Out of nowhere.

The full moon is exposed in the sky with no clouds covering it, Sando is walking on his own and then he notices that so many people are walking into the dark alley not far from in front of him. He stops walking and looking at the alley and keeping an eye on the people that are walking into it, he notices that most of them are having tattoos on their hands and chest, he knows that those people are yakuza and not only them, but a lot of ordinary people wearing t-shirt or shirt and a suit are also going into the dark alley. He's curious about it and so he decides to go over there and see what's inside.
