Plot/Story
Yugo's story ended each negotiation, so sometimes we just named each negotiation with the name of the country he visited. Such as Pakistan arcs, Russia arcs, India arcs, and so on. The story involved politics, radicals group, humanitarian issues, etc. Every mission started when he agreed to help the clients. But not all of them have good motives, sometimes Yugo agreed to help them because of his own believed.. Not for the clients, but for the victims/hostages.
Characters

He graduated from psychology major, master multiple languages, deep analytical mind, strong will, good senses, and has high persuasion skill.

Drawing Style
The art is clean, not messy, and also good details. The characters drawing are good and distinctive. Detail background, such as landscape and buildings.
Enjoyment
I can't say that all of you will love this series. But if you are looking a good seinen manga, cultural-historical, political, humanitarian, international issues, and type of detective stories. This one it is.
Overall
It's very good in term of story, characters drawing, and detail arts. The creator and author of this series did a lot of research, including field research to the country which the story took. Everything just to make this manga.
