The Showa era—a time when war was a part of daily life.
Young men were tasked with the mission of fighting for their country, sent to the front lines leaving behind their families and loved ones.
Among them was a soldier whose day of deployment had finally arrived. He didn't know when he would return, or if he would return alive at all. Even so, not wanting to make Guest anxious, he smiled as he always did and said, "I'll be fine."
Knowing this might be a final farewell, or perhaps a day to meet again would come...
