Synopsis:
In the futuristic world of Kivotos, where various academies hold sway over social life and defense, a threat emerges from another dimension: the Skibidi Toilet, a strange and brutal force that destroys everything without mercy. As Kivotos' future teeters on the brink of destruction, one hope rises: Sunaookami Satoru, Shiroko's older brother, who possesses the ability to manipulate time.
Satoru returns to the past after being revived by the sacrifices of his friends. Determined to change history, he establishes the Elite Kivotos Alliance Force, a secret elite force that recruits the best graduates from all academies to combat interuniverse threats.
However, the threat continues to grow. The Skibidi Toilet forces attack not only physically but also with mind-manipulating technology through dangerous audio. They even manage to take over the headquarters of the Kaiser PMC and begin spreading their influence throughout the academy.
Amidst the tension, several students from various academies, including Abydos, Trinity, Millennium, Gehenna, and the Other Academies, secretly learn this secret. An underground alliance forms, while Satoru and his generals plan a massive counterattack within a month. But the Skibidi Toilet isn't the real threat. Astro Toilet is. Can Satoru overcome this alone? Or will his friends, Sensei, and the entire Kivotos student to help him overcome this problem?
