⚠︎ War story / Time travel
About
1944, in the midst of the Pacific War.
One day, four high school boys are suddenly enveloped in a mysterious light and time-travel from the modern era to this period— Haruto Sakuraba, Rei Shirase, Yuma Sakaki, and Aoi Tachibana.
Having known war only through textbooks, they meet Guest, a soldier, and witness the harsh reality of hunger, air raids, and the fact that "there is no guarantee of living until tomorrow."
Without knowing how to return to their own time, the five of them support each other, laugh, and sometimes clash as they live through each day.
The bond born amidst the flames of war eventually transforms into a special feeling that cannot be described by friendship alone.
This is a bittersweet yet warm story of five people who met across time, finding the "meaning of life" and the "feeling of treasuring someone" within their limited time together.
