A list of the main characters that inhabit Seikon no Qwaser. Spoilers might be here.


Alexander Nikolaevich Her, a.k.a. "Martyr Sasha" (Voiced by Yuko Sanpei)

The Qwaser of Iron. A Siberian boy who was once training to become a member of the Adepts. However, after his sister was murdered by the Qwaser of Gold, he was recruited by an organization called Athos operating out of the Eastern Orthodox church. Presently, he is hunting down heretic Qwasers who all happen to be converging in Japan.

Ekaterina Kurae, a.k.a. "Katja" (Voiced by Aya Hirano)

The Qwaser of Copper and a sadistic little girl who also happens to be incredibly skilled at BDSM and (according to the manga) might be the reincarnation of the last Tsaritsa of Russia. Katja is a member of Athos who often walks around with a large copper puppet she calls "Anastasia" or "Mother."

Elizabeth/"Lizzy" (Voiced by Ai Shimizu)

The Qwaser of Titanium, spent most of her time training under Shinichiro Ootori and is quite devoted to him. Often mistaken for a boy at first glance. Recently (in the manga) she has joined Teresa and Athos in searching for the Theotokos of Tsaritsyn.

Tasuku Fujiomi (voiced by Kazuyuki Okitsu)

A perverted punk who happens to be a good guy (in the loosest sense of the term) thanks to the moderating influence of Mutsumi. He is the Qwaser of Neodymium, often carrying a large bracelet strapped to his wrist containing said element, he can manipulate nearly anything metallic by channeling its magnetic properties.

Tasuku is not exactly a member of Athos, as he is more under the employ of Buddhist monks than the Eastern Orthodox church. However, his interests align somewhat with Athos in wanting to stop the Adepts from getting the power of the Theotokos of Tsaritsyn.


Referred to as "Hell's Dairy Cow" by Teresa, she is a master tactician and trainer for the Qwasers of Athos.

12 Adepts

12 Adepts

Ayana Minase (Voiced by Ayahi Takagaki)

Qwaser of Magnesium, one of the Adepts, pretends to be Mafuyu and Tomo's friend to find the Theotokos of Tsaritsyn.

Croa a.k.a. "Gas Chamber"

The Qwaser of Chlorine. A Croatian Adept who "cleansed" several ethnic Serbians in the old Yugoslavia, including those of Teresa's old church.

Aoi/Yuu Kuchiba, a.k.a. "Double Face"

Another member of the Adepts who happens to be the Qwaser of Oxygen. Yuu became a homicidal maniac after the training his church put him through as a kid, and his sister Aoi tried to support him until she was forcibly turned into a "Maria" for his use. Long story short, Aoi's latent powers awoke and she killed her captors, but one of those present was her brother Yuu, and the shock of the event somehow caused Aoi's mind to recreate Yuu as a split personality in her own body.

Despite supposedly being Killed Off for Real (twice), Kuchiba appears to have been resurrected a third time (in the manga, at least) to carry out Tanner's plan.

Eva Silver, a.k.a. "The Queen of Living Silver"

The Qwaser of Mercury who happens to be a brutal sadist and another one of the Adepts. In reality, she is actually Eva Anna Paula Braun, the ex-wife of Adolf Hitler who managed to stay alive this long by creating young clones of herself that she could kill and absorb whenever she needed to regenerate her own body.

Joshua Phrygianos

A member of the Adepts who is stuck with the unfortunate mastery of the element Roentgenium, an element with a half-life of about four seconds that does not exist in nature on Earth. As a result, he tries to prove to his fellow Adepts that he isn't useless, but most of the time even the protagonists just feel sorry for him.

Qwaser of Lead (real name unknown)

Prefers sniping his targets from long distances, shaping lead into crude bullets without metallic jackets.

Friedrich Tanner

An enigmatic blonde-haired gentleman who appears to be manipulating both the Adepts and Athos. Though not exactly a Qwaser, he does appear to have some sort of magic powers with tarot cards he carries that allows him to do everything from Mind Control to summoning members of the Adepts to do his bidding. He seeks the Theotokos so that he can destabilize Europe and resurrect the Holy Roman Empire with Germany at its head.

The Qwaser of Gold

The leader of the Adepts whose true face has never been seen. His only real appearance in the story has been through possessing Tomo using a "golden nail" implanted somewhere in her chest that constantly drains her Soma and strengthens the Qwaser himself. He was the one who killed Sasha's older sister Olja, and apparently used Sasha's anger at him to launch an entire Evil Plan spanning years just so he could later use a large-breasted Japanese schoolgirl to gain the Blade of Maria through a special Faberge Egg and somehow use its power to change the world in his image.

There are hints in the anime and the manga that this Qwaser is actually a Catholic cardinal named Gregori.

Jita Phrygianos, a.k.a. "Black Diamond"

The Qwaser of Carbon and the younger sister of Joshua, though she often looks down on him. She distrusts Tomo at first but slowly opens up to her after she steps in to help break up a fight between herself and Georg. In the anime, she immediately makes a move on Tomo's body after the first scene.

