Whilst the rest of Death City celebrate Halloween with a Battle Festival amongst the EAT students, Kim and Jacqueline are tasked with watching over Tsugumi, who had been grounded for her actions. Meanwhile, as Akane and Clay escort Anya towards the airport, the city is suddenly overrun by NOT students turned into Traitors, which the EAT students have to fend off.

Having spread out Traitors across Death City, Shaula unleashes her magic, making the Traitors more powerful whilst also ordering some of them to kill themselves as she sees fit. Shaula then sends Meme to kill Tsugumi and Anya, with Anya attempting to subdue her to give Tsugumi the chance to administer the antidote.
