Sophia

Sophia Keren (ソフィア・ケレン), formerly known as Negishi Shouko (根岸彰子), was reincarnated as the vampire progenitor. She was born into the Keren family, a noble human family that governed Keren County, a town in Sariella.

Her parents are normal humans, so she attempts to hide the fact that she is a vampire before her appraisal ceremony when she comes of age; while she is a toddler, disaster strikes her new hometown and she is rescued by White and Ariel.

Appearance
As Negishi Shouko, she is often described as having a creepy appearance. She was extremely thin, with a pale and permanently dour face.

As Sophia, she is a peerless beauty, with extremely pale-white skin and blood-red eyes.

Personality
Sophia is pretty dense in certain situations but has no qualms about using her power to muscle through them if she can. Her nature as a Vampire causes her to lust for battle that can challenge her, but she is denied that by intense training that has made her overwhelmingly more powerful than almost everything within the System. This causes her to lapse into depravity or depression when she focuses too much on it.

Her previous identity of Negishi Shouko was a target of ridicule; due to this she has an intense dislike for anyone who insists on using her original name. This is also the root of her jealousy towards Shiraori, whom she believes is Wakaba Hiiro, the queen of the class in their previous life. This jealousy makes it easy for her to obtain the title Ruler of Envy and the skill Envy.

Sophia is extremely grateful for Ariel, without her intervention during the conflict, she might not have even survived.

Character File
The only daughter of the noble Keren family in Sariella. A reincarnation who retains her memories of being Shouko Negishi, a high school student in Japan. She is actually a vampire progenitor, a being who should no longer exist in this world. Displaying unbelievable power, she often stands in the way of Shun and the others. She serves a being she calls Master. Born to a human family, she initially lived without any contact with Demon and the like, but after encountering the Nightmare of the Labyrinth as a baby, her life quickly became very turbulent.

Status
In Volume 4, the skill Undying Body was translated as Immortality. Due to this skill being inherently different from the Immortality skill that Kumoko has, this skill's translation was changed to Undying Body in Volume 6. On the wiki, the Appraisal block for Volume 4 - Final Chapter has been updated to Undying Body for consistency in System translations. Please see Patch Notes for other translation changes.
