Spiritia Rosenberg

Spiritia Rosenberg (RKS001 Eins), also known as Tia for short, is the main protagonist of the doujin soft franchise Rosenkreuzstilette. She is a training instructor for RKS and the Holy Empire and is the main playable character in the first game and a supporting character in Rosenkreuzstilette Freudenstachel.

Appearance
Spiritia appears as a girl dressed in gothic lolita. She wears a white long-sleeve shirt with a black dress having white frills and black shoes. She wears a red necktie and has green hair and long blonde hair held in a ponytail with an ahoge on the front and wears a silver cross hairpin in her hair. She is one of the few characters who is not given a redesign in Rosenkreuzstilette Freudenstachel.

Personality
Spiritia is a straightforward and honest young woman who is treated with utmost respect, even by the imperial soldiers. She is also naive, and one can tell that she is a terrible swimmer due to her tendency to sink like a brick in water. Spiritia is kind, idealistic, and never gives up, knowing that giving it your all can help to change the world.

Lilli
Lilli is Spiritia's fairy friend who travels with her and supports her everywhere she goes. The two get along really well, so well that Lilli feels rather lonely without Tia there for her. Whenever Tia finds the Black Forest's Treasure, Lilli decides to borrow some of the treasure's power to help Tia.

Freudia Neuwahl
Freudia Neuwahl is Tia's childhood friend, both of who have known each other since they were children. While Freu seems rather cold to other members of RKS, she develops soft, strong feelings towards Tia, and is willing to risk her life to protect her. Tia loves Freu very much, just as much as she loves the others at RKS.

Luste Teuber
Luste Teuber sees Tia as a playmate and looks up to her so much that she likes to play games and have fun with her every time she sees her. While the two play together, Luste will often make Tia into the "bad guy."

Grolla Seyfarth
Grolla Seyfarth seems to serve as a sort of friendly rival to Spiritia. When the two cross paths in Grolla's side-game, Rosenkreuzstilette Grollschwert, Grolla mentions that she has always desired a serious match with Tia when she hears Tia declaring that she would try to protect Iris from her, and tells her to come at her with all she has. After the match is over, Grolla exchanges some words of advice that Tia can heed or cast aside however she likes: "Beware of Iris. If you don't, you'll pay a high price."

Graf Michael Sepperin
Not much is known about the relationship between Tia and Graf Michael Sepperin, other than that Tia and the others at RKS love Sepperin very much and look up to him like a father. What else is known is that both Tia and Sepperin wish to protect Iris, unaware that she was using them both for her own amusement.

Iris Sepperin
At first, Spiritia and Iris start out as friends, with Tia believing that Iris is a kind, innocent girl who is mature for her age, too. Later, when Iris shows her true colors as the mastermind behind the events of the first game, the two become enemies from that point on. Interestingly, Iris later points out that Tia, just like Iris, also reincarnated from the legendary Magus Rosenkreuz; Iris was born with his absolute power and unparallelled brains, while Tia was born with his strongest ability, the ability to tap into the strengths of others.

Abilities
Tia has many different abilities that she can use, but her main ability is the miracle power of "Seelegewehr (Soul Cannon)," the Shotgun of Souls. Using it, she can condense her mana into blasts of light magic in the form of bullets that travels above ground towards targets. The more mana she charges, the stronger her blasts will become. Tia is capable of firing these shots indefinitely without having to tap into her mana supply.

Not only is Tia able to use the abilities of her friends whenever she defeats them, but she can also summon two kinds of Silberflügel platforms; "Eins," which lets her conjure platforms that propel her higher above ground, and "Zwei," which allows her to conjure a boarding platform that propels her across long areas of hazards that can cause her to explode instantly upon contact. After getting the Black Forest's Treasure, she can also summon her fairy companion Lilli and use her to track down and attack her opponents.

Rosenkreuzstilette
Spiritia had left to train in the Black Forest for six months prior to the events of the first game, meeting and befriending a fairy named Lilli in the process. Upon returning home and arriving at the Imperial Training Hall, she was greeted by Iris only for Iris to be abducted by a grayish purple dragon that she and Lilli had seen on their way back. After the dragon left, the training hall and the Black Forest were set ablaze and Tia managed to find and rescue Lilli, who was unable to save the forest even though everyone managed to make it out alive. Afterwards, she found Freudia, who informed her that RKS was behind the attack and was plotting to sever its connection with the Holy Empire and build a new world just for Magi - all out of belief that they were the target of persecution from the Empire again. Freu implored for Tia to return to her place at RKS's side, but Tia refused, not willing to tolerate the sacrifice of innocents and knowing of the consequences that could befall her friends if she joined the rebellion anyway. After Freu left following her initial defeat at Tia's hands, Tia resolved to not only not allow her friends to get away with the attack, but also to get to the bottom of their sudden madness.
