Griselda

Griselda (グリセルダ) was one of the 10,000 players who were trapped in «Sword Art Online» and the former leader of the guild Golden Apple before it's dissolution.

Background
After the start of the death game, her personality developed in charismatic terms, capable enough of leading a guild. Before she was described as an obedient and timid wife, by her husband.

Sword Art Online
Described as the perfect wife (cute and obedient) by her real life and in-game husband Grimlock, real-name Yuuko took to SAO much better than her partner. At the birth of the game, she began to develop an active and lively personality distinct from her moderate real counterpart. This change worried the emotionally unstable Grimlock, provoking him to plan and carry out her murder at the hands of the killing guild Laughing Coffin.

She was killed when she was appraising a +20 agility rare ring drop on the frontlines. She then later appeared in soul, smiling while thanking Kirito and Asuna for their assistance in revealing the mystery behind her death.
