The new cast additions include acclaimed voice actors Katsuyuki Konishi, Yoko Hikasa, and Mari Yokoo, all of whom will portray important figures connected to Eris’s swordsmanship journey.
What Is the “Eris Training Arc”?
The “Eris Training Arc” focuses on one of the franchise’s most beloved characters, Eris Boreas Greyrat, and explores the events that occurred after her emotional departure from Rudeus.
During Season 1, Eris and Rudeus were caught in the devastating Teleportation Incident, which scattered countless people across the world. Together with the Superd warrior Ruijerd, they formed the adventurer party Dead End and embarked on a dangerous journey across the Demon Continent to return home.
Throughout their travels, Eris matured significantly and developed deep feelings for Rudeus. However, after witnessing Rudeus being overwhelmingly defeated by the Dragon God Orsted, Eris realized the vast difference in strength between them and the powerful enemies they could face in the future.
Determined to become stronger and worthy of standing beside Rudeus, she left without fully explaining her intentions and embarked on a personal journey to master the sword. Season 3 finally reveals what happened during that period and showcases the intense training that helped shape Eris into a formidable warrior.
New Characters Introduced in Season 3
Aubert Corvette (Voiced by Katsuyuki Konishi)
Aubert Corvette is one of the key figures introduced during the Eris Training Arc.
He is a practitioner of the North God Style, one of the three major swordsmanship schools in the world of Mushoku Tensei. Aubert holds the prestigious title of North Emperor, signifying his extraordinary skill and influence within the martial arts community.
Known for his eccentric personality and unpredictable behavior, Aubert serves as both a mentor and a challenge to those seeking to master advanced sword techniques.
Isolde Cruel (Voiced by Yoko Hikasa)
Isolde Cruel is a highly skilled swordswoman who practices the Water God Style, another of the world’s legendary sword schools.
As the granddaughter and disciple of the Water God herself, Isolde possesses exceptional talent and discipline. Her strong sense of honor and dedication to the sword make her an important figure in Eris’s growth and understanding of different combat philosophies.
Fans are particularly excited to hear Yoko Hikasa bring Isolde to life, given her impressive history of voicing strong and charismatic female characters.
Reida Reia (Voiced by Mari Yokoo)
Reida Reia is a legendary master of the Water God Style and carries the title of Water God, one of the highest honors a swordsman can achieve.
As Isolde’s grandmother and mentor, Reida represents the pinnacle of Water God swordsmanship. Her appearance introduces viewers to one of the most respected martial traditions in the Mushoku Tensei universe and further expands the series’ rich world-building.
Why the Eris Training Arc Matters
For many fans, Eris’s sudden departure at the end of Season 1 was one of the most emotional moments in the series.
While Rudeus interpreted her departure as rejection, readers of the original light novel understood that Eris left because she felt inadequate and wanted to become stronger for the sake of their future.
The Eris Training Arc fills in these missing chapters of her story, offering:
- A deeper look at Eris’s personal growth
- New insights into the world’s swordsmanship systems
- Powerful character development
- Important connections to future story arcs
- Expanded lore surrounding the North God and Water God schools
This arc also highlights Eris’s transformation from a hot-headed noble girl into a disciplined and fearsome swordswoman.
