Asuramaru

"*Why is it? Why is he so self-sacrificing? He and I are connected, both mind and soul... I should know the answer to that.*"

—Asuramaru's thoughts about Yu

**Asuramaru** (阿修羅丸 *Ashūramaru***?**, lit. "Perfect Asura"), birth name **Ashera Tepes** (アシェラ・ツェペシ *Ashera Tsepeshi***?**), is the older brother of Krul Tepes and a high-ranked possession-type demon of the Black Demon Series. He formed a contract with Yūichirō Hyakuya and became his Cursed Gear in *Seraph of the End: Vampire Reign*.

## Personality

Ashera, in his days as a human one thousand years ago prior to the series, enjoyed viewing the blue sky and gazing at the sun. He regrets leaving his sister behind and becoming a demon. He also cares for his family. Unlike his sister, Ashera was not thankful for everything they had since he was from a noble family.

Asuramaru is a blood-thirsty demon who was originally a vampire. He delights in drinking Yu's blood and goes into a giddy high after Yu feeds it to him for the first time. As a possession-type demon, he is described as particularly nasty and aggressive.

Like all demons, he is manipulative and uses nightmares to consume the one he possesses in order to take over his host's body. At the beginning of the series, he interrupts his host's dreams every night, making Yu tired during the day. After all, the only reason he allows Yu to borrow his power is for the future opportunity to take over his body.

After Yu loosens the curse on him and the two battle for dominance, Asuramaru eventually gives in to Yu's compassion and submits to him, which also includes him to stop giving Yu nightmares.

Even so, Asuramaru thinks of humans as vile, greedy creatures who are even worse than vampires and demons. He considers them to be taboo-breakers who will destroy the world, and also thinks no better of angels as he considers them to be disgusting. Although he is fully aware of Yu going insane on the battlefield and of the experimentation done on him, Asuramaru does not reveal any of these vital secrets to his host, thus he is more of a trusted enemy rather than a friend or ally.

Despite his hatred of angels, he helped Yu with his battle against the 6th trumpet after Yu convinced him. As time passes he becomes more considered, and curious, wanting to know about Yu's past, and in turn Yu later asks him about his past life. Much later Yu saves him from Shikama Doji.

Asuramaru becomes seriously annoyed when someone else disrupts his mind, much as Shikama Doji did. Asuramaru has also shown solicitude for his host Yu, as shown when he tried to get Yu out of Shikama Doji's grasp, hinting that he cares for Yu's status.

Asuramaru later regains all of his memories when he declared he will turn Yu into a demon, but the latter was nearly in sync of Yu as he was speaking through him to communicate.

Asuramaru personality changes after regaining his memories as a human, as he starts to become more merciful and even nicer in his demon-nature side. Even though he had the opportunity to possess Yu's body, he didn't possess him in the end, and told Yu about Mika's last words, Asuramaru remarks how hard life can be hard when Yu cried as well. He even did show Yu Mika's sacrifice to give him a reason to live, and not simply throwing his life away.

## Forms and Abilities

* Asura-Kannon

* **Basic Form**: Asuramaru appears as a black katana with the edge of the blade being a light green. Even without being called, his power is immense.

* **Asura-Kannon**: A special technique using Asuramaru that materializes dozens of floating swords roughly in the shape of a fan. This type of ability should be impossible for a possession-type demon.

		- **Asura-Kannon: Ten-Thousand Blades: Knot of Fate**: This technique creates a much wider range of the warped space that can cover an entire building and more, and millions of thousands of swords surfaces then materializes in the warped space. It has enough destructive force to shatter the surrounding area in the warped space with a homing effect at the target.

	+ **Asura-Kannon: Infinite Blades: Knot of Fate**: This technique is similar to Asura-Kannon but with numerous swords that materializes horizontally with a much wider range with a circular form, they then surround the target and impale them at high speed simultaneously.
