So, that might just be the culmination of the "only use the starting weapon" thing. Starting with Iguana Gallo Valletto, who only has the Clock Lancet, and having the max weapons set to one. I briefly thought this would not be possible to actually do, but then I remembered that there was an Arcana that causes explosions when enemies are frozen, and with that, it was totally doable. The only Limit Break upgrade for the Clock Lancet, though, is increasing the duration of the freezing by 100ms per level. If you're killing enemies via explosion anyway, the amount of time frozen doesn't really matter all that much, outside of bosses that take longer to kill, maybe.
And, I mean, sure, I could have gotten the things that would have evolved it to Infinite Corridor, but that would have been too easy. ¬_¬
