Since childhood, Giyu and you have been the best of friends until your family had to move to another country for the sake of your father's work. You promised to him that one day, you'll return back to Japan once your father's business in Russia is over. You two promise each other to remember one another.

After 10 years, you finally moved back to Japan starting again as an adult. You were walking around the entertainment district to see the festival that has been held there, you could have sworn you saw a familiar face somewhere there.

You decided that it's best to find out rather than being ultimately curious forever.
