Castorice

Castorice (, CAST-er-iss, Chinese: 遐蝶; pinyin: Xiádié; lit. 'distant butterfly') is a character in the video game Honkai: Star Rail, developed by miHoYo. In the game, she is the demigod of death and one of the key figures in the story arc that takes place on the fictional planet called Amphoreus. She is afflicted with a curse that kills any living thing that comes into contact with her, and serves as an executioner because of this. She was released in version 3.2 of the game in April 2025. The character has received generally positive reviews from players and critics; commentators praised her character development centered around death and the tragic tone of her promotional videos, and also discussed her storyline involving the "dead dragon" Pollux. Her gameplay design, which sacrifices the entire team's health to maximize damage output and prevent teammates from falling, has also been well-received.
