"You ran away from your destiny once...
Why return to the Hollow Night now?"

Seth (セト) is an assassin of the Night Blade and the wielder of the Eliminator who is currently working for an unknown client. He is the archrival of Hyde.

He is one of the twelve characters introduced in the original version of UNDER NIGHT IN-BIRTH.

Background[]

The Assassin who Wanders the Night

UNDER NIGHT IN-BIRTH

A young boy feared from those who know him as the "Assassin". He appears before certain power users, challenging them to duels, but no one knows why. Or, for that matter, who he is. However, the moment he heard the name, "Princess of the Night Blade", his attitude changed. His emotionless face was no longer so. Since that day, he wanders the town, searching for the princess, not on anyone's orders.[3]

UNDER NIGHT IN-BIRTH II [Sys:Celes]

Seth is a young warrior of the Night Blade who has earned the title of Assassin.

In order to save Princess Linne, he defeated Hilda with his legendary weapon, the Blade of Judgment. Some time later, Linne's older brother Kuon appears. He and his sibling bear the Power of Sealing--a curse left behind by the Night Blade of ages past. As a member of the modern-day Night Blade, Seth has had one purpose since childhood: to relieve the siblings of their duties as keepers of the curse.

Seth has already received Linne's Power of Sealing; in order to recover the remaining one from Kuon, Seth sets out into the Night...

Information[]

Seth is a 1st year student in the same high-school as Hyde. To some he's mainly known as the "Assassin" (暗殺者).

Appearance[]

Seth is a teenager with grey eyes and short black hair, although about one-fourth of it is white on the front of his left side. He wears a high-collared double-breasted black coat with a tattered end sticking out behind his right leg, blue pants and black shoes.

Personality[]

Seth is an extremely serious individual and never shows any emotion beyond stoicism. Although his cold attitude may come off as insensitive, he is greatly burdened by the mistakes of his ancestor and feels that if he fulfills Linne's wish for death, he can redeem his family name and free himself of the past. In Yuzuriha's story, her optimistic way of life despite her family's history briefly causes Seth to question his path and his individuality.

Seth does attend school and has above average grades. He's bad at communicating and tries to avoid contact with his classmates in order to keep them from "getting involved"[4]. His presence is rarely noted in the classroom and Seth is pretty much free to come and go as he pleases. He lives alone and is skilled with all the housework as he has been helping his family since he was young[4].

Story[]

Years ago people within the Night Blade started to think that people should be allowed to do whatever they want to do with their abilities. This resulted a rebellion and internal fighting within the Night Blade - Seth's ancestor was one of these rebels.

Seth has been trying to fix the mistakes Night Blade made in the past, which has led him to lead an aimless existence cleaning up after himself and killing off whatever is within the confines of both his power and his contract. He's aiming to claim the Indulgence of Insulation and remove the "curse" placed on Linne and Kuon using that sword. This would naturally put him at conflict with Hyde due to the weapon being in his possession.

Abilities[]

Seth's ability is the "EXS of Excavation" (穿鎖のEXS): Kerykeion (ケーリュケイオン). It allows him to create "chains" that pierce the opponent's flow of EXS and temporary seal their abilities[4]. It is an extremely rare ability. It's effect could directly be applied to a weapon, but Seth unfortunately lacks the skill to harness his ability in this way. Instead, Seth developed his whole fighting style around the way in which it's easiest for him to use his ability[4]. That's how he ended up with his current style of creating small balls that shoot the "chains" in the midst of Seth's high-speed sword attacks.

Seth was entrusted with the Twin Swords: Eliminator (双剣・エリミネーター) from Kuon as a part of his deal with Chaos. The other name of the blades is the Indulgence of Elimination (封滅の免罪符). Their relation to Hyde's Insulator haven't been explained yet, but they are told to have to the opposite power to that of Insulator. Before getting the Indulgence Weapon, Seth is told to have had expertise in a normal pair of daggers during his time of assassinating.

So far, Seth has displayed abilities in moving within the shadows along with basic stealth skills, and is able control a small level of darkness in the form of either creating a mote that fires a stunning arrow or an afterimage. Most of the time he focuses on his agility to be able to cleanly cut down his target with finesse and speed.

Composer Commentary[]

Monochrome Memory
Seth's basic themes are "solitude" and "grief".

