Death Game! The Missing Classmate

After leaving the museum, the group is confronted by the modified souls, who tell them that one of their core group has been replaced by an imposter, and they must find out who that is before noon, or everyone in their school will be killed. While out in the hall at Ichigo's school, he becomes suspicious of Renji thinking that he is the imposter. He tells him to "take it off". Ichigo means Renji's gigai but he doesn't specify it. The class goes out to see what the commotion is about and find Ichigo and Renji in a suggestive position. As the group attempts to find the imposter, Tatsuki Arisawa, one of Ichigo's classmates, disappears. At the last minute, it is decided that the imposter was posing as Chad, but the modified souls had already kidnapped the students.
