Spear Hero,” has delivered another dose of comedic chaos and unexpected character interactions. This episode, released on November 10, 2025, continues the unique school-life premise where popular characters from various Isekai franchises converge.

Episode 5: “Incoming! Spear Hero” — A New Face in Class 3
The fifth episode of Isekai Quartet 3 introduces a significant new element to the already crowded school environment: a transfer student in Class 3. The episode’s summary reveals that someone finally transfers into Class 3, bringing excitement, particularly for Yunyun, who is often portrayed as lonely. However, the new transfer student’s entrance is anything but ordinary, as their initial interaction with Yunyun involves an “unexpected” and rather peculiar response.
Without delving into excessive spoilers, the episode’s title hints at the arrival of a character associated with a “Spear Hero,” strongly suggesting the introduction of Motoyasu Kitamura from The Rising of the Shield Hero in a more prominent role within Class 3. Discussions around the episode indicate that this character’s unique perspective, where he perceives women as “pigs” (with notable exceptions), plays a central role in the humor and interactions. This quirk leads to humorous misunderstandings and reactions from the established cast, especially as he searches for Filo.
The Continuing Crossover Phenomenon of Isekai Quartet 3
Isekai Quartet is renowned for bringing together characters from popular Kadokawa-published light novel series, including Overlord, KonoSuba, Re:ZERO -Starting Life in Another World-, and The Saga of Tanya the Evil. The second season expanded this universe to include The Rising of the Shield Hero.
Season 3 further diversifies the cast by integrating characters from The Eminence in Shadow, adding another layer of comedic potential to the already chaotic school setting. Studio Puyukai continues to handle the animation, with Minoru Ashina returning as both director and scriptwriter, ensuring the series maintains its signature charm and humor. The opening theme song for Season 3 is “Isekai Concerto,” performed by the main characters, while the ending theme is “Kimi Iro, Boku Iro,” sung by Konomi Suzuki and Kashitarō Itō.
