**Ren Fujii** (藤井 蓮, *Fujii Ren*) is the main protagonist of Dies Irae. He also known as ***Principle of the Transcended Man**Zarathustra Ubermensch***,(超越する人の理)ツァラトゥストラ・ユーヴァーメンシュ, an Ahnenerbe of Mercurius and his substitute.

## Appearance

Ren had shoulder length blue hair and matching eyes. He is noted to resemble both Mercurius and Lotus. When he starts using Die Ewigkeit, he gain's Mercurius symbol, a caduceus, in each eye.

## Personality

Ren is considered a recluse by many in his school, quiet and enjoying staying with him. He is characteristically crude and straightforward in his dialogues, and even when he tries to be polite, he usually gives raw answers to questions, especially when angry.

Ren is sarcastic, perceptive and intelligent, often having fun at Kasumi's expense.

Ren is also slightly perverted, and although this side of him is rarely shown, he is not ashamed to show it when he has the opportunity. However, the most striking thing about Ren is his desire for serenity and routine; His greatest desire is to have a repetitive, but safe and good life, a desire that is embodied in his Briah "I want to live this moment forever".

Every since witnessing Shirou kill Kasumi's father Ren has had a strong aversion to blades of any kind. However, he seemingly gets over this after meeting Marie.

He is a tsundere, acting somewhat coldly to those he is close to, despite actually caring deeply for them. He is very doting upon Marie.

## Story

### Before Dies Irae

Ren Fujii was created by Karl Ernst Krafft, also known as Mercurius, as his substitute, who would fill seat XIII of the Obsidian Round Table in his place during the battle at the Eastern Shambhala, Suwahara City, which would see the resurrection of Reinhard Heydrich and the erasure of the world of Eternal Recurrence, which the Golden Beast plans to wash away with his own world. As his substitute, Zarathustra (Ren's magic name and identification within the LDO) would serve (capitalizing in the hatred the rest of the Beast's Fangs feel against Mercurius) as the opponent they'd have to face once they arrived to the city, in order to open the eight Swastika scattered over the city, as mere bloodshed won't serve to complete the Transmutation of Gold as needed. Therefore, true battles would be needed and, as long as a majority of the Swastika open due to battling and not one sided massacres, the Longinus Dreizehn Orden's goals will be fulfilled. This role exists alongside another; to be Reinhard's promised opponent, who would truly push him to his limits, so he could fulfill his wish of fighting with his full strength against an adversary that can withstand it, and that opponent that will take the shape of his sworn friend substitute, upon reaching the peak of its powers.

Ren's birth took place at the exact time the Obsidian Round Table's seats were filled. He's the other half of the being that came to be known as Machina, using Lotus Reichhart's soul as the basis for his consciousness, and later fused with Mercurius' blood. This way, not only did Ren have the potential to achieve Godhood, but he also effectively became Mercurius' shadow, his very own Ahnenerbe.

    Despite being created so many years prior to the story's start, it still took long for Ren to gain awareness, and more so to reach a point in which he could serve his purpose. For that reason, he was entrusted to a descendant of members of ODESSA in Japan, organization that helped Nazis to escape persecution. The man, named Kouzou Ayase, claimed that Ren's parents had died in an accident and, given they were his dearest friends, he was tasked to be his adoptive father. The infant Ren, despite harboring doubts about having parents at all, believed Mr Ayase. He got into the Ayase family, made of the man, his wife and their daughter, Kasumi, as if he were one of their own. It is during these peaceful years with the Ayase family that he met his best friend, Shirou Yusa.

However, the bliss of a happy family life did not last. One day, in 1995 (back when Ren and Shirou were only 6 years old), Shirou murdered Mr. Ayase, with Ren helping in covering the crime up. Though Mr. Ayase died from being stabbed in the neck, courtesy of Shirou, they managed to hide the corpse for a time and, after that, mask his death as a complete accident, making it seems as if he had fallen upon one of the blades he kept at home. Being children, of course, no one would think they were murderers. Furthermore, the discovery of a torture room in the man's basement further cemented him as not being a completely innocent man. Kasumi and her mother remained, of course, unaware of Ren and Shirou's involvement.

