The website also revealed that Ryota Ohsaka will voice the new character Cliff .
The episode title is “Eris no Goblin Toubatsu”. Episode 16 of the anime aired on October 31st, and showed the reunion of Rudeus and his father Paul. However, it did not show what Eris and Ruijerd did during that same period. The parallel episode will therefore show what happened that day.
The first part of the Mushoku Tensei anime premiered in January 2021, while the second part premiered on October 3rd.
