"Tiger Mask W" is a wrestling-themed anime that serves as a modern revival of the classic "Tiger Mask" series, blending sports action with dramatic storytelling. The narrative centers on Naoto Azuma, a young wrestler who adopts the persona of Tiger Mask to honor his mentor, Takuma Fujii, a former wrestler known as the original Tiger Mask. Naoto's journey begins when he joins the New Japan Pro-Wrestling (NJPW) promotion, aiming to challenge the corrupt Global Wrestling Monopoly (GWM), an organization that exploits wrestlers and manipulates the sport for profit.

The GWM is led by the ruthless Mr. X, who employs a roster of elite wrestlers, including the menacing Tiger the Dark, a rival masked wrestler. Tiger the Dark is later revealed to be Naoto's childhood friend, Yūji Nagata, who was lured into the GWM's schemes. The rivalry between Tiger Mask and Tiger the Dark becomes a central conflict, symbolizing the struggle between integrity and corruption in the wrestling world.

As Naoto fights to dismantle the GWM's influence, he encounters a variety of allies and adversaries, including Haruna Takaoka, a journalist who supports his cause, and Ruriko Nishino, a former wrestler who provides guidance. The series incorporates real-life NJPW wrestlers and events, adding a layer of authenticity to its portrayal of professional wrestling. The plot explores themes of redemption, loyalty, and the ethical challenges faced by athletes in a competitive industry.

The anime balances intense wrestling matches with character-driven drama, showcasing Naoto's growth as a wrestler and his determination to uphold the legacy of Tiger Mask. The series pays homage to its predecessor while introducing new elements to appeal to contemporary audiences, making it a compelling entry in the sports anime genre.
