Olka Gretcher

Olka Gretcher is the only member of the Ostanian underworld organization 'Gretcher Family' to have survived its violent internal collapse. Determined to shield her young son from those hunting them down, she underwent plastic surgery and assumed the false identity of 'Sadie Grey'. Arranged by the assassination network known as 'Garden', she boarded a cruise ship as part of her escape plan, placing her at the center of Yor's protection mission during the cruise arc. Even while surrounded by constant danger, she demonstrates an unwavering will to survive alongside a deep and tender love for her child.
