Reze (レゼ), also known as Lady Reze or Bomb Girl, is a Bomb Devil (爆ボ弾ムの悪あく魔ま Bomu no Akuma) Hybrid from the Soviet Union, who was sent to Japan with the mission of stealing the Chainsaw Man's heart. While also displaying a rather sympathetic side to her, even her seemingly true reactions like blushing in his presence were the results of the harsh military training that Reze was subjected to from a young age.
