Ep 1. CHANGE THE WORLD

The second season of the anime Senran Kagura: Ninja Flash! begins with an episode titled "CHANGE THE WORLD". The episode is set in a world where ninjas coexist with modern society, but their existence is not widely known. The series centers around the lives of all-female ninja schools like Hanzo Academy and Homura's Crimson Squad, who train and fight each other.

The episode opens with the Homura's Crimson Squad – a group of rogue ninjas who have rejected the traditional ways of their school and run their dojo – returning from a mission. Yumi, the leader of the squad, shows concern over her friend Asuka, the leader of Hanzo Academy, who has been missing. Suddenly, they hear a loud explosion, and a giant shadow appears over the city.

As they get closer, they see that it is a massive robot rampaging through the city, causing destruction and chaos. The robot is controlled by a robotic shinobi named Fubuki who works for the "Yoma" organization, an evil group of technological ninjas who plan on taking over the world. The Homura's Crimson Squad encounters Fubuki, but they are unable to take down the robot. A new character named Renka appears, revealing that she is a part of Hanzo Academy's new third-year class and that she was sent by Asuka to assist them.

The episode sets up the dynamic between Homura's Crimson Squad and Hanzo Academy once again, with Renka's introduction. However, it is not until the end of the episode that the true strength of their bond is revealed. There is more to Renka's appearance than just helping the Homura's Crimson Squad defeat an enemy they can't handle alone.

"CHANGE THE WORLD" sets up the Yoma organization as the new antagonists, and it is clear that they have technological advantages as compared to the traditional ninjas seen so far in the series. The episode is packed with action scenes, showing off the various ninja techniques and abilities of the Homura's Crimson Squad while introducing new characters to the cast. The animation is crisp, and the choreography of the fight scenes is impressive.

Overall, "CHANGE THE WORLD" is a solid first episode that sets up the tone and direction of the second season of Senran Kagura: Ninja Flash! The episode sets up the new villains, introduces a new character, and establishes the Homura's Crimson Squad and Hanzo Academy dynamic once again. The anime stays true to its ecchi roots and will appeal to fans of the genre, but it also manages to balance it with action and drama. With the promise of more action, intrigue, and fan favorite characters, the second season of Senran Kagura: Ninja Flash! is shaping up to be an enjoyable ride for fans of the series.
