Setsuna Kusakabe (草壁 刹那, Kusakabe Setsuna) is a supporting character in the Seraph of the End: Vampire Reign manga series. She is a Sergeant of the Japanese Imperial Demon Army and the leader of her squad in the Moon Demon Company.

She also appears in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen light novel series.

AppearanceEdit

Setsuna has dark brown hair that falls to her waist and reddish brown eyes. Her bangs sometimes cover her left eye.

Her JIDA consists of a long-sleeved black tailcoat with light green details and two rows of gold buttons on the front and shoulder epaulettes. Her collar is unbuttoned and her sleeves are rolled up to her elbows. Rather than the standard white gloves, she wears black fingerless gloves along with an armband on her left arm, and a white web belt with a gold waist-plate. Instead of the standard uniform skirt, Setsuna wears similarly colored shorts. She also wears dark gray thigh-high socks and knee-high black boots.

PersonalityEdit

Setsuna is a serious and mature person but only became like that when her parents died during the apocalypse. She is very observant and thinks in a rational matter most of the time. She has a very strong sense of justice.

Since she belongs to the Order of the Imperial Moon, she is loyal to Guren and holds great disdain for the Hīragi Family (save for Shinoa and Shinya) due to the harsh treatment her family received from for being members of the Imperial Moon. Her loyalty in Guren is shaken after Nagoya as Setsuna feels that she can never truly trust him if he's being possessed by his demon.

HistoryEdit

Setsuna was born in 2002 to a retainer house that serves the Ichinoses.

After the apocalypse, her parents died, and she and her brother joined the Japanese Imperial Demon Army and were trained to be soldiers. She worked as part of Shibuya's Military Police until joining the Vampire Annihilation Force's Moon Demon Company when she was thirteen. Sometime later, she was promoted to Sergeant.

She later proved herself to be capable handling a weapon of the Black Demon Series and eventually became the leader of her squad.

Story: Guren Ichinose: Catastrophe at SixteenEdit

Book 6Edit

Setsuna and her family are present at Sakae Ichinose’s funeral where she later meets Makoto Narumi and Shūsaku Iwasaki.

Story: Vampire ReignEdit

Shinjuku ArcEdit

She and her squad arrive at the battlefield in Shinjuku to help Guren and Shinoa squads.

Post-Shinjuku ArcEdit

She visits Yu in the hospital to check in on him as she was worried about what happened to him in Shinjuku. She is later called and interviewed by Lieutenant General Kureto Hīragi about what happened in Shinjuku and to try to get her to join him and become his subordinate. Setsuna refuses because she is loyal to Guren.

Nagoya ArcEdit

Setsuna Squad arrives on time at the Ebina Rest Stop. When Shinoa Squad faces off against Guren, Mito, and Shinya, Setsuna watches the battle intently. She is impressed when Yu manages to hold his own against Guren. Even so, Guren's team defeats them easily.

Setsuna Squad is paired up with another squad to exterminate vampire nobles in Nagoya. Their main objective is to kill a 16th Progenitor which they succeed at.

Their team regroups at the meeting spot. Sergeant Aiko Aihara arrives with only seven surviving team members; although they killed their target, they suffered eight casualties. Guren arrives with his squad. Guren orders Shinoa Squad, Narumi Squad, and Setsuna Squad to join his team to hunt down Thirteenth Progenitor Crowley Eusford, Seventeenth Progenitor Chess Belle, and Seventeenth Progenitor Horn Skuld and to rescue hostages. Guren orders Aiko to wait half an hour for any more survivors and send them to Nagoya Airport.

Once they reach Nagoya City Hall, Guren looks at the hostages being used through a telescope and knows that they are being used as bait to lure them. Guren says that their top priority is to maintain their numbers, letting no one die. Their second priority is to free the hostages and lastly, getting the hostages out alive. Guren then says that they need to keep the vampires occupied in Aichi Prefecture for as long as they can so they can buy enough time for the main forces in Shibuya to get prepared.

