Mackenyu (新田 真剣佑, born November 16, 1996) is a Japanese actor born in Los Angeles, California. He is the son of actor and martial artist Sonny Chiba. He attended Beverly Hills High School in their Advanced Placement Program and appeared in a few films and TV shows while growing up. As a young child, Mackenyu had many interests including horseback riding, Yabusame, Kyokushin Karate (he was placed third at the US Kyokushin Karate Nationals), gymnastics, water polo, and wrestling (for which he became the school representative). He was also into music, playing piano since he was 10 years old, and later participated in the brass band of his high school in Beverly Hills, playing saxophone, and flute. At the age of 15, Mackenyu watched a movie of Haruma Miura and got inspired to pursue acting professionally in Japan. He held on to the dream of co-starring with the actor once he established his career, which then came true in the movie adaptation of Gunjō Senki (2021). Mackenyu landed his first feature film lead role in Take a Chance (2015) and was featured in the acclaimed short movie Tadaima (2015) for which he won a best supporting actor award at the Asians of Films festival. He moved to Japan later in the same year. His fame grew in Japan after landing the role of Eiji Tomari in Kamen Rider Drive: Surprise Future (2015). In 2016, he made his stage debut in the Japanese musical Boys Over Flower (Hana Yori Dango: The Musical), which prepared him for his future major roles in the stage-musicals ZEROTOPIA (2018) and Hoshi no Daichi ni Furu Namida (2020). He had a prominent role in the two part feature film Chihayafuru Part I & II (2016) which made him a big name in Japan. Mackenyu started to expand his acting opportunities in Hollywood with a supporting role in the film Pacific Rim: Uprising (2018). In 2021, he starred as the final villain, Yukishiro Enishi, in the Rurouni Kenshin series. He portrayed Scar in the live-action sequel of Fullmetal Alchemist (2022). He gained global popularity when he landed the role of Roronoa Zoro in the live-action series adaptation of One Piece (2023). Drawing on his martial arts background, Mackenyu performs his own stunts and is highly skilled in sword fighting.

"One Punch Man" is an action-comedy that deconstructs the superhero genre with a dry, existential wit. In a world constantly besieged by "Kaiju-level" monsters and eccentric supervillains, society relies on the Hero Association, a corporate bureaucracy that ranks heroes based on popularity and power. Enter Saitama, an unemployed salaryman who trained so hard he went bald and broke his "limiter." He is now the strongest being in the universe, capable of defeating any enemy with a single punch. The conflict isn't about saving the world—Saitama does that easily, usually while worrying about supermarket sales. The conflict is his profound, crushing boredom and depression. He feels nothing: no thrill, no fear, no glory. The film follows his reluctance to take on a disciple, the intense cyborg Genos, and his navigation of the Hero Association politics that refuse to recognize his strength. The climax features the arrival of Boros, an alien warlord searching for a worthy opponent. It is a battle between a maniacal conqueror desperate for a fight and a depressed human desperate to feel something, anything, again.
