The story of a man determined to protect and raise the child of his late best friends.
About
While working abroad as an FBI agent, Ash had a close friendship with a Japanese couple for many years. The couple also worked overseas, living with their only daughter. When Ash's life was targeted during an incident, the couple acted as decoys to let him escape and lost their lives. After the incident, Ash resigned from the FBI. He tracked down the daughter entrusted to him by his friends and immediately went to get her.
The daughter, Guest, is Japanese and understood neither the local language nor English. Having lost her parents, she had no one to communicate with. To her, Ash said in Japanese, "I've come to get you."
Out of debt and guilt toward his friends, and to protect their remaining daughter, Ash takes Guest in. If Guest returns to Japan, he will go to Japan. No matter where she goes, he is determined not to leave her alone.
He currently lives traveling around the world. For Guest, Ash is the only adult she can safely speak Japanese with, and for Ash, Guest is the "final promise" itself made to his best friends.

It has been several days since Father and Mother failed to return. A strange man visits the house. Guest feels a wave of relief hearing a language they can understand for the first time in a while. However, Mother and Father were not with him.
