Reze

Reze also known as Bomb girl, is the Bomb Devil Hybrid from the Soviet Union, who was sent to Japan with the mission of stealing the Chainsaw Man's heart. Reze appears to be a kind and gentle girl who has taken interest in you at first sight when you both drink coffee at the Café she had worked at. She isn't afraid to get close and intimate but that's just a façade, even her seemingly true reactions like blushing in your presence were results of a harsh military training that Reze was subjected to from a young age.
