Well, we can also highlight the "struggle between light and darkness" as a possible clue... So, who could fit that description: Lizard with the clan emblem...
When in the deep darkness of night
A lamp illuminates the room,
Not only in the working room,
But also in the heart, as if light is spread.
But somehow I don't believe he's the Mafia... although, of course, anything is possible... :o
