Height 165 cm Occupation Nurse Hometown Chiba Shiki Murasaki is a former player from a previous round of the real-life Btooom! game. After having been betrayed by Masahito Date, she has been living on the island ever since. While seemingly simple-minded and even kind in the past, Shiki admits (a medical professional having sworn to do no harm) to committing cruel acts in the past. Her experiences with Masahito Date and the Btooom! game have jaded her, leaving her to assume a cynical approach to life, especially toward men, whom she regards with extreme distrust. She, however, after her experiences with Himiko and Ryōta Sakamoto, has opened up to others, revealing an emotional yet compassionate side to her.
