Vendetta Ignited (SF9 AU)

A vengeance for his murdered family. A reason to live even though it feels like there's nothing worth-living.

He never knew he will live a dark life. Forming an underground organization called "9th Base" and leading it at such a young age to be called the 'boss', he was able to gather men with high quality of skills and talents on their respective fields. He has a supportive best friend who has a whole family supporting him and a trusted advisor. They became his trusted men and together they will chase whoever needs to be chased.

All we know about mafia is illegal activities, underground transactions and dirty killings. Once you enter their world, there's no coming out--unless you die. You will never want to cross their lives and stuff, you can't make anyone of them angry.

For the men who joined 9th Base, why did they choose to live this way? Are they really ruthless, merciless and heartless? Don't they really care about anything in life but themselves?

Does love make any difference to them while living in their dark fate? Or will it make their end worse and much faithful as vengeance, violence and death are on their door waiting the moment they joined in?
