Occurring between episodes two and three during Golden Week, Yuri organizes a lethal picnic for the SSS where members attempt to eliminate one another using traps and gadgets. Most boys succumb to these dangers, leaving only Otonashi alive. Meanwhile, Girls Dead Monster members Miyuki and Shiori try to trap Iwasawa, but she survives every attempt without realizing the danger. When they deploy their final trap, a dangerous concoction, it accidentally lands on Hisako. This causes her to transform into a blood-thirsty monster that Angel is unable to stop.
