Introduction

Nasiens「ナシエンス」 is a young herbalist Percival meets at Echo Gorge, later appointed as a Holy Knight of Liones and member of the Percival Platoon. She is later revealed to be the long lost child of King and Diane, swapped out for Mertyl years ago. She was also chosen by the Sacred Tree as King's successor and the Future Fourth Fairy Ruler.

Appearance[]

Nasiens is a teenager with short brown hair with bangs, amber eyes, fair skin and thin eyebrows. Because she doesn’t yet have a defined gender, Nasiens has an androgynous appearance, although at first people assumed she was male.

She wears a dark blue suit under a white coat and a white hat. Before leaving Liones, Nasiens is given a new outfit consisting of a green suit under a white jacket with pockets for test tubes, a wider hat, and shoes with long socks.

After the time-skip, Nasiens let her hair grow to chin length and her bangs became shorter, giving them a more feminine appearance. Later, she began to develop more feminine traits, such as the increase in the size of their breasts and the development of other parts of her body.

Several of her siblings have noted Nasiens' striking resemblance to King and Diane, more than any of their kids.

Personality[]

Nasiens initially appears as a calm and composed teenager, occasionally intimidating, and rarely reveals their true emotions. However, with Percival, Donny, and Sin, she developed enough trust to express their feelings openly. Despite this, Nasiens still harbors some secrets, as Anghalhad noticed when they sensed Nasiens was concealing something.

Nasiens has a deep interest and curiosity in plants, aspiring to become an herbalist like their adoptive grandfather, Ordo. She is thrilled by new discoveries and delights in exploring their surroundings. Nasiens also demonstrates considerable intelligence regarding plants and their properties.

Overall, Nasiens is a calm, serious, intelligent, insightful and polite individual, much like their father, King. Like him, she can be highly sentimental and shy, struggling to express her true feelings due to years of isolation. For instance, when she tried to tell Percival he was her first friend, she shyly called him her "guinea pig" instead. Nasiens also inherited traits from her mother, Diane, including her friendly, gentle, and serene nature, as well as her deep care for her friends.

Nasiens' adoptive sister, Dolores, noted their "good heart," evident when Nasiens healed Echo Gorge despite facing hatred and insults from the fairies. Similarly, when King offered to help awaken Percival after two years of failed attempts, Nasiens was more concerned about whether her father should prioritize helping Mertyl.

History[]

Nasiens is King and Diane's first child. However, shortly after her birth, a fairy kidnapped Nasiens and swapped her with a newborn Mertyl. Later, she was abandoned in Echo Gorge, where Ordo found and adopted her. Nasiens grew up studying to become an apothecary like her grandfather, Ordo, until he mysteriously disappeared. Soon after, a strange disease began draining the life force of Echo Gorge's plants and animals.

Nasiens began conducting experiments to develop a cure for Echo Gorge. However, some of her failed concoctions had unintended side effects, causing the animals and plants to become monstrous and violent. As a result, the local fairies mistakenly believed Nasiens was attempting to destroy Echo Gorge.

Abilities/Equipment[]

Raised in Echo Gorge and mentored by Ordo, Nasiens gained extensive knowledge of medicines and herbs, mastering her identification and synthesis to create original concoctions, which became her primary area of expertise. Despite this focus, Nasiens has proven herself a skilled combatant, adept at dual-wielding Henbane and Belladonna with ease, further enhanced by her magical abilities.

As King and Diane's child, Nasiens is a half-Fairy, half-Giant, with her Fairy genes appearing much stronger than her Giant genes appearance-like. It is possible that living outside the Fairy Realm stunted the development of Nasiens' inherited abilities. However, Nasiens' condition and health improved noticeably after residing in the Fairy Realm, and her innate Fairy and Giant abilities were awakened.

Nasiens has demonstrated the ability to influence the Spirit Spear Chastiefol, capable of halting its charge and redirecting it, a trait inherited by those chosen by the Sacred Tree, particularly future leaders of the Fairy Clan.

Abilities[]

  • Mix Venom調毒ミクスベノムMikusu Benomu」: This power enables Nasiens to ingest any kind of poison and "teach" its composition to her body, letting them create their own mix.[6]
  • Poison Immunity: Due to being Half-Fairy and due to the nature of Mix Venom, Nasiens seems naturally resistant to poisons, toxins and diseases, which notably allows her to withstand the environment of the Fairy Realm without having to suffer dizziness or asthma.
  • Levitation: Although at first Nasiens doesn’t seem to have the Fairies's ability to fly, Nasiens later awakened it while channeling the powers of the Sacred Tree against Worreldane. Nasiens retained this power after the encounter, but is still learning to utilize it fully.
  • Connection to Nature: Nasiens appears to be able to "sense" the medicinal properties of plants and minerals. Sixtus indicated that fairies do not have the ability to sense minerals and privately thought that this might be a manifestation of Nasiens' Giant heritage.[7]

Combined Techniques[]

  • Quartet Attack - Slash Squall四重奏攻撃カルテットアタック - 剣撃の雨スラッシュ・スコールKarutetto Atakku - Surasshu Sukōru」: Nasiens, Anghalhad, Percival and Donny each attack a single opponent with their swords.[8]

Equipment[]

Nasiens dual-wields the dagger Henbane麻痺毒ヒヨスHiyosu」 and the shortsword Belladonna睡眠毒ベラドンナBeradonna」.[9] She also use needles that they throws at enemies to apply her poisons.

