What Has Happened So Far in Season 4
The fourth season focuses on the Music Festival, a major exam where students compete to raise their ranks. The Abnormal Class needs all 13 members to reach Rank 4, and winning the Music Festival is their only shot.
Episode 6 showed the festival officially starting, with Amduscias Poro appearing as a judge. Poro challenged the class using the “King’s Classroom” as a bet, which only made the students more determined to win.
The cast has grown this season. New voices include Setsuo Ito as Purson Soi and Takehito Koyasu as Amduscias Poro. Soi, who stays hidden using his magic, finally joined the class openly to help with the Music Festival.
What Episode 10 Will Bring
Episode 10 continues the Music Festival performances. The tension is building because Kiriwo has returned with a dangerous collar based on Iruma’s ring. Ali-sensei is already awake, which changes things for Iruma.
Poro-chan has an agreement with the Devil — literally, which means that it’s possible that he will not survive to become a full-fledged Demon.
The English dub for Season 4 releases on the same day as the subbed version. Laura Stahl voices Iruma Suzuki in English, with Stephen Fu as Asmodeus Alice and Kayli Mills as Valac Clara.
