While monitoring Chidori's apartment, Sousuke and his teammates spot a panty thief climbing onto her balcony. Sousuke subdues the culprit, but it turns out to be one of his classmates, Kazama Shinji, the military otaku. The two hit it off talking about Arm Slave specs while still sitting on the balcony. When Chidori discovers them after her shower, she (and her bat) isn't too happy.
