Toaru Majutsu no Index II Episode 23

"Before the Outbreak of War" (開戦前) is the twenty-third episode of the second season of the Toaru Majutsu no Index anime adaptation, and the forty-seventh episode overall. It was first aired on March 25, 2011.

Synopsis
Minutes later, Accelerator is dropped off at District 10, where he is tasked with the primary objective to eliminate Komaba Ritoku. Upon first glance, he notices the different stealth tactics the Skill-Out have placed along the area: electric fences to short out security robots, lengths of cloth draped across rooftops to shroud possible escape routes, not to mention the destruction of cameras throughout the district.

Soon, Accelerator receives a call from Tsuchimikado, who warns him of various things. First, to not trust his fellow agents from GROUP. Second, to finish the job quickly, as Musujime Awaki has already started. Accelerator is surprised to find out that it would become a competition in the end, but Tsuchimikado tells him that Musujime only wanted the bounty.

Tsuchimikado soon closes the line, and with Accelerator entering esper mode, he estimates the time needed to finish off the job is ten minutes.

Meanwhile, Awaki is already fending off the members of Skill-Out, with nine objetives (money hideouts) already destroyed by her attacks. Soon, a towering figure of a man stands in her way... the primary target, Komaba Ritoku.

With a smile of surprise and relief, she prepares herself as she faces the Skill-Out leader.
