Grolla Seyfarth

Grolla Seyfarth (RKS006 Sechs) is a heroine from Rosenkreuzstilette who is a supporting character in many RKS titles and the main protagonist of Rosenkreuzstilette Grollschwert. She is the current heiress to the Demon Sword Grollschwert, which was once wielded by her grandfather and mentor, Raimund Seyfarth.

Appearance
Grolla's appearance is that of a young woman with long purple hair and eyes. She wears a black short-sleeved body suit with silver armor worn over it and a brown cloth around her waist, and wears brown boots. She wears a white headband around her forehead with a cross on its front and wields a large broadsword called Grollschwert. In Freudenstachel, when she takes up her grandfather's own Grollschwert, she gains some new bandages wrapped around her arms, stained with blood.

Personality
Grolla is a calm and collected young woman and a tomboyish knight who talks on a feudal tongue, treats her colleagues with respect, and is willing to protect them at any cost. Nevertheless, should she be angered in any way, Grolla will stop at nothing to exact her revenge. Born with the spirit of a warrior, she prefers to fight first and ask questions later. Grolla is also shown to be arrogant, having high pride in her abilities and insulting her opponents whenever she gets the chance (save for her colleagues when she fights them, of course).

Spiritia Rosenberg
In Rosenkreuzstilette Grollschwert, Grolla sees Spiritia Rosenberg as a sort of friendly rival, having always desired a serious match with her. When Tia tries to stop her from hurting Iris Sepperin, Grolla uses that moment as a perfect opportunity for said match. After the match is over, she trades some helpful advice with Tia warning her to beware of Iris or else she will pay a high price.

Sichte Meister
Sichte is Grolla's close friend and mistress, whom she treats with respect, calling her by the name of Lady Sichte. Grolla is willing to protect her mistress no matter what, and will strike down anyone who dares mess with her in any way.

Trauare Wrede
Trauare Wrede sees Grolla as a friendly rival in the same fashion that Grolla herself sees Tia as one in Grollschwert. Trau is often curious about her and competes with Grolla to see whether the Chaos Spear Leviathan or the Demon Sword Grollschwert is the greater weapon.

Iris Sepperin
Iris becomes Grolla's primary adversary in Rosenkreuzstilette Grollschwert. When Grolla stumbles upon Iris' murder of a priest and overhears her plan to have RKS fight against the Empire for her entertainment, she sets off to get back at Iris for humiliating her and for betraying the organization. If there's someone who's trying to protect Iris, Grolla will fight them in order to reason with them and/or just get them out of her way of getting her revenge against her.

Rosenkreuzstilette
Her role in the original Rosenkreuzstilette is among the many who have been commanded by Graf Michael Sepperin to kill Spiritia, who has been branded as a traitor to RKS. Following her orders, Grolla called Tia the "Empire's lapdog" and challenged her to battle. Grolla was of course defeated by Tia, and Sichte then entered. The dialogue depends on whether or not Sichte was defeated before her. Regardless, Grolla stood down and allowed Tia to proceed closer to Graf Sepperin's castle.

Trivia

 * Her name comes from the German word "Groll", meaning "Grudge" or "ill will". Her surname comes from Andreas Seyfarth, a German board game designer best known for his 2002 game, Puerto Rico.
 * She is the only one out of Spiritia's friends in RKS (other than Graf Sepperin) who does not refer to Tia by her short nickname.
 * When she calls out to the Cross Wall to show her its worst in Grollschwert, her line, "There is nothing my blade cannot cut!", alludes to a line spoken by Shiki Ryougi in the visual novel Kara no Kyoukai.
 * Grolla possesses several allusions and references to Zero from Mega Man X. In Grollschwert, Grolla stood up against the organization that she was formally a part of for the sake of stopping a rebellion launched by RKS as orchestrated by Iris, similarly to Zero when he stood against Repliforce when they were manipulated by Sigma into fighting to create a world for Reploids. She also ended up fighting those who are close to her, among them Sichte and her grandfather, Raimund, as she went to exact her revenge against Iris. Zero follows on a similar case; Zero fought against Iris, his potential lover, after killing her brother, the Colonel, in Mega Man X4. Afterwards, Zero later fought against his closest friend, Mega Man X, near the end of Mega Man X5.
 * In addition, her playstyle is also based on Zero in said series as well as Mega Man Zero.
 * Grolla actually takes twice as much damage in Grollschwert as Tia does in the original game.
 * In Grollschwert, Grolla reveals herself to be one of the most profane characters in Rosenkreuzstilette. In fact, she is shown to be one of three characters to use words of profanity, the other two being Lilli and Zorne Sepperin.
 * A screenshot from the Rosenkreuzstilette Freudenstachel April Fool's site depicts her fighting against Freudia Neuwahl in the same area that Spiritia (or Grolla herself) fought against her grandfather at in the original game and wielding her grandfather's Grollschwert, which she still does in the current versions of Freudenstachel. The notable difference was the glowing red eyes, which were never used in the trial versions of Freudenstachel's release after the April Fool's screenshots. This change was probably a result of either the Grollschwert or Raimund possessing her during the fight.