Ren, Kasumi and Shirou moved together to Suwahara City two years prior to the start of the main story. They lived in the same apartment block, Ren's apartment being in between Shirou and Kasumi's. Apparently, Kasumi's mom wouldn't let her move if they didn't live in the same building. Shirou didn't waste a second a brought down the wall between his and Ren's apartment using a hammer, so he could access it quickly. However, in 2006, two months before the story begins, Ren and Shirou have a brutal fistfight in Tsukinosawa High's rooftop. Shirou, claiming that he is tired of their boring, daily life, and wants to play with all variables available to him, plans to tell Kasumi about the truth of her father's murder. Ren, unwilling to let his best friend ruin his daily life, begins with the fight. In the aftermath, they are found lying in the rooftop by their upperclassman, Rea Himuro, whom the group had struck a solid friendship with since they arrived in Suwahara City, who calls an ambulance to take them both to the hospital, as both their bodies have suffered many injuries.

### Dies Irae

#### Common Route

##### Chapter 1: L'enfant de la Punition

Two months after his fight with Shirou, Ren's recovery in the hospital has ended, and thus, he's ready to continue with his normal life once again. After getting everything sorted out, Ren leaves the hospital and heads straight for home before Kasumi has a chance to arrive. However, and to Ren's surprise, he bumps into Kasumi on his way home, who had skipped school just to pick Ren up. After some bickering, Kasumi offers Ren to go on a date, a plan which she is quick to inform her friend is not hers, but Himuro's. Their upperclassman handed Kasumi two tickets for the blade exposition in Suwahara City's Museum, so that's what their date is going to be.

Upon arriving at the Museum, Ren is not comfortable at all, primarily because he has an irrational dislike of blades (probably due to the incident of Mr Ayase's death), specially when they are weapons, as the majority of objects in the exposition are. Just when they are going to leave, Ren sees himself attracted to an object not in the exposition, by a mysterious voice. The object in question is a guillotine, an instrument used in executions during the French Revolution. Being repulsed by it, Ren and Kasumi decide to leave, but not before Ren sees the specter of a girl in front of the guillotine.

Back at their apartment block (Shirou doesn't live near them anymore, as he disappeared shortly after getting to the hospital) Ren rest after having a panic attack at the Museum.

That night, he sees Twilight Beach and that same girl in his dream. After hearing her singing, a vision of the guillotine execution replaced the previous scenery, where he is the one who got beheaded.

At the same time, Kasumi begins her killing spree under the influence of Mercurius, acting as an "executioner" of the guillotine to gathers souls on Ren's behalf.

##### Chapter 2: Xenophobia

Every night, Ren would have the same dream about the guillotine over and over again. Along with the ever-presence of the murder, he cannot deny his suspicion about the connection between the two.

On their way back from school, Ren and Kasumi meet with a priest Valeria Trifa, who lost his way to Suwahara Church, the place that is also the home of his upperclassman, Rea Himuro. They decided to lead him to his destination. After some chat with Riza Brenner and others at the church, Trifa asked Ren with strange suggestions; such as telling him to leave the town or mentioning his parents, those who were never in his memory and never truly existed.

Worried about Kasumi, Ren subconsciously sleepwalking until found himself at the park in the middle of the night. Besides him is a severed body of a woman who was killed by Kasumi. Before he could make any sense of the situation, he is assaulted by two LDO members, Wilhelm Ehrenburg and Rusalka Schwagerin. Suspect him for his position as Karl's substitute, they tried to interrogate him about his supposed Holy Relic. Failed, Wilhelm shifted his focus to entertainment. Leaving no choice but to fight with the indomitable Apostle, Ren was easily defeated. Before Wilhelm's killing blow can be delivered, it was stopped by Kei Sakurai. Bey and Malleus decided to retreat, healing Ren before leaving.

On the next day, Kei and Rusulka enter Tsukinosawa school under the disguise of a transfer student.

##### Chapter 3: End of the Nightmare

Ren confront Rusalka and asked her about the basic information of the situation, which voluntary complied.

Later that evening, he and Kasumi went on a tour around the town. Their conversation was interrupted, as Ren passed out, switching into a vision of Kasumi, who resume her killing. Upon waking up, he ran into Kei, who spilled the situation to him. Determined to save Kasumi, Ren confronted her. Getting through her invisible blade, he managed to seize control over the guillotine, ultimately freed her from the role of an executioner and all the memory of her murders.

##### Chapter 4: ODESSA

By gaining the guillotine, Ren is filled with a desire for killing and decapitation. Tried his best to restrain himself, he is confronted by Kei, who promptly agreed to teach him about the usage of Holy Relic in order for him to be her worthy prey.

They meet at the school during the nighttime, Kei taught Ren about the stages of Ewigkeit, forcing him to use his Assiah to break free from Sakurai's grip. Their session got interrupted by Rot Spinne, who has been spying on them all along.

That night, Ren had a conversation with Marie for the first time, though not much was gain asides from her name and the place of Twilight Beach.

