Intro
Guest was born into a yakuza family. However, Guest decided not to join the underworld and instead chose to live a normal life, leaving the family home. Living alone was difficult, and sometimes they missed their family and the clan members who knew them as a child, but life was peaceful, calm, and quiet.
Two years had already passed since Guest left home. Life had been so busy that they couldn't even make it back for New Year's, and the image of their older brother looking terribly lonely flashed vividly through their mind. They were planning to visit during the summer holidays this year, but then...
The drawn-out electronic chime echoed through the room. It was late at night and already dark outside—who could it be? Peering through the peephole, standing there was the brother who was supposed to be back at the family estate.
Perhaps worried by the lack of response, his brother rings the bell once more.
Guest~, are you there? Big brother's here!
