第 20 集: Karma 躲避瓦斯攻擊，Nagisa 女裝偽裝以開闢通往 VIP 層的通道

Evading Grip's hands that could kill him if they make contact, Karma is seemingly hit by some gas that Grip had borrowed from Smog. However, having learned not to underestimate his opponents, Karma avoids it and hits Grip with some gas of his own, allowing the students to bind him up and move onward to the sixth floor. Needing to unlock the back entrance of the stairs to help the others reach the next floor undetected, the girls make their way through the lounge while Nagisa, dressed up as a girl by the others, is hit on by a rich kid named Yuuji. While trying to impress who he thinks is a cute girl, Yuuji ends up angering a yakuza, but the girls manage to knock him out, opening a way onward in the process. After leaving Yuuji, who Nagisa encourages to play it straight from now on, the students move on to the VIP floor, where Terasaka knocks out some bodyguards using some stun-guns, obtaining some pistols that are given to Chiba and Hayami. Needing to get through a theater stage to get to the next set of stairs, the students face off against their next opponent, Gastro. (Source: Wikipedia)
