User blog comment:Sebun Gousuto/Previous Seven Ghosts generation: Cliques?/@comment-5714639-20130523213427

Rather than the 07-ghosts being divided into cliques, as a whole they seem to be a clique of their own. By definition, cliques are composed of close friends who share the same goal (protecting PB, destroying Verloren, etc.), and within cliques every individual is different than the next, either in terms of personality or physical appearance. And because everyone is different, there are bound to be those who are closer with some members more than others.

Ea and Landkarte are the same age, which makes them peers, and therefore more relatable to each other, as rest of the Ghosts are much older than them. Naturally they would enjoy each other's company more.

Vertrag seems to be more interested in keeping his country and family safe, which means he doesn't really spend much time with the others as he's mostly within Raggs country.

Zehel appears to be "the loner," the rebellious BA who does whatever he wants, regardless of rules and social norms. Although he likes his comrade Ghosts, he doesn't mind if they're not around - he doesn't need them to have a good time. Like Vertrag, he's also often away from his fellow Ghosts, as he's a sky pirate and it takes up much of his time.

And, as you've mentioned, Relikt, Profe, and Feste seem to be a trio of friends who enjoy each other's company and have fun with each other. They are the most social of the Ghosts, and are very friendly and open with strangers.

But as I've mentioned before, they are all part of the same group and share the same goals. Just because some seem to be friendlier with each other than others doesn't mean that they don't like the rest of their comrades or that they've separated into different cliques. Just that they enjoy being in the company of some comrades more than others.

At least, this is how it seems to be to me.
