If you’re a fan of Super Sentai, Power Rangers, or the ever-popular isekai genre, the 2025 anime The Red Ranger Becomes an Adventurer in Another World (Japanese: Sentai Reddo Isekai de Bōkensha ni Naru) is a must-watch. This delightful series, which aired from January to March 2025, blends the colorful, action-packed world of sentai heroes with the fantastical adventures of isekai, delivering a heartfelt parody that’s both nostalgic and fresh. Here’s everything you need to know about this anime, why it stands out, and why it’s perfect for fans of both genres.
What Is The Red Ranger Becomes an Adventurer in Another World?
Based on a manga by Koyoshi Nakayoshi, serialized in Square Enix’s Monthly Shōnen Gangan since October 2020, this anime follows Tōgo Asagaki, the Red Ranger of the Bansou Sentai Kizuna Five. After a climactic battle against the villainous Breakup King, Tōgo is unexpectedly transported to a fantasy world filled with magic, monsters, and demons. Unable to return home, he becomes an adventurer, transforming into his superhero alter ego, Kizuna Red, to protect the people of this new world.
Tōgo teams up with a colorful cast, including:
- Yihdra Arvoln, a young mage striving to restore her family’s honor and make magic accessible to all.
- Princess Teltina Liz Wagrel Alvarost, who fights to stop demon seeds from possessing people.
- Lowji Mist, Teltina’s bodyguard, who’s both smitten with her and envious of Tōgo’s heroics.
Produced by Studio Satelight (Fairy Tail, Log Horizon), the 12-episode series is directed by Keiichiro Kawaguchi, with series composition by Atsuhiro Tomioka, a veteran of Super Sentai shows like Bakuage Sentai Boonboomger. The anime premiered on January 12, 2025, on AT-X and other networks, with Crunchyroll streaming it globally, including an English dub that debuted on February 2, 2025.
A Loving Parody of Sentai Tropes
What makes The Red Ranger Becomes an Adventurer in Another World shine is its affectionate parody of Super Sentai and Power Rangers. Tōgo is the quintessential Red Ranger: hot-blooded, bond-obsessed, and slightly over-the-top. His signature catchphrases about “bonds” and dramatic transformation sequences—complete with explosions and a talking bracelet—feel straight out of a tokusatsu show. The anime leans into classic sentai tropes, like:
- Color-coded teams: Tōgo’s Kizuna Five squad includes Blue, Yellow, Green, and Pink Rangers, voiced by Super Sentai veterans like Masaya Matsukaze (Denji Sentai Megaranger) and Mika Kikuchi (Tokusou Sentai Dekaranger).
- Mecha battles: Tōgo summons the Maximum Kizuna Kaiser, a giant robot rendered with CGI to mimic the toy-like aesthetic of sentai mecha.
- Villainous organizations: The fantasy world’s enemies, powered by demon seeds, echo the “Monster of the Week” format of sentai shows.
The humor comes from placing Tōgo’s sentai logic in a fantasy setting. Locals are baffled by his transformation poses, random explosions, and refusal to use his strongest attacks early. Yihdra’s deadpan reactions to his antics add a layer of comedy, poking fun at how absurd sentai conventions look in an isekai context. Yet, the show never mocks its source material—it celebrates what makes sentai special: teamwork, justice, and heart.
A Fresh Take on Isekai
While The Red Ranger Becomes an Adventurer in Another World embraces isekai staples like adventurer guilds and fantasy worlds, it avoids the genre’s pitfalls. Unlike generic isekai protagonists, Tōgo isn’t a blank slate. His larger-than-life personality, rooted in sentai heroism, makes him a refreshing lead. The anime also balances its parody with sincere character development:
- Tōgo’s quest to help others while searching for a way home reveals his deeper loneliness, hinted at by his obsession with “bonds.”
- Yihdra’s journey to redeem her family’s legacy adds emotional weight to the comedic setup.
- The party dynamics, especially Lowji’s rivalry with Tōgo, keep the story engaging.
The series doesn’t overstay its welcome, wrapping up in 12 episodes with a satisfying, anime-original final battle. It avoids excessive fanservice and generic fantasy politics, focusing instead on adventure, humor, and heart.
Why You Should Watch It
- For Sentai and Power Rangers Fans: The anime is a love letter to tokusatsu, packed with references like the Kizuna Brace (inspired by Battle Fever J’s Battleceiver) and cameos from Super Sentai actors like Tetsu Inada (Tokusou Sentai Dekaranger). The in-universe Kizuna Five show even has its own theme songs by Ryusei and Akira Kushida.
- For Isekai Fans: The unique premise of a sentai hero in a fantasy world sets it apart from typical isekai. The blend of action, comedy, and light RPG elements makes it accessible and fun.
- Top-Notch Production: Satelight’s animation brings Tōgo’s battles to life, with vibrant transformations and fluid mecha scenes. The soundtrack, composed by Koichiro Kameyama, captures the energy of both sentai and fantasy.
- Heartfelt Moments: Beneath the parody lies a story about friendship and perseverance, making it resonate with viewers of all ages.
