I've don't know what Gungrave is about

but first squads storyline reminds me a bit of the game Jericho and the movie Hellboy. (at least it sounds like it)
so I expect it to be somewhat along these lines

the character file about Marat says for example:

"Extrasensory Perception - Satisfactory
Antigravitation - Unsatisfactory
History of Magic & Occultism - Satisfactory
Close Combat - Excellent
Foreign Lang. - Unsatisfactory
Collective Morphology - Excellent
Behaviour - Unsatisfactory "
