About Chainsaw Man and the Reze Arc
Chainsaw Man is the critically acclaimed dark fantasy action manga created by Fujimoto Tatsuki. Originating in Shuukan Shounen Jump, the series has continued its thrilling narrative with a second part currently running in Shounen Jump+. The story introduces us to Denji, a young man burdened by his parents’ immense debt, whose life takes a drastic turn after forming a contract with Pochita, the adorable Chainsaw Devil. As a Devil Hunter, Denji navigates a dangerous world, ultimately transforming into the formidable “Chainsaw Man” with a devil’s heart following a pivotal incident.
The series exploded in popularity following the TV anime’s broadcast in October 2022. Gekijouban Chainsaw Man Reze-hen brings the fan-favorite “Reze Arc” to life on the silver screen, serving as a direct continuation from the TV anime’s breathtaking finale. Since its nationwide release on Friday, September 19, the film has immersed viewers in Denji‘s journey as he is captivated and swayed by Reze, a mysterious girl he encounters by chance, propelling him into an unpredictable and thrilling fate.
The newly released promotional video beautifully captures the innocent and luminous figures of Denji and Reze. Their chance meeting amidst a sudden downpour, serene conversations at a cafe, and a stolen moment of youthful exuberance while sneaking into school to enjoy the pool at night—these impressionistic scenes weave together to portray their dream-like days together, leaving a lasting impression on viewers.
