Nathan Mahler



Nathan Mahler is the last of Diva's chevaliers.

Nathan is the most colourful (literally and metaphorically) of all the chevaliers, presumably fitting into the stereotype of the flamboyant homosexual.

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

 * James Nathan repeatedly rubs himself against James and teases him about his "Mama" - seemingly to annoy him rather than out of any genuine affection.


 * Karl Although having very little direct contact with Karl, following his death he asks the others "Are you sad that our brother is dead?" showing a hint of sympathy to non-conforming chevalier.


 * Amshel The antagonism between Amshel 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. Nathan, while obedient for the majority of the series, shows to emotion following Amshel's fight. He claims he did not realise 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.

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, head of Diva's chevalier knows who he really is.

Among fans there are two theories as to whom Nathan really is:
 * Saya and Diva's Father
 * Saya and Diva's Uncle

The second theory (that he is their uncle, which would make him the chevalier of their mother) 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.
