9999 kills doesn't get you max powered catalyst weapons, not even near that. 999999 is most likely the number of kills which maxes your damage.
Here is a video of someone with (probably) maxed out kills http://movie.enjoys.jp/view?NgX9Rw99Fqk
Final boss should take around same damage as those since defense doesn't seem to affect much on catalyst weapons. My Anise does 500k with normal attack on first enemies on normal and same to final boss on unknown.
Besides having the number, what's the point in inheriting Arte Usuage?
To clarify, it only allows for faster Artes at 999 uses. Also, the Arte Usage is a semi-novelty to see how many times you used an Arte, and also effectively eliminates the need for you to use crap like Raging Blast fifty times.
And it could be me, but I swear I already corrected Blaze_Returns on this...
Is it just me or are the japanese voiceovers way better than the American ones?
Way better is an exaggeration, and outright wrong for a lot of the cast. JP Tear sounds like she's trying too hard to be cold, IMO. --- Don't know what to put here yet... # of people I've seen who haven't read the damn board stickies since 2/13/08-10(Booo).
