Introduction

Nasiens「ナシエンス」 is a mysterious teenager Percival meets at Echo Gorge, later appointed as a Holy Knight of Liones and member of the Percival Platoon. They are later revealed to be the long lost child of King and Diane swapped out for Mertyl years ago as a Changeling by an unknown fairy.

Appearance[]

Nasiens' first outfit

Nasiens is a teenager with short light brown hair and yellow eyes and at first was mostly mistaken for male.

They wear a black full body suit under a white coat and a white hat. Before leaving Liones, Nasiens receives a new outfit composed of a a green suit under a white jacket with pockets for test tubes, a wider hat, and shoes with long stockings.

As stated by Mertyl, Nasiens resembles King and Diane. Tioreh noted the resemblance between them was very “close”.

Personality[]

Nasiens seems to be a calm and serene teen, who can also be scary at times, and rarely makes their true feelings known. Although with Percival, Donny and Sin, they have managed to have enough trust in all of them to show them their emotions without hiding anything. However, Nasiens still keeps some secrets, as when Anghalhad perceived that they were hiding something.

Nasiens has a great interest in plants, wanting to be a herbalist like their adoptive grandfather Ordo was. They get very excited when making new discoveries, liking to experiment with everything around them.

Nasiens can be very sentimental, but being isolated for so many years, they does not know how to show it; an example of this would be when they could not find the words to tell Percival that they considered him their first friend, and ended up saying "guinea pig".

Nasiens’ adopted sister Dolores noted that they have a “good heart”. When King offered help to awaken Percival after two years of failed attempts, Nasiens was more concerned with their father “helping” Mertyl.

History[]

Nasiens was kidnapped by a fairy as a baby, swapped for a baby Mertyl; was abandoned in Echo Gorge and was found and adopted by Ordo. Nasiens grew up studying to be an apothecary like their grandfather, Ordo, until one day Ordo disappeared and soon after, a strange disease began to eat the life force of the plants and animals of Echo Gorge.

Nasiens started conducting experiments to create a cure for Echo Gorge, and as a side effect of some of their failed drugs, the animals and plants became monstrous and violent. This led to the local fairies to mistakenly believe that Nasiens was trying to destroy Echo Gorge.

Abilities/Equipment[]

As the first biological child of King and Diane, Nasciens is a Fairy/Giant hybrid in whom the fairy genes seem stronger than the giant genes, just like Sixtus, Belte and Tioreh.

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 their body, letting them create their own mix.[4]
  • 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」: Anghalhad, Nasiens, Percival and Donny each attack a single opponent with their swords. [5]
  • Telepathy: Due to their true origins as a Half-Fairy, Nasiens seems capable of perceiving the thoughts of Fairies who seek to communicate with them, as was the case with King.
  • Poison Immunity: Due to their true origins as a Half-Fairy, Nasiens seems naturally immune to poisons, toxins and diseases, which notably allows them to withstand the environment of the Fairy King's Forest without having to suffer dizziness or asthma.

Weapons[]

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」.[6]

They also use needles that they throws at enemies to apply their poisons.

Relationships[]

Four Knights of the Apocalypse[]

Percival[]

Same as Anghalhad, Nasiens seems to have romantic feelings for Percival.

King[]

Nasiens currently views King with much suspicion. Due to King’s lack of clarity with his motives Nasiens considers him “thick-headed”. King deeply cares about Nasiens and watched him closely while Nasiens attempted to awaken Percival and felt pain watching Nasiens’ constant disappointment in his failed efforts. He was devastated when Nasiens declined his offer of help and his firstborn scolded him for his behavior.

Tioreh

Tioreh calls her new-found sibling ‘Nassie’ and loves them very much. She spent the two years Nasiens was in the Fairy Realm following them around and was very curious about their sibling overall, in part to confirm her suspicions about their relationship. Tioreh was the one to reveal to Nasiens that they were at least part-Fairy. Nasiens appears to trust Tioreh and has little issues opening up to her whenever their sibling questions them directly.

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 their English voice actor with Gloxinia.
