Saison d'épisodes spéciaux, ils peuvent soit présenter une nouvelle aventure, soit en retracer une ancienne.

Class 3E and while some things have changed, the class assignment is still the same: kill their teacher before the end of the year. Easier said than done since Koro Sensei's made it clear he won't go down without a fight.

Filled with regret, Hikaru, Umi and Fun return to Tokyo. Dark forces still brew with the broken land of Cephiro and the foreign leaders of Autozam, Fahren and Chizeta, seek the crown of the pillar so they may seize its limitless power. Now the girls are summoned back by an unknown force and must find a new Pillar before Cephiro ceases to exist. But the land is plagued by a new type of monster, led by Debonair and Hikaru's alter ego, Nova!
