Reze

A Soviet hybrid sent to steal a heart who found one of her own.

Reze is a central antagonist and tragic figure from Tatsuki Fujimoto's Chainsaw Man manga, specifically leading the "Reze Arc." On the surface, she appears as an ordinary café employee, but her true identity is the Bomb Devil. Originating from the Soviet Union, she was sent to Japan with the specific mission to seize Denji's heart. As of now, no official voice actor has been announced for the anime adaptation of the Reze Arc; any claims regarding a Japanese or English voice cast are currently fan speculation. Reze was inspired by the heroine of the animated film Jin-Roh: The Wolf Brigade. Creator Tatsuki Fujimoto revealed that his favorite character is Reze, intentionally crafting a story where she does not become an ally or end up with Denji so they could "carry that weight forever."

Lore & Background

Reze's backstory is defined by trauma and state manipulation. She was one of many children taken by the Soviet Union for human experimentation, a program designed to cultivate super-soldiers loyal to the state. Through harsh military training, she enhanced her innate abilities to become a Weapon Human fused with the Bomb Devil. Her mission brought her to Japan where she first encountered Denji at the café where she worked. Her warm demeanor caused Denji to mistakenly believe she had feelings for him, creating turmoil as he already admired Makima. Reze invited him on a date to a school where she taught him to swim, and later they watched fireworks together. During the festival, she confessed her feelings and proposed running away; Denji agreed ('Okay') before she revealed her true identity. She then kissed him and revealed that she was the Bomb Devil sent to seize his heart.

Reader's Guide

Reze is widely regarded as the best antagonist and greatest female character in Chainsaw Man by Comic Book Resources, described as a deadly, beautiful, and mysterious "bad girl." IGN noted she perfectly embodies Denji's first love, while Polygon praised her as a captivating femme fatale. The Fandom Post highlighted that she demonstrated more sophisticated manipulation skills than Makima, despite appearing as a "manic pixie dream girl" who seemed too perfect to be real. Vamsi Krishna of FandomWire emphasized her complexity, noting her mission, training, and feelings contradicted each other until her death. In popularity polls, she ranked fourth with 19,079 votes in the first poll, fifth with 45,741 votes in the second, and took first place with 205,775 votes in the third. Her legacy includes ranking 16th in the "Top 20 Single Words" category of the 2025 Internet Buzzword Awards.
