Nathan Mahler



Nathan Mahler is the 7th and last of Diva's chevaliers who first appears in episode 20.

Personality
Unlike the more dour vampires of the series, Nathan is the friendliest and most colourful (literally and metaphorically) of all the chevaliers, presumably fitting into the stereotype of the flamboyant homosexual. Like Lewis from Red Shield, Nathan plays the comic relief for Cinq Fleshe. Because of his grandoise nature and the fact that he is openly gay, the fans have playfully dubbed him the "third queen."

Despite his bright and cheerful personality, Nathan can be deeply threatening when needs be, even challenging Amshel's authority. He himself never gives orders but none of the other chevaliers question him.

Relationships
Nathan does not appear to play any major role in the battle between Saya and Diva, neither attacking Red Shield or defending the other Chevaliers from attack.

James

Nathan interacts with James more than any other chevalier, repeatedly rubbing himself against James and teases him about his "Mama" - seemingly to annoy him rather than out of any genuine affection. Using his great speed (which is faster than any of the other already swift chevaliers) he also steals his pocketwatch containing a photo of Diva. Despite this he does show some civility towards James when asking him about his devotion to Diva.

Karl

Karl and Nathan are never seen directly speaking to one another. Although having very little direct contact with him, following Karl's death he asks the others "Are you sad that our brother is dead?" showing a hint of sympathy to non-conforming chevalier.

Amshel

Although Nathan shows slight compassion towards his fellow chevaliers (including Hagi), he shows none towards Amshel. The antagonism between he and Nathan is not seen until the very end of the series. Amshel tries subtly to provoke Nathan while at the same time seeming wary of him. In the penultimate episode where Amshel fights Hagi to the death, Nathan shows no emotion following his demise. He claims that all Diva wanted was a family.

Diva

Although he is the last to meet Diva, he is the only chevalier she does not lose interest in following her pregnancy. Nathan has a paternal attitude towards her and likes to affectionatly fuss over her looks and clothing.

Interestingly while watching her singing (in her Riku form) Nathan firmly tells Amshel that once the project was over he could have her children, but that he was taking Diva, emphasising his order by cracking the glass Amshel is holding merely by looking at it. Amshel himself does not react. This is the second time Nathan threatened one of his fellow chevaliers.

Chiropterid Form


In his vampire form, Nathan is significantly larger than other chiropterans, including the chevaliers. Excluing a scene in the 4th OP, Nathan is also the only chiropterid who never fights Saya or Red Shield. One one occassion he actively defends Saya from attack by James. Nathan's powers are also unclear - he is thought to be a trickster or illusionist. He can either move so fast that he cannot be seen with the naked eye, or he can change his form to trick others into not being able to see him. He also appears to have a form of telephathy stronger than the other chevaliers, seemingly able to break glass with his mind.

Nathan's death puzzled the audience. As soon as Diva died, he asked Saya to kill him as he had no more reason to live. He says "Good girl" while Saya slices him in half, and thanks her before collapsing into the orchestra pit. His seemingly mundane dead scene however changed when in the final episode several reporters try to talk to Van Argeno. Nathan clearly appears in reporters clothing before disappearing when another man walks in front of him.

Origins
Although the audience is only shown how a few of the chevaliers became vampires, who Nathan really is becomes much more of a mystery towards the end of the series. Not even Amshel knew who he really was. It's not clear how or when Nathan became Diva's chevalier because of the (intentional) gaps in the plot. He says in his first apperance in episode 20 that he is the only one who has yet to meet her, meaning she had not yet woken from her 30-year hibernation cycle when he became her chevalier.

Among fans there are two theories as to his real identity:
 * Saya and Diva's Father
 * Saya and Diva's Uncle - which would make him the chevalier of their mother

The second theory is more popular, firstly because he is clearly homosexual so is unlikely to father children, and secondly because he is far more interested in Diva than Saya and speaks of "History repeating itself", leading fans to presume that Saya and Diva's mother was blue-eyed. This also begs the question as to whether or not chevaliers can be "inherited" (as he guarded Diva more than he guarded Saya). In Episode 48, a conversation between Amshel and Nathan further suggests that Nathan is in fact the chevalier of Saya and Diva's mother:

"Nathan: The world exists as a shining stage for Diva so she can be adored. It was proclaimed even before Diva was born.

Amshel: You talk like you've witnessed it.

Nathan: Actualy, I did.

Amshel: Hmm?

Nathan: Years ago there was Saya and Diva and the mummy that was their mother. What she had then was a faithful chevalier just like her daughter today."
