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.
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.
Tsugumi becomes upset when she receives a letter from her mother informing her that her dog, Pochi, had gotten involved in an accident, and ends up lashing out at Meme for forgetting things so easily. That night, Tsugumi and Anya follow Meme during one of her sleepwalks, winding up at the hidden research room where they are discovered by Akane and Clay.
A series of tales that take place whilst the girls are growing pumpkins for Halloween. During the night, Tsugumi and Anya have to deal with Meme's unique sleepwalking, which proves to be a fearsome fighting style similar to drunken boxing, which Meme can only perform whilst asleep or unconscious. On another day, Meme wakes up with a bag full of cash, a sloth, and a missing eyebrow, with no recollection of what led her to this bizarre situation. As Meme's investigation continues to leave her with more questions.
Whilst Akane and Clay interview Maka and Soul about the incident, Tsugumi and the others are relieved to find Eternal Feather has survived thanks to the efforts of Dr. Franken Stein, though are none too pleased with his pranks. As Eternal Feather steadily recovers from her injuries, Stein reports his findings to Sid.
Tsugumi and the others get a bad impression from the Thompson sisters, Liz and Patty, who are working at Deathbucks whilst on probation, having spent most of their childhood living on the streets of Brooklyn. When they run into the sisters later that day, Anya prepares to stand against them with Tsugumi, but is outmatched by their ability to both transform into pistols.
