[Completed] [This novel features a gender swap and no romance. A blend of Blade and Sword Domain and No Game No Life.] Miss Okita Souji wakes to find herself caught up in a drawn-out war, in a place where beings other than humans exist. Humanity here is on the brink of extinction, forced to huddle underground and eke out a meager existence. She resolves to give these people hope.
"Riku, do you believe humanity can defeat the gods and win this war?"
"Whether you believe it or not, I came from a world just like that, one ruled by humans."
"All right, let's build a better tomorrow together."
Just as she decides to begin the fight, the scene suddenly shifts, and her consciousness returns to a psychiatric hospital.
"Sis, are you okay? Are you having another episode? What were you talking to yourself about this time?"
She has a younger sister named Asada Shino. Here, she seems to be nothing more than a mental patient.
"No... those people are real... I'm not sick... I'm not sick. The war has to end. The people over there need my help."
"Doctor, Sis is having another episode!!"
"I recommend increasing the dosage. Let's see if that keeps her stable!"
