He naturally possesses a relaxed and manipulative demeanor, something that infuriates virtually everyone that he come into contact with.

* **Marie**

Mercurius is deeply in love with Marie, falling for her at first sight. The events of Dies Irae were all set up by him so that she could kill him and take the throne.

#### Longinus Dreizehn Orden

Aside from Reinhard, every member of the LDO has varying levels of hate towards Mercurius and were eager to take their frustrations out on Ren.

Reinhard Heydrich
His Apoptosis and sworn friend.

* Rusalka Schwagerin

Over a century before the formation of the LDO, Mercurius saved Rusalka from imprisonment and taught her sorcery.

* Ren Fuji

In reality, Mercurius does not especially care about Ren, seeing him mainly as a tool to fuel Marie's growth.

## Story

### Before Dies Irae

Mercurius originates from the world of Zoar.

While details are unknown, he was decribed by Kouha as a "bug" in The Morning Star system, becoming the Mercurial Snake. He was able to reach the Throne by taking advantage of the time paradox that Nerose Satanael created at the end of Paradise Lost, using Sequere Naturam to atomize the Hegemony God in a single hit.

After attaining the throne, Mercurius's law originated the world of Omega Ewigkeit, in which time looped endlessly. It is unknown what his original desire was, though it is implied that he wished to know all things. His law also allowed the concept of "possibility" to enter the throne, creating the multiverse.

He eventually created the Die Ewigkeit style of sorcery along with several others.

In 1775, he, through his sensory Alessandro di Cagliostro, ventured to a remote German village in the late 18th century and freed an imprisoned Anna Maria Schwagerin from captivity, slaughtering her guards. He then taught her several styles of sorcery before disappearing.

Growing bored with the eternal recurrence, Mercurius began searching for a way to die. It was during that search, that he, as Cagliostro, found himself at Marie's Twilight Beach. Instantly falling in love with Marie, he decided that she was the person most fit to kill him and take the throne. However, as she was a Transcendence god, not a hegemony god, she could not take the Throne for herself, so Mercurius began crafting a plan to both kill himself and change Marie's desire to transform her into a Hegemony god.

#### Die Morgendammerung

Through another sensory, Karl Ernst Krafft, Mercurius successfully predicted an assassination attempt on Adolf Hitler as well as several other high ranking officials, leading him to be has taken into the Gestapo Headquarters for questioning. This act gained him the attention of Reinhard Heydrich, his apoptosis. The two would become friends and Mercurius eventually convinced Reinhard to fulfill his desire of spreading his "love" through out the entire world. Mercurius then went on in assisting Reinhard and Heinrich Himmler in the formation of the Longinus Dreizehn Orden, though he and Reinhard would evntually go on to highjack the organization from Himmler's control.

During the battle to determine the final member of the Obsidian Round Table, Mercurius took an interest in two of the participants, Lotus Reichhart and Michael Wittman. When Lotus was defeated by Michael, Mercurius divided his soul, fusing half of it into Michael, transforming him into Machina, and combining the other half with his own blood to create his Holy Relic, Zarathustra Übermensch, which he left in the hands of ODESSA.

### Interview with Kaziklu Bey

Mercurius met with Wilhelm Ehrenburg and Claudia Jerusalem at the Paderborner Dom, a Roman Catholic Cathadrel in Paderborn, Germany. There, he informed Wilhelm about the summons to Wewelsburg Castle.

He later leaves the LDO and disappears some point before the start of Dies Irae.

### Dies Irae

#### Kasumi Route

Mercurius remains entirely absense through out the entire route. Only appeared in the epilogue, commenting Ren temporal victory.

#### Kei Route

Mercurius grants to Shirou Yusa Rusalka's Holy Relic. After that, he participates to the last fight alongside Reinhard against Ren, Kei and Shirou, but no one dies.

#### Marie Route

During Ren and Reinhard's final battle, they manage to create a singluarity and open a path to Marie's twilight beach. There, Mercurius interrupts their fight, explaining his intentions to them before allowing them to proceed.

As their fight concludes, Mercurius asks Marie, now a Hegemony God, to embrace him and in doing so take his life, but Marie refuses. As there is still the possibility, however slim, that Marie will embrace and kill him some day, Mercurius's law doesn't activate and he, along with Ren and Reinhard act as Marie's guardians as she takes the throne and emanates her world.

#### Rea Route

During Ren's initial fight with the Three Commanders, Mercurius allows Ren to access the full strength of the mercury blood in his veins, allowing Ren to access Eine Faust Finale.

At the end of the route, Mercurius properly fulfills his role as an antagonist. During Ren and Reinhard's final battle, the two manage to create a singularity and reach the throne, where Mercurius awaits.

In the first ending, Mercurius duels with his Apoptosis. Reinhard's powerful legion clashes with the soul of the entire universe of Mercurius, ultimately result in a tide. Mercurius who was about to reset the universe again was confronted by Marie, who finally give him the death he desires. During the final goodbye, Mercurius and Reinhard have a ball with Marie and Rea, contemplating the possibility of Ren joining the fight.

In the Three Colors' battle, all three proceed to battle over the throne. The fight is so intense, that the throne itself is destroyed by Mercurius's Disce Libens.

At the end of the battle, Mercurius declares Ren to be the victor and dies in Marie's arms, as he has desired for so long. However, even after his death, Mercurius's law forces the world to repeat on last time, restoring the throne, allowing Marie to take it.

### Before Kajiri Kamui Kagura

8000 years before the start of the game, Mercurius, along with Reinhard and Marie, is slaughtered by Hajun.

#### Alternate Timeline

In one possible timeline, Mercurius, Reinhard, Ren, and Marie all manage to defeat Hajun, but with the later 3 dying during the battle. As the only Hegemony God remaining, Mecurius then takes up the throne again, causing his law to reverse time back to before the events of Dies Irae. He then takes steps to prevent Hajun from coming into existence.

### Dies Irae Pantheon

**Excerpt from Dies Irae Pantheon site translated**
***The fourth God who overthrew Myoujou and took the Throne, his Law locked every living being within an endlessly looping world."***

"***Bringing the concept of life after death into the world, extending his grasp over multiple time-axis and parallel worlds,he could undoubtedly be called a renovator of the Throne universe."***
