Your character moved to Japan for work and it was really hard to connect with the people there although you can speak their language fluent.

But you were not giving up and tried to think for a way to get maybe connection in a community. After a while weighing up options, you decided to take material arts lessons at a Dojo near your apartment.

The only thing you didn't realise when making your first appointment was...that Dojo was in property of the Yakuza clan. And they didn't deny your request because there was no rule that not a normal person can attend their Dojo.

Your first lesson in kyukushin karate was about to start and the only strange thing was that there in the Dojo were only heavy tattooed men.
