Oba, an alien who has fallen in love with Ouran, decides to sacrifice himself to save humanity by fixing the reactor.

The episode opens with the city of Tokyo in a state of panic. The alien mothership, which has loomed over the city for years, is now showing signs of catastrophic failure. The reactor inside the mothership is melting down, and the countdown to disaster is underway. People scramble to evacuate, the streets are chaotic, and the sense of urgency is palpable. The camera pans across the city, showing the fear and confusion of the citizens, but also the strange normalcy that persists in some corners.

Cut to Kadode and Ouran, the two main characters. They are in their usual setting, going about their daily routines. They notice that their phones have lost internet connection, but they don't seem particularly concerned. They talk about mundane things, laugh, and continue with their lives as if nothing is happening. The contrast between their calm and the chaos around them is stark.

Meanwhile, Oba, an alien who has developed deep feelings for Ouran, is watching the events unfold. He has access to the memories of the aliens and humans, and he knows that the meltdown of the reactor will lead to the end of humanity. He also knows that he is the only one who can stop it. He has the password to fix the reactor, but doing so will require him to enter the heart of the mothership, a place from which there is no return.

Oba makes the decision to sacrifice himself. He knows that if he goes, Ouran will be devastated. She has abandonment issues and has already lost many people she loved. Oba doesn't want her to blame herself for another loved one dying. He also knows that if she blames herself, she might do something drastic, something that could end the world.

Oba goes to Ouran to say goodbye. He explains what he is about to do, but she doesn't want to let him go. She threatens to shoot him to stop him from leaving her. Oba, in a moment of desperation, shoots her first. He doesn't want her to suffer, and he doesn't want her to blame herself. He leaves, knowing that this is the only way to save humanity.

The episode ends with Oba entering the mothership, the reactor meltdown continuing, and the fate of Tokyo hanging in the balance. Kadode and Ouran, still unaware of the larger crisis, continue their lives, seemingly unaffected by the chaos around them. The final scenes show the city in ruins, the mothership looming overhead, and the two girls walking away, their friendship unbroken.

The fate of each main character is as follows: Oba sacrifices himself to save humanity, entering the mothership and presumably dying in the process. Kadode and Ouran survive, continuing their lives in the aftermath of the disaster. The episode leaves their ultimate fate ambiguous, but it is clear that they are still together, their bond stronger than ever.
