Seiji Maruyama is a middle-aged yakuza recently released from prison. Known as "Gozuki" (one of the demon generals from Buddhist mythology) he is the power that his oyabun counts on. But there is one thing his aniki is not taking into account: Maruyama is getting old.
You can skip a scene if you have seen it already (keep in mind that since it's just implemented, the game doesn't know what you have seen up to this date). Some scenes are unskippable (scenes with choices mostly).
If a scene is skippable you'll see the icon at the top right corner.
