The main visual for Season 4 has also been revealed. It highlights Iruma Suzuki taking on a new challenge: the Music Festival, an event that tests the unity of the entire class. The Abnormal Class of thirteen students appear in dazzling costumes under the stage lights, capturing the spirit of their upcoming performance.

A teaser PV featuring a memorable trumpet motif has been released as well. As the class must come together to win the Music Festival, Iruma and his classmates suddenly remember their long-forgotten thirteenth member, Soi Purson.
Having lived by the creed of “never stand out,” Purson has long avoided interacting with others. The teaser hints at how he will respond to Iruma’s earnest invitation, and whether the class can unite all thirteen members on stage to claim victory. The curtain rises on a music-filled challenge fraught with obstacles.
