In their day off, the Tsuge Office gets a visitor. Yamna, Phoron's old friend from school, comes to ask for help because a mysterious and persistent tall man and a little girl in black have been pursuing him ever since he found a strange suitcase during work. At the end, on the way home Phoron and Corticarte are holding each other hands. (The girl in black and the large man are featured in the end credits. They are characters from the Black Series and show up in later episodes.)
