- "If you despise something you'll become a goblin."
- -Goblin Slayer's Older Sister
Goblin Slayer's Older Sister (ゴブリンスレイヤーの姉, Goburin Sureiyā no ane) was the sole loved one of Goblin Slayer during his childhood. Her death is the primary circumstance that triggered Goblin Slayer's obsessive trait to kill all the Goblins.
In the few times she is seen in flashbacks, she is seen wearing a long white and green dress with an occasional apron and styles her hair in a side ponytail draped over her shoulder.
Goblin Slayer's Older Sister was a caring and kind individual, notably for taking responsibility as Goblin Slayer's guardian after their parents died and for hiding her brother under the floor just before a horde of goblins broke into their home. She was also quite wise, evident when she advised her brother not to resent someone after seeing that he was envious of Cow Girl's departure to the city.
After her parents died from a plague outbreak she took it upon herself to raise her younger brother all alone. As he was too young to remember his parents, his older sister was the only family he'd ever known. Nonetheless, she was very intelligent and taught Goblin Slayer, and many of the children of the village, how to read, write, and do arithmetic. She also taught Goblin Slayer many stories and life lessons that he took to heart after her death; notably of how goblins came from the green moon, and how if one became envious of another, they would become a goblin themselves.
Goblin Slayer Side Story: Year One
When her village is surrounded and attacked by a goblin horde, she had just enough time to hide her younger brother under their house's floorboards and tell him to not come out no matter what happens to her. Immediately after, many goblins break into their house and quickly swarm, strip, and gang-rape her. After they are finished they kill her in cold blood; all the while her younger brother watches through a crack in the floorboards. Her efforts to hide her younger brother were not in vain however, as he survived the attack to become Goblin Slayer as an adult, albeit with some help from Burglar.
