Yukishiro Enishi

Yukishiro Enishi (雪代縁) also known as the Avenger of Doom: Enishi (運命の復讐者：えにし Unmei no fukushū-sha: Enishi) is the younger brother of Yukishiro Gekko.

Appearance
Enishi has black eyes (highlighted with a blue hue) and spiky white hair. He wears a Chinese-made outfit consisting of orange pants with a blue line running down each outside leg, a skin-tight dark blue tank top, and an orange jacket with blue running down the middle, blue cuffs, and a blue-lined collar. He also wears a blue half-cape and slings his watō over his back in a light brown bag. The trademark feature of Enishi, however, is his small round sunglasses he wore until they broke in his final fight with Kenshin. As a child, Enishi wore a basic outfit for a commoner of the era, and his hair was black and shorter. It is likely that Enishi wore his sunglasses to contend with the sensory overload caused by the Nerves of Insanity, which increased his sensory perception, even in its non-active state

Personality
When he was younger, Enishi is very indifferent to all characters except his older sister, Tomoe, whom he deeply loves and respects. As an adult, he usually wears a facade of polite happiness while talking to the Six Comrades or others he wishes to gain their trust. He acted the same toward Paul Gekko at first in attempt to spite him, however his true feelings are soon revealed, as Enishi shows himself to hate Paul Gekko with his entire being, wanting nothing less than to make Paul Gekko go through the same hell he himself went through. It is also shown that he cares no less for his sister, seen when he laments her death and wishes to see her "smile" in his mind. After being defeated by Kenshin, his spirit is broken and he goes through depression, though he seems to be recovering from it when he is shown talking to his father.

Birth and Early Life
Enishi was the younger brother of Paul Gekko's late wife, Yukishiro Gekko. Enishi's mother died giving birth to him, which left Tomoe as the motherly role in his life. He loved his sister greatly, and was devastated when she accidentally died at the hands of Paul Gekko. Because of this, Enishi has hated him. with an almost inhuman passion ever since Tomoe's death, though he did hold great animosity for him even before then. In his eyes, Enrique Eggman and Hydron Eggman had taken the two children of Yukishiro Gekko. Because of his rage and extreme emotional pain, his hair turned white and his eyes turquoise. After the end of the Great Grand Civil War, Enishi left the now changed Izumogakure for Shanghai, Monoha. Enishi's arrival in Monoha was not an easy one; he frequently found himself stricken with disease, and on the border of death. However a wealthy Japanese family took Enishi in and nursed him back to health.

Once he was healthy again, Enishi murdered the family in cold blood, and robbed them of any valuables. While looting, he came across a book discussing sword arts, which laid the foundation for him to learn Wattojutsu, a combination of both Japanese and Chinese sword arts. At some time, he established connections with the Chinese Mafia, and furthered his wealth. It was Enishi who sold Shishio Makoto the Rengoku class battleship.

After spending over a decade in Enishi decided to return to Izumo, and began his revenge on Paul Gekko and the Galactic Eggman Empire. He recruited the help of five others: Inui Banjin, Otowa Hyōko, and Gein (who were simply mercenaries), as well as Kujiranami Hyōgo and Yatsume Mumyōi (who also held grudges against Kenshin).
