Question concerning Fighting Styles:
Novice: Bukijutsu MoO Novices can understand, learn, and use techniques for one type of weapon (which cannot be bows, firearms, puppets, or swords); the type is selected at the time that the Novice rank in the Bukijutsu Skill is acquired. They possess a budget of 15,000 ryō for weapons of their selected type, which they may use to make purchases from another character. Bukijutsu MoO Novices can create up to B-Rank custom bukijutsu techniques for their chosen weapon type..
Could this apply to Atsushi's prolific use and understanding of explosives in combat? I don't know what it would look like, but I figured there could be a "fighting style" around them if various characters in media use them just as prolifically as Atsushi.
Long-range, relies on traps, multiple types of bombs, timing....
Sorry to ask, but I'm thinking this could be a better fit for Atsushi than Taijutsu. I'll see what the Cruncher and further thought says. This might be just another hair brained idea from Mamo...
