by New Main Promotional Video Reveals Action, Adventure, and Daily Life in the Labyrinth Kingdom
The upcoming TV anime The World’s Strongest Rearguard: A New Explorer in the Labyrinth Kingdom has unveiled its highly anticipated main promotional video (PV), giving fans a deeper look at the series ahead of its July 2026 premiere.
The newly released trailer showcases the anime’s exciting blend of fantasy adventure, strategic battles, and character-driven storytelling. Alongside action-packed combat sequences, viewers are also treated to glimpses of the everyday interactions and growing bonds between the main characters.
The PV additionally features previews of both the opening and ending theme songs, offering fans their first opportunity to experience the musical atmosphere that will accompany the series.
With its unique take on the isekai genre and focus on a support-class protagonist, The World’s Strongest Rearguard is shaping up to be one of the notable fantasy anime releases of Summer 2026.
What Is The World’s Strongest Rearguard About?
Based on the popular light novel series by Towa, The World’s Strongest Rearguard tells the story of Arihito, an ordinary man who is suddenly reincarnated into a fantasy world known as the Labyrinth Kingdom.
Unlike many isekai heroes who become powerful warriors or mages, Arihito receives the rare and often underestimated role of a Rear Guard—a support-class adventurer responsible for protecting allies from the back lines.
However, Arihito quickly discovers that his abilities are far more powerful than they initially appear.
By mastering support skills that combine:
- Offensive capabilities
- Defensive techniques
- Healing magic
- Party enhancement abilities
- Tactical battlefield control
He gradually becomes one of the strongest adventurers in the kingdom.
Together with a diverse group of companions, Arihito explores dangerous labyrinths, battles powerful monsters, and uncovers the secrets of his new world.
New PV Highlights Dynamic Battles and Teamwork
The newly released promotional video places a strong emphasis on the anime’s combat system and party-based adventure elements.
Several scenes showcase the main characters working together against dangerous monsters while utilizing their unique skills and abilities.
The footage demonstrates how Arihito’s role differs from traditional fantasy protagonists. Rather than relying solely on brute force, he supports his teammates through strategy, buffs, healing, and defensive abilities.
This team-focused approach gives the series a fresh perspective within the increasingly popular isekai genre.
The trailer also highlights:
- Fast-paced action sequences
- Magic-based combat
- Dungeon exploration
- Character interactions
- Humorous slice-of-life moments
- Emotional scenes between party members
These elements suggest that the anime will balance action and character development throughout its story.
Opening Theme: “License” by Redhair Rosy
One of the major highlights of the PV is the first preview of the anime’s opening theme song.
The opening track, titled “License,” is performed by Redhair Rosy and accompanies many of the action scenes shown throughout the trailer.
The energetic song complements the adventurous tone of the series while emphasizing themes of growth, determination, and teamwork.
Fans have already praised the song’s powerful sound and its compatibility with the anime’s fantasy setting.
Ending Theme: “How to Protect the Never-Ending Night”
The trailer also offers a preview of the ending theme song.
Titled “How to Protect the Never-Ending Night,” the song is performed by Inner Journey and presents a softer, more emotional atmosphere compared to the opening theme.
The ending theme appears to focus on the emotional bonds between the characters and the quieter moments of their journey.
Its reflective tone provides a fitting contrast to the high-energy battles featured throughout the series.