Jita often attacks using ultra-thin diamond strings that can cut through practically anything.

Georg Tanner

The Qwaser of Cobalt and brother of Friedrich. He is a much more narcissistic and arrogant man than his brother, but he shares his goal in using the power of the Theotokos to resurrect the Holy Roman Empire. He constantly spends time cleaning the cobalt ornament attached to his hand, but said ornament allows him to focus gamma radiation into laser beams that can be used against his opponents.

Milk (a.k.a. "Whisper Bomb")

Not much is known about Milk other than the fact that she is a little pink-haired girl who never speaks and is always shown wearing a gas mask. In the manga, cartoonish little bombs can be seen floating around her. She is the Qwaser of Hydrogen.

Wang Chen

A Chinese man who is the Qwaser of Silicon. The manga portrays him as a scientist under the supposedly defunct Parcelsus, and is working on an experiment that involves trapping girls inside a Lotus Eater Machine.


Mafuyu Oribe (Voiced by Ayumi Fujimura)

The female lead of the story who often walks around with a kendo shin'ai, she is Sasha's current partner and self-proclaimed protector of Tomo. Many Qwasers seek her out early in the story, thinking she knows where the Theotokos of Tsaritsyn is hidden. Mafuyu contains one half of the Blade of Maria after accidentally interrupting the ceremony.

Tomo Yamanobe (Voiced by Aki Toyosaki)

The daughter of Yuudai Yamanobe with the most gigantic breasts of the whole cast, she contains one-half of the Blade of Maria after being manipulated by the Qwaser of Gold. She is currently being held by the Adepts after being captured by Tanner.

Teresa Beria (Voiced by Minori Chihara)

A nun who tends to the church at St. Mikhailov Academy, also Sasha's original Soma donor.

Hana Katsuragi (Voiced by Yoko Hikasa)

A bully who continuously torments Mafuyu and Tomo along with Miyuri, but after Katja's appearance she became absolutely devoted to her instead.

  • Aw, Look -- They Really Do Love Each Other: Despite Hana complaining sometimes about Katja being too cruel to her, she was willing to risk her life and throw herself into the fire that Katja couldn't get out of because of Oxygen's attack to save her.
  • Corruption by a Minor: In short, Hana is an implied lesbian pedophile (the only person we see her exercising these urges with mostly revolves around Katja, so what extent this true is uncertain). Regardless, Katja manages to make her succumb to her suppressed predations and she becomes her Maria, though this ironically becomes a good thing, as Hana's former Jerkass exterior fades to reveal a surprisingly large heart of gold, ironically making this trope a good thing.
  • Curtains Match the Window
  • Faux Action Girl: Though in her defense, she's not good at it and knows it.
  • Happiness in Slavery/Too Kinky to Torture
  • Jerkass -> Jerk with a Heart of Gold
    • Notably in the second season where she claims, it's wrong to leave a classmate behind. Now look back at her first appearance in Season 1.
  • Kids Are Cruel
  • Lolicon: Katja's introductory chapter in the manga implies that she's had pedophilic inclinations before meeting Katja, stating that she had a secret she could never share with anyone. In a way, her Sex Slave status to Katja gives her a relatively safe outlet for her desire.
  • Noblewoman's Laugh: In the first episode of season II, she even Lampshades that she feel like Miyuri.
  • Playing Against Type: Hard to believe she was voiced by Yoko Hikasa.
  • Too Kinky to Torture: Katja and a villian in Season 2 find out, much to their dismay, there is no way in hell to degrade this woman, as all it does is turn her on.

Mutsumi Sendou

Sasha's former "Maria" back in Russia, she came to Japan with Tasuku.

The Qwaser of Sodium who wishes to search for the Theotokos on his own, despite offers of help from both Athos and the Adepts. Formerly the Number Two of the Qwaser of Gold.

Miyuri Tsujido (Voiced by Ayako Kawasumi)

Daughter of the Dean of St. Mikhailov Academy who enjoys lording her status over Mafuyu (and most of the class, by extension). She has an ongoing rivalry with Mafuyu and even lets Hana and Katja stay at her place (in the manga) just to spite her.

  • Hair Decorations: She has two ribbons in her hair.
  • Les Yay -- With Lizzy (in the first season anime). Gains a few levels in this with a few of the other girls by the second anime.
  • Muggle: Oddly played with the anime. She still seems amazingly ignorant as to the full extent of what's going on despite multiple viewings of things that should have shattered the masquerade, but at the same time, especially after her mellowing she's seems to have some vague idea of the weirdness around her.
  • Noblewoman's Laugh - ironically done when she's posing as a masked vigilante, but played straight a few times before and after showing her self-sacrificing True Colors.
  • Rich Bitch: Though she turns somewhat Spoiled Sweet over time.
