Toaru Majutsu no Index II Episode 17

"Punishment Game" (罰ゲーム) is the seventeenth episode of the second season of the Toaru Majutsu no Index anime adaption, and the forty-first episode overall. It was first aired on February 4, 2011.

Synopsis
Accelerator soon wakes up, realizing that he has rested for two hours, and he focuses on the device that keeps his ability usable. According to him, he can only use his ability for 15 minutes at a time, and turning it off drastically cripples his ability to understand sounds.

He decides to take a shower, thinking that there is no one home. However, as he opens the door to the shower room, he finds Aiho and Last Order naked, with Kikyou only draped with a bath towel. Aiho tells them that she forgot that they have Accelerator at home, and Last Order is shocked to find out that Accelerator does not react to the sight of scantily clad females. She then asks why Aiho and Kikyou aren't causing an uproar. They cooly reply that they're adults and he's a kid, and there's no problem for a kid seeing an adult in the nude. She insinuates that they're old women for saying which results in her getting punished (by having her head crushed), this irritates Accelerator while watching and tells them to get better security.

Last Order later goes outside and talks to MISAKA 10032; meanwhile, Accelerator has just finished his shower and looks for Last Order, who is not around. It turns out that Last Order develops an urge to get 10032's goggles, which the clone refuses to. Last Order, however, manages to trick 10032 into following her and takes the goggles before running away.

With that, 10032 prepares her gun and declares that she will take her goggles back.
