Didn't see a thread for this manga (if there is I am truly sorry)
I had already seem it along time ago but only now I had the time to read it
So here goes a brief Description
Yugo Beppu is a master negotiator and mediator. Fluency in five languages, Socratic wit, and a deep understanding of human nature combined with top-level international connections make him a formidable operator. When a woman's father is seized by Dacoit bandits in Pakistan, Mayuko seeks Yugo's help. After complex and dangerous negotiations, he secures his release. After this success Yugo is called in to deal with yakuza in Japan, triads in Hong Kong, the IRA in Northern Ireland, and the Russian Ministry of Internal Affairs in Siberia.
What make me like this series is it's got realism, humanitarian traits and it has lots of international issues, such as war, politics, mafia, kidnapping, religion, human-cloning and social status
