リザ, Lizard Kishresgalza
from Death March to the Parallel World Rhapsody
Originally a slave belonging to a man named Uusu, but became master-less after his death. She became Satou's slave after leaving the labyrinth. Her forename is derived from her real name rather than the word "lizard" (at least according to Satou), as her real name is too hard to pronounce for human tongues.

Death March to the Parallel World Rhapsody
29-year-old programmer Suzuki Ichirou finds himself transported into a fantasy RPG. Within the game, he's a 15-year-old named Satou. At first he thinks he's dreaming, but his experiences seem very real. Due to a powerful ability he possesses with limited use, he ends up wiping out an army of lizard men and becomes a high leveled adventurer. Satou decides to hide his level, and plans to live peacefully and meet new people. However, developments in the game's story, such as the return of a demon king, may cause a nuisance to Satou's plans. (Source: MangaHelpers, edited)
