels and shopping, but dislikes stealing anything that she cannot carry on person. Rinslet cares about Jenos Hazard, although she pretends to be put off by his flirting. In the manga, Rinslet initially has a small crush on Train Heartnet, although it hasn't become anything more than that. She constantly argues and fights with Train, but the two are actually friends. Rinslet is usually level-headed, but easily angered when provoked. She cares deeply for her comrades and would do anything to keep them out of trouble.

Eve Arc
Rinslet, disguised as Elena, runs inside Annette Pias's cafe, Cait Sith, where Train Heartnet and Sven Vollfied are eating and taking a break from their last bounty hunt. She begs Train to save her from a group of men chasing her and he begrudgingly agrees. They're easily taken care of by Train while Sven becomes suspicious of "Elena"'s behavior. He points out her hidden gun and demands to know who she is. Impressed by his perceptive nature, Rinslet waits for Train to come back before revealing her identity as an infamous thief-for-hire, having even stolen top secret information on various countries to sell to rival government officials.

Rinslet hired the men to chase her because she wanted to see the extent of Train's power. Her current job involves going after information held by Torneo Rudman, the head of a smuggling organization. She explains that she needs someone to physically overtake his security so she could get the goods. Rinslet asserts that she's safe from police scrutiny since multiple governments would have their dirty deeds revealed. Train and Sven only agree because Torneo is involved in illegal activities and also has a bounty on his head. In the end, she burns down his entire research center as she finds the information to be too disturbing and infuriating. She helps Eve pick out new clothes before parting ways with the group.

Lunafort Arc
The next time Rinslet meets Train, she is held captive by Creed Diskenth. He uses her to lure the ex-assassin out and eventually she rescues Train from his fall into the sea.

Dinosaur Arc
Later, Rinslet enlists Train's help as an escort for her next big heist: Madame Freesia's latest treasures, which are displayed every year at a party. She tells Train that it's taken her a long time and no small amount of trouble to be able to get access to the billionaire's annual soiree. The thief's hopes for a large diamond are cut short when Madame Freesia's "treasure" turns out to be an artificially created dinosaur. She leaves the chaotic aftermath unharmed yet disappointed.

Cerberus Arc
She's later interrupted during one of her escapades by Time Guardian No. VII, Jenos Hazard. She ends up being hired by Chronos to scout the location of the Apostles of the Stars. However, Rinslet is captured during this mission and is rescued by Train.

Lucifer Arc
After an encounter with Creed that transforms Train into a child, Rinslet tries to find a way to get him back to normal. She is visited by Jenos, who informs her that Beluga died and that he is here in Stock town to stop two insane Chrono Numbers from destroying the city. Rinslet learns about Tearju Lunatique, Eve's creator and relays this information to Sven.

Alliance Arc
The thief also helps Sven when he trains to improve the use of his ability to see into the future. She ends up saving the injured Sweepers during Train's final battle with Creed.

A Carefree Tomorrow
Eight months after the final battle, Rinslet meets up with Train, Sven, and Eve to catch up after so long.

Anime Plot
Rinslet,under the disguise of "Elena", hires Sven to help capture her "little sister". However, after seeing the girl, Sven deduces that Rinslet was lying. She takes off the wig and explains that the girl, Eve, is actually a highly dangerous bio-weapon. Sven saves Eve from dying at the hands of Black Cat, and she becomes a valuable friend.

Later, Rinslet is hired by the Chronos number, Jenos Hazard, to steal spirit water from Charden Flamberg. She asks for Sven's aid, in order to help him out financially. She participates in the final confrontation, but does not actually fight any Apostles. At the end, she and Jenos start dating.

Equipment and Abilities
Stealing: She is a world class thief and can steal just about anything.

Marksmanship: Rinslet owns and uses a gun but she is not as skilled at fighting as Train or Sven.

Whip: She also carries a whip with a heart shaped tip for moving quickly.

Jenos Hazard
Rinslet finds Jenos annoying due to his constant flirting with other girls, a bad habit that earns him a punch from Rinslet. She also finds it hard to believe that someone like him is an assassin. Deep down, however, she cares about him. This is shown when she expressed her concern after Cerberus fought Creed. After Jenos surprised her with the fact that he was alive, she punched him for not calling her. While Rinslet doesn't acknowledge his attempts at flirting with her, she secretly returns those feelings.

Train Heartnet
In the manga, Rinslet wanted to hire Train to help her on one of her missions. She also tested his abilities and was amazed at how he could spot her spy camera from a hundred yards away. While they were good friends, Rinslet took advantage of Train and manipulated him into doing what she wanted. The two remained friends regardless. Rinslet's profile even states that she wonders if Train is a kindred spirit. In the beginning of the anime, Rinslet does not trust Train, but as the series progressed, they became good friends, though not as close as their manga counterparts.

Eve
Rinslet tried to be a big sister to Eve, but the girl was not interested.

Sven Vollfied
In the anime, Rinslet hires Sven to help rescue her "sister" and from then on, the two become good friends. She also seemed interested in him, even searching his past. They are good friends, closer than their manga counterparts.

Sephiria Arks
When they first met, Rinslet couldn't believe that Sephiria was the number I because she seemed weak and didn't take her seriously. Later, she was offended at how Sephiria laughed at her, stating that "only an ignorant would judge people by their looks.". Rinslet was annoyed at the fact that she was being tested and even more so at every single word the Chrono number said. She made Sephiria promise to step down from her position should Rinslet succeed in her mission. Later, when she was rescued by Train, he told Rinslet that Sephiria actually manipulated her. Due to this incident, Rinslet does not like Sephiria at all.