In order to prevent Kasumi from getting involved again, Ren told her he's dating Kei to avoid suspicion. On his way back, he spots Rot Spinne among the crowd. He departed from Kasumi to track down Spinne. After his brief meeting with Trifa along the way, Ren receives a phone call from Spinne, tricking Ren that he had captured Kasumi. Ren found him at the Suwahara Park, where Rot struck him a deal; to join forcing and prevent Reinhard from descending onto the universe. Apparently, Spinne has a terrible fear for The Golden Beast and his vassals. Refuse, of course, Ren has his first proper fight with an LDO member.

During the battle, Ren manages to make a connection with Maire and thus activates his Yetzirah for the first time. Margueritte-Bois de Justice. He severe Spinne's Holy Relic and gravely injured the spider. Leaving the scene, Spinne is still alive. Although he is later finished off by Kristoff, opening the second Swastika.

Back at home, he embraces Kasumi, who is unharmed before falling asleep.

##### Chapter 5: Holiday

On the next morning, naked Marie materializes next to his bed. After clearing confusion with Kasumi, the three go on a tour of the city. In the end, they meet with Eri Honjou, who invited them to meet with Shirou.

##### Chapter 6: Lord of the Dead

Ren and Marie go to reunite with Shirou at The Bottomless Pit. Knowing about The Obsidian Roundtable, he wants to get involved for the thrill. To prove the danger, Ren cut Shirou pistol with ease before leaving.

At Suwahara Tower, Kei and Wilhelm await him. Kei wanting to simply escort Ren to Kristoff, refused, the fight broke out. Putting into 2-1 battle, Ren is in huge disadvantages, that is before Shriou comes to his aid. The two split with Shirou fighting against Wilhelm and Ren duel with Sakurai.

Taking their fight to the bridge, Ren got the upper hand over Sakurai. However, their fight is interrupted by Valeria Trifa. Facing Divine Vessel himself, Ren is put to the ground. At that moment, the brand of the LDO members bleeds and Reinhard Heidrich himself appears as a shadow in front of Ren.

Later, Ren wakes up chained in a dungeon below the church where he is brought to the Obsidian Round Table's chamber by Trifa. There, he speaks with Reinhard and after goading him, the leader of the L.D.O returns Marie to Ren's side.

Valeria Trifa is surpised that Ren returns unscathed. Promising to let them go, Ren and Marie exit the church and he discovers they have been missing for a day and it's Monday.

At the end of Marie's Route Ren battles Reinhard, and their fight creates a singularity which leads them to the Marie's Twilight Beach where Mercurius awaits. The Fourth Heaven interuppts their fight, taking the oppurtunity to explain his intentions before allowing the two to continue.

Ren manages to defeat Reinhard with the help of Rea who used her connection as the womb to unbirth Reinhard's legion, giving Ren a final chance to decapitate finally the Gold.

### Before Kajiri Kamui Kagura

After the events of Marie's Route, Ren, who had ascended to godhood during his battle with Reinhard lived on in the world she had created up until 8000 years before the events of Kajiri Kamui Kagura, when Hajun ascended to the throne and slaughtered Marie, Reinhard and Mercurius. Ren only escaped due to Hajun never noticing his existence. At which time, Ren used his law to stop Hajun's world from coming into effect and to preserve Marie's world. He was given the name Tenma Yato and created his legion, the Yatsukahagi, which protected the land of Edo and the remains of Marie.

##### Eine Faust Overture

**Eine Faust Overture** is Ren's Briah. It is a Gudou-type Briah that accelerates Ren's time when activated, giving him an effect similar to superhuman speed to the outsider.

##### Eine Faust Scherzo

**Eine Faust Scherzo** is acquired during Kei's Route. His desire being, "I don't want the dead to live", It allows Ren to kill the living dead, such as member's of the LDO. It is powerful enough to threaten the existence of Gladshiem and its undead denizens.

At the end of Kei route,Ren emanates his Hadou craving based on Eine Faust Scherzo,by doing this,he killed Reinhard and Mercurius,taking the latter's throne before Acta Est Fabula emanates again,with Marie inhabiting the blade and becoming a Buddha-like entity. This ending was implied by the fact that Mercurius didn't reset the world after the guillotine was shattered by Machina,when the God talked to Ren,he said that Ren could have been Zarathustra again,fighting thus for 20 years after his defeat at Gladsheim. Whe Sieglinde used her foresight to see the future,she saw Valeria Trifa,Reinhard Heydrich and Mercurius dying under the blade of Beatrice. This ending was confirmed by Masada himself on togetter when asked about said route and the "next episode" 20 years after the battle in Valhalla.[*citation needed*]
