Shirogane Takeru found himself inexplicably transported to a world that resembled his own in many ways, with one major difference: For nearly 30 years, mankind has been at war with the alien BETA, who have succeeded at wiping out over half of humanity and had nearly captured the entire Eurasian continent. As Takeru tried to come to grips with this bizarre new reality, he realized too late that the majority of humanity will be abandoned with the Earth, as the chosen few escape to the stars, hoping to find sanctuary.

Now, equally inexplicable reasons, he finds himself returned to the first day of his time in this alternate world. Will the experiences and knowledge he has gained allow him to make a difference?
But I never really thought about 
what the word actually meant.
.لكني لم أفكر أبدًا فيما تعنيه الكلمة بالضبط
Nie dachte ich über die Bedeutung
des Wortes „Land“ nach.
Nunca me había detenido a pensar
en su verdadero significado.
Nunca me había detenido a pensar
en su verdadero significado.
Je n’avais jamais vraiment réfléchi
à son sens.
Ma non avevo mai riflettuto 
sul reale significato del termine.
A verdade é que eu nunca pensei
de fato no que significa um país.
Я не особо задумывался 
о том, что такое родина.
