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. As Tsugumi states her belief that Anya won't leave the city, mentioning the feelings she sensed from her. Jacqueline, sensing what Tsugumi may be going through, has Kim heal her injuries and lets her go to help her friends. Hitching a ride with Liz and Patty, Tsugumi reunites with Anya, the two resolving to rescue Meme and managing to perform a Soul Resonance, which gives Tsugumi's halberd form wings. Sensing the two's bonds, Akane directs them towards Stein, who admires their resolve and gives them an antidote made from Meme's blood. Following a messenger bat, Tsugumi and Anya soon arrive at the top of a bell tower, where Shaula and Meme await.
