It's been quite a while since I've played a Sho Minazuki joint, but I maybe end up joining. I like the stat system a lot, and fantasy meeting modernity is one of my favorite settings. Before I start creating a character though, I had a few questions about the system.

Stat cap raises-- are the costs cumulative? For example, would it cost 70 points to raise a stat from N/A to D? (I.E 10 (F) + 20 (E) + 40 (D)) Also, Luck's effects are not described. I was kind of thinking of a character who's best stat is luck, what would that look like?
