The ball is confused

When Yukito woke up, it was Amawa Shrine.But something is different from usual.The surroundings are steep rocky mountains, and in the sky there are invisible birds flying around, which should have been extinct.And in his hand he was holding a strangely shaped sword."The reason space-time has become distorted is because you made your energy experiments run wild!" Before you know it, Isao, the space rabbit next to you, said this.Isao explains to Yukito, who can't grasp the situation. This was in the health room of Maehane Academy, where Yukito and the others attend.There, school nurse Olga was conducting a new kind of energy experiment.Yukito sneaks into his room and takes advantage of the fact that he can't let go of his hands and plays a prank on Olga.Olga reluctantly feels it.And as the two were about to enter the game, Yukito accidentally touched the experimental device and made the experiment itself go out of control!Not only the two, but all of humanity, are lost consciousness due to unknown energy. According to Isao, time and space have been messed up in this world due to the outrage of the experiment.To restore this, we must reunit the seven sexual swords that were released into the world, and once again bundled together.And that can only be done by the person who caused the situation.