  • Bipolar Gloves対極の手袋バイポラーグローブBaiporā Gurōbu」: A pair of magical gloves created by Dubs. They allows Nasiens to freely switch between intense heat (up to 150ºC) or intense cold (down to -150ºC), also changing the nature of her poisons by manipulating its temperature.[10]
  • Spirit Spear Pendant: Nasiens obtained from King a pendant made from a piece of the Spirit Spear Chastiefol, which contains the power of the Sacred Tree and is able to transform in response to Nasiens' wishes. However, being just a small piece, it is limited to just two forms.

Relationships[]

Four Knights of the Apocalypse[]

Percival[]

Ever since Percival saved her grandfather, Nasiens has harbored romantic feelings for him, although she prefers to hide it. Nasiens has referred to Percival as her hero and personal guinea pig, as an attempt to hide her true feelings. Nasiens has put herself in the line of fire to protect Percival on multiple occasions and has been watching over his body for two years attempting to awaken him. Her love for Percival is what ultimately defines her gender as feminine.

Although Percival's naivety initially kept his feelings for Nasiens unclear, he finally confess that he harbors an equal romantic attraction for both Nasiens and Anghalhad. Therefore, he suggests that the three of them can have a polygamous relationship. Nasiens accepts this and is then able to tell Percival that she loves him for the first time with the two almost sharing a kiss.

Donny[]

Nasiens seems to consider Donny a good friend, although she isn’t always comfortable with some of his playful and sometimes irresponsible attitudes.

Anghalhad[]

Nasiens respects Anghalhad a lot calling her by her full name rather than her nickname. Nasiens also appears to trust Anghalhad and is not afraid to open up to her, despite being quite shy when doing so, such as when she questions whether she is in love with Percival or if she is actually a boy.

When Nasiens discovers that Anghalhad also has romantic feelings for Percival she feels no anger or resentment towards her and still considers her a dear friend. Although said in a friendly manner Anghalhad views the two as rivals since they are both in love with Percival. Nasiens does not see it that way and prefers to continue having a friendly relationship with her. When Percival suggests that the three of them become a couple, Nasiens says that the idea makes her very happy since she respects Anghalhad just as much as loves Percival.

Family[]

Ordo[]

Nasiens loves her adoptive grandfather very much and considers him an important member of her family, even risking her life to save him from Talisker's control.

Dolores[]

Nasiens loves her adopted sister very much and considers her an important member of their family. She also cares a lot about Dolores, as shown when she was worried after she was hit by Ordo's attack. She also doesn’t tolerate insults towards her sister, as she was angered by Donny calling her a "zombie".

King[]

At first, Nasiens is very polite and respectful towards King because he is the King of the Fairies and is guarding Percival's body in his kingdom. However, after King offered her the Drug of Yore, rather than giving it to Mertyl, not knowing that King had already done so, Nasiens currently views King with considerable distaste. Due to King's lack of clarity with his motives, Nasiens considers him "hard-headed" and his actions to be in poor taste. Nasiens has shown the capacity to put her feelings aside and quickly came to lend King her power when battling Worreldane. Despite not expressing it verbally, Nasiens considers King as part of her family.[11] Before leaving the Fairy Realm Nasiens openly called King her father.

Diane[]

Nasiens is very polite and respectful towards Diane because she is the Queen of the Giants and is guarding Percival's body in the Fairy Kingdom together with King. Despite not expressing it verbally, Nasiens considers Diane as part of her family.[11] Before leaving the Fairy Realm Nasiens openly called Diane her mother.

Tioreh[]

Tioreh calls her new-found sibling "Nassie" and loves her very much. She spent the two years Nasiens was in the Fairy Realm following her around and was very curious about her sibling overall, in part to confirm her suspicions about her relationship. Tioreh was the one to reveal to Nasiens that she wasn’t human. Nasiens appears to trust Tioreh and has little issues opening up to her whenever her sibling questions her directly. Despite not expressing it verbally, Nasiens considers Tioreh as part of her family.[11] Nasiens promised to return to visit her and the rest of her siblings.

Mertyl[]

Nasiens was very worried about Mertyl's health after finding out his breathing is affected by the Fairy Realm. Nasiens also tells her family that Mertyl is her real older brother. Despite not expressing it verbally, Nasiens considers him as part of her family.[11]

Sixtus[]

Despite not expressing it verbally, Nasiens considers Sixtus as part of her family.[11]

Belte[]

Despite not expressing it verbally, Nasiens considers Belte as part of her family.[11]

Zana[]

Despite not expressing it verbally, Nasiens considers Zana as part of her family.[11]

Zilian[]

Despite not expressing it verbally, Nasiens considers Zilian as part of her family.[11]

Phao[]

Despite not expressing it verbally, Nasiens considers Phao as part of her family.[11]

Trivia[]

  • Nasiens is probably inspired by Nascien, a Knight of the Round Table in Arthurian legends who turned to hermitage after witnessing the Holy Grail.
  • Nasiens shares her English voice actor with Gloxinia.
  • As Fairy/Giant Hybrid, Nasiens gives off a scent of Osmanthus.[12]
  • Whenever Nasiens gets excited, she has a tendency to bite their lip till it bleeds.
  • Like Diane, Nasiens has a habit of hiding her face when she was embarrassed, but instead of covering her face with her hair, Nasiens covers it with her hat.
