Synopsis
Set between episodes two and three, during Golden Week, Yuri arranges for the SSS to go on a deadly picnic, which involves most of the members trying to kill each other with various traps and gadgets. As the boys largely fall victim to various traps, leaving just Otonashi alive, Girls Dead Monster members Miyuki and Shiori attempt to lead Iwasawa into various pitfalls, only for her to survive each one while remaining completely oblivious. They attempt to use their last trap, a dreadful concoction, but it instead lands on Hisako, who transforms into a blood-thirsty monster that not even Angel can stop.