After Crowley catches Gekkōin, Guren and his squad discuss what to do. After careful planning, Guren decides that his squad will take his squad to attack Crowley while the Shinoa, Setsuna, and Narumi Squads free the hostages. He gives them five minutes to rescue as many hostages as they can and act as a proper diversion for the main force in Shinjuku. As soon as the five minutes are up everyone has orders to retreat to the Nagoya Airport immediately.

Setsuna Squad reappears after Kimizuki captures Yu, having already rescued the hostages. Shinoa Squad joins up with them and many injured soldiers. They flee, and Rika Inoue reports seeing a single vampire straight ahead. Shinya says they can handle one noble and orders them to keep pushing forward. The Moon Demon Company attacks Mikaela Hyakuya.

After Shinoa Squad protects and allows Mika to escape, Shinya orders them all to move now. Common vampire soldiers jump down from the helicopters, surprising them in the midst of their drama.

As the Moon Demon Company rendezvous at Nagoya Airport, where they planned to use a transport chopper in order to escape from the vampires they find that there is no chopper. Shinya states this mission was devised by Kureto, and the Moon Demon Company decides to abandon its mission and rescue Guren instead.

Kureto Hīragi arrives and orders Aoi Sangū to sacrifice the surviving Moon Demon Company soldiers for their experiment. Her chains pierce many soldiers, including Rika Inoue and Shūsaku Iwasaki, and hang their corpses in the air. All the members of Setsuna Squad manage to stay alive as like Shinoa, Setsuna orders her squad to hold onto their weapons.

Yu, Mika, Shinoa Squad, Setsuna Squad, and Narumi fight for their lives as human and vampire armies wage war around them. As they escape, they are shocked to run into Guren. Guren greets Yu and then attacks him, but Mika blocks the attack.

Kureto notes that four of the surviving soldiers are Guren's soldiers with the black demons. Chains erupt out of one of the trucks. Mika, Yu, and Setsuna block them. Kureto says the black demon wielders have matured and muses having them for himself but says that their owner will dispose of them.

The experiment continues, and the demon Abaddon is successfully manifested. Yu then awakens in his seraph mode. He defeats the demon and later stabs himself through the chest with his cursed gear.

As Shinoa Squad make their escape from Nagoya Airport, Setsuna Squad prevents JIDA soldiers from getting to them.

Post-Nagoya ArcEdit

Three months later, Setsuna is imprisoned within Shinjuku's Japanese Imperial Demon Army HQ.

Guren visits her and in anger for what happened in Nagoya, almost becomes fully possessed and threatens to kill him. He tells her that he has a mission for her.

Osaka ArcEdit

Powers and AbilitiesEdit

Natural AbilitiesEdit

Setsuna like all people who wield Cursed Gear, has heightened strength and regeneration abilities.

She is shown to be a skilled swordswoman having been trained since she was six. She is also quite skilled at martial arts which she also started when she was six. She is also knowledgeable about Cursed Gear, Demons, and vampires as well as army politics.

Setsuna is a very capable leader as she was chosen to be the leader of her team.

Magic and SpellsEdit

  • Talismans: Setsuna is skilled in using talismans, often cloaking her presence with them, sealing up the movements of her enemies, and making barriers with them. She can also implement a talisman on her sword to augment the weapon's cursed power and ability. Her incantation speed is said to be very fast.

Cursed Gear Edit

  • Genyagami 「幻夜神, lit. Phantom Night God 」: A manifestation-type demon weapon of the Black Demon Series. It takes the form of a black ōdachi. It is a medium-range weapon. Like Shinoa Hīragi, she can call upon her demon to fully use its power to attack opponents.
    • Shadow Manipulation: A special ability using Genyagami that allows Setsuna to manipulate her shadow to attack or defend. She can attack anything that has a shadow and can protect herself with a black space that is made from shadow. The ability also allows her to create tendrils from the shadow to strike or bind enemies.

ExperimentationEdit

  • Drugging Up : Like other soldiers in the JIDA, Setsuna takes a supplement to increase her synchronicity with her demon to 150% for 15 minutes. After that time is up, this synchronicity drops to zero. There are numerous unpleasant side-effects, and officers only resort to this as necessary.

TriviaEdit
