Aslan, Astharoshe

アスタローシェ・アスラン

Astharoshe "Asthe" Aslan, Duchess of Odessa and Kiev, serves as an undercover agent for the New Human Empire. She is a direct, no-nonsense individual who holds a very low opinion of Terrans, describing them as barbaric and stupid, among other things. Her view of humans, however, seems to have been shaped primarily by Empire propaganda combined with her limited exposure to or understanding of them. Asthe considers being called a "vampire" an insulting slur and refers to herself only as a Methuselah. Asthe fights with a weapon known as the Sword of Gae Bolg. As the most powerful close-combat weapon found among the Lost Technology relics, the sword uses ionized xenon gas to create a high-density, high-temperature plasma blade capable of cutting through anything.
Asthe's perspective on humans begins to shift after she is sent to Venice to arrest Endre Kourza, a vampire mass murderer whose latest round of killings in Vatican territory could spark a war. As part of her mission, she is partnered with Father Abel Nightroad from the AX Agency. When the two locate Endre, Asthe becomes solely focused on killing him because he murdered her partner. She is so blinded by rage that she destroys the Rialto Bridge, killing and wounding many humans who had gathered for a festival. Abel also sustains injuries while protecting her from her own sword, which flew back at her during the explosion. She greatly regrets her actions and keeps a better handle on her emotions when they pursue Endre again and arrest him. Although she initially berated Abel for calling himself her partner—a word of special meaning to Asthe—he earns enough of her respect by the end of the mission for her to call him her partner. She also becomes more accepting and tolerant of humans in general.
Her partnership with Abel becomes an important step in the secret peace negotiations between the Vatican and the Empire. She is later assigned to shelter the Vatican diplomats and the Earl of Memphis following the Rosenkreuz Orden's attempt to assassinate Cardinal Caterina. Through these events, Asthe also becomes a core Empire representative in the effort to stop the Rosenkreuz Orden's continued attempts to start another war between the Methuselah and Terrans.
In the novels, the partner that Endre killed was the Countess Len Yearnoshe; however, in the anime series, her partner is changed to a male, and it is implied that they were lovers.
In the anime, she is first sent to investigate an incident suspected to be connected to a vampire mass murderer and is reluctantly partnered with Abel. Astharoshe is a direct, no-nonsense individual who harbors a low opinion of humans. Despite the fact that she can be harsh, Astharoshe has also been shown to be very caring and understanding on some occasions. She has proved to be a skilled fighter and wields a large spear that can extend on her command and fires massive blasts of energy from its tip.
