Sylphiette is the childhood friend and wife of Rudeus Greyrat and the mother of Lucy Greyrat and Sieghardt Saladin Greyrat.


Formerly: short green hair, pretty tomboy like appearance, elf ear and skinny.

After Mana Calamity: short white hair, due to Mana Calamity, slender body, elf ears, track and field girl appearance, she also wore a thick pair of sunglasses as part of her bodyguard duties.

After her marriage with Rudeus, she began to let her hair grow longer and wear more feminine clothing. Due to her elfen heritage, her body ages slower in comparison to humans.


When around Rudeus, she has a cutesy personality. She is reliable and quite knowledgeable in a lot of area which in turn make it easier for Rudeus to ask her for advice.

Her loyalty lies with Rudeus first and in the family, she is known as the 'housewife'. She is intellectual.

Fitts: She is silent, boyish, serious, and act like a cold knight.


When she was a child she was always bullied for her being a mix and having emerald green hair. The bullies would throw mud balls or rocks at her sometimes, and kick her too, until Rudeus saved her and they became friends.

After the Teleport Incident, she was teleported to the Royal Palace where she saved Princess Ariel, 3rd in line to the throne of Asura Kingdom. Afterwards she became her friend and protected her against countless assassination attempts under the alias "Fitts" (she was disguised as well). Later she enrolled into «Ranoa Magic Academy» where she was considered a genius for her ability of using voiceless incantations.

Her Fire Magic is weaker than her other magic, because she is afraid of fire unconsciously. The cause of her fear was a burn she experienced when she was 3 years old.

Sylphiette is first seen being bullied for her emerald green hair and getting chased and getting hit by mud balls thrown at her by the village children, Rudeus saw the event and decided to step in to stop the bullies.

Mushoku Tensei Novel Volume 7 - Youth Period - School Entry Chapter

She is reunited with Rudeus at the Ranoa Magic Academy, however he did not recognize her because she was disguised as a boy and her hair had turned white as a result of overusing her magic during the Mana Calamity. Then, she was disguised as Fitts-senpai and the bodyguard of Ariel Anemoi Asura.

She is known as the [Mystery], the one who was feared between Ariel, Luke and herself. It was said that she had once single-handedly managed a handful of delinquents that posed a threat against Ariel, which caused people to stay away from her.

In the volume, she had been the one to test Rudeus to see if he was truly eligible as a [Special Student] of the Ranoa Magic Academy. She had later been shocked by how strong and potent he had become, even though he had only displayed the skill [Rock Bullet].

She is often seen in the library and had many meet-ups with Rudeus there. At the Magic Academy, like Rudeus, she had made use of it to find the reasons behind the Metastasis Event, even aiding Rudeus to find out the cause of it. In fact, she even remembers the titles of the books that she has read, showing her intellectual side.

For the most part of the chapter, she is seen trying to make Rudeus remember who she was, as she still held a liking for him. In the end, she helps Rudeus cure his impotency and she becomes his wife.

Before the happenings of the entry into the Magic Academy, she had been teleported to the Asura Kingdom and found herself falling from the sky. In a desperate attempt to soften the blow, she casted magic one after another which caused a mana strain, causing her hair to go white. She then coincidentally lands into the place where Ariel was nearly assassinated by a rampaging magical creature and saves her by throwing out a spell.

The incident earns her recognition and she is later promoted to become Ariel's guard, escorting and protecting Ariel until the end of the Asura Kingdom Arc and Ghyslaine Dedorudia takes over her role.