I create the tunes for UNI with high importance on the song intro. But Seth's intro was created with guitar riffs from the start. That intro riff lead me all the way to the refrain during the creation. But talking of the distribution of feelings, instead of going all-out with the refrain, I put some weight to express the sorrowfulness in the second verse. If the refrain is too complex, the song would lose its momentum.

Instruments are simple drums, bass, guitar, piano and synthesizer. Without putting too much emphasis on it and making the song too sparkling. [5]

Mutual Situation
"Combine Hyde's refrain melody with Seth's intro riffs and you'll get something this cool!!?" is how I started up with this. I don't usually take stuff like this into calculations when creating theme songs for each character.

To express how the close combat takes them to their limits, I explained to sho-san that "This is where Hyde is attacking!" and "Here's Seth attacks", then he just ad-libbed the guitar parts for the first verse.

While mastering the expression of a close match, in the refrain their movements synchronize and become entangled as they fight like dancing. That's the kind of song this is. It ended up pretty much like I had first imagined it. [6]

Monochrome Memory
セトは「孤独」と「哀愁」を基本テーマにしています。

UNI楽曲は特にイントロを重要視して制作していますが、このセトもまずイントロありきでリフを思いつきました。そのイントロリフを元にサビまで連想で制作してますが、気持ちの配分でいくとサビよりもBメロの哀愁感に重きを置いてます。サビを複雑にすると曲の勢いがなくなるので。

楽器はシンプルにドラム・ベース・ギター・ピアノで、シンセは主張させずあまりキラキラさせないようにしました。

Mutual Situation
ハイドのサビメロとセトのイントロリフを重ねたらすごくカッコよくない!?と思いついてしまったのです。各テーマBGMをこういう風に使う想定で作ったとかではないです。

ギリギリの接戦を表現したくてAメロはshoさんに「ここはハイド攻め」「ここはセト攻め」みたいな感じでアドリブで弾いていただきました。

そんな混戦を極めながらサビではその戦いは舞の如くシンクロし絡み合う。そんな曲です。最初の思いつきがほぼイメージ通りに作れました。

Introduction Text[]

He wanders. Bound by the will and governing of an ancient family, but his emotions tremor.
The promise he made with a young girl shackles him in rusty chains he strives to sever. The
Night becomes a labyrinth, impeding his progress. Will he ever find the beacon he seeks?

He wanders -- Bound by the will and governing of an ancient family, but his emotions tremor.
The promise he made with a young girl shackles him, in rusty chains he strives to sever. The
Night becomes a labyrinth, impeding his progress. Will he ever find the beacon he seeks?

He strays. The whole family's rule and onself's will. It sways in the interval.
The promise with a girl ties. The least recently rusty chain hauled in and stopped.
The promise with a boy severs it. The grey wedge dug in compensation.
It turns into the labyrinth which confuses him a deep night. Is the lamplight to greet visible?

He had gone astray. The statute of the family and his own will. He sways in between.
The promise with the girl connects. Drawing the old rusty chain.
The promise with the boy is broken. The dull grey wedge penetrates for the compensation.
Deep nights turn into the labyrinth that deludes him. Will he see the light of acceptance.

Creation & Development[]

Seth's design originally started from scrapped designs of Hyde. The producer Narita was originally against the addition of Seth as he felt like the game already had enough gloomy and dark characters. Yoshihara personally liked Seth's design and was determined to get him into the game. He polished the design and promised the producer that after Seth he'd draw as many cheerful characters as Narita wanted[7].

Yoshihara was careful to add colors like blue and silver that made Seth seem more like Hyde's rival. The key of Seth's design was to visualize "Assassin" and "Night Blade". His design has a lot of sharpness. In the mook interview, Yoshihara reflects that he wanted to brush-up the details of Seth's bottom half more as it felt a bit too simple[8].

Trivia[]

  • The term Kerykeion is an ancient winged scepter with two serpents coiling around the shaft, used as a symbol of medical profession and modeled on Hermes' staff.
  • Seth's name is written in katakana as "Seto" instead of the typical "Sesu". It is possibly as a reference to Set/Seth, the god of the desert, storms, disorder and violence in the Egyptian mythology.
  • The futon he uses to wrap Linne with in his Arcade Mode is apparently the one he sleeps in.
  • Seth's favorite food is fishes boiled in soy sauce, otherwise known as nitsuke (煮付け).
