Roseline Krackhart

Roseline Krackhart (ローズライン＝クラックハル) is a character introduced in Shinyaku Toaru Majutsu no Index. She is the aide of the current President of the United States of America, Roberto Katze, and is the one who keeps him on a tight leash. She is a central figure in Roberto's administration, especially during the Invasion of Hawaii.

Appearance
Her appearance can olny be hinted at, but she apparently wears a suit, which is only proper for a presidential aide.

Personality
She is stern, serious, and business-like, in contrast with her Presiden'ts causal and cheerful demeanor. She gives off an atmosphere that makes her suited to being a tutor. She can easily get angry, and even though she is an aide, she is unafraid of showing it too important figures such as a general or the president, let alone a reporter. Furthermore, Roberto calls her tsundere, which she doesn't take kindly to.

She is also practical and cunning as well, and would use children such as Lindy Blueshake, even to her advantage.

Background
As the Presidential aide, Roseline accompanies Roberto, virtually anywhere. She is knoweldgeable of his actions and attitutudes and prejudices towards various things. She also advises him to improve his image more. Although, maybe because of this, she has been accused of knowing every inch of his body, which pushed her to attack the reporter on national and break their nose.

Despite being merely a presidential aide, she has the power and influence to take control of American troops.

Hawaii Invasion Arc

 * Main article: Hawaii Invasion Arc

As the Presidential aide, she was most likely present during Roberto's press conference in Oahu regarding the aftermath of World War III. She wasn't apparently with him closely enough, as Roberto managed to escape with the Imperial Package, shortly thereafter.

She first appears in Hotel Firefly in the 49th floor, with an unnamed general, the Commandant of the Marine Corps, just after the disappearance of the President and trying to find him. Here, she states the suspiciousness of the people around her, most especially within the government, and concludes that it maybe the reason why Roberto left in the first place. She believes that if they can't get Roberto back, the vice-president may then be required to fill in his role, which she fears because she is also suspicious of him. With Saronia's control, Edward Torkie tried to visit Roseline and the general's room but was thwarted by Accelerator and Leivinia Birdway's intervention. She reappears in a government vehicle, responding to a secretaries's query regarding the President's father's death due to cancer, which Roseline says is untrue and that if she believed everything the President has said, his father has 80 times already.

She reappears at the height of the invasion of Hawaii by Trident, still in the government vehicle. She orders the vehicle to Pearl Harbor, however, she later discovers that it has been overwhelmed by the mercenaries as they combined the occult with typical military technology. A GREMLIN member wearing Trident's uniform tried to attack their vehicle but was saved by the arrival of Accelerator along with Leivinia. Here, they try to help the American troops turn the tide of the engagement.

Roseline later gets a call from Olay Blueshake herself, mocking her and then divulging her plans of making the United States of America into a theocracy due to the country being unprepared for the occult. After the call ended, Roseline decided to take control of 200 troops in order to find Lindy Blueshake, heir to jer mother's media empire, in Hawaii in order to gain a leverage against Olay.

With her orders, she directs an attack on the invading forces trying to attack the beaches of Kauai, securing some beaches and allowing her to start off the search for the troops to secure Lindy before Trident. The move fails as Trident arrives before her troops does, and her troops almost attacks the President, who by now, already acquired Lindy. Roseline is later stuck in the road along with a few forces after an engagement causes debris to block the road, here, Roseline receives a call from Roberto, urging her to give up on taking Lindy as a hostage against Olay. She acquiesced after Roberto suggests going after Cinesic Evers, the commander of Trident, who is also trying to obtain Lindy in order to prevent Olay's betrayal. She regroups with Roberto's forces and confronts Cinesic Evers, where they try to persuade him under the threat of extrajudicial imprisonment of him and his forces if he does not surrender. Instead, much to both Roseline and Roberto's shock, Cinesic orders all his forces to support Saronia in Napali Coast, thinking that she could defeat Kamijou Touma. However, this fails as well, as Saronia is defeated by Touma, and is later forced by Roberto to surrender.

Quotes

 * (From NT3 after being asked by a secretary regarding Roberto's father): "Of course it isn’t. He’s just bragging as always. In fact, if you take everything he says at face value, his father has died over 80 times. I was thinking of throwing a party once it breaks 100."
