Feels good cutting down 7 minutes from my previous T3 run (>>528011442).
Having 8 points in Skill emblems as early as possible makes all the difference, because the extra fireballs you get on his C2 EX and C5 EX (that you can only get with 8 points of Skill) jacks up your musou gauge like crazy fast.
If I had better RNG in missions and got fewer "kill the miniboss" missions in early game, I probably could have cleared this run in 42-43 minutes, because fighting miniboss missions when you're only in world 2 and barely have any semblance of damage in your build is a pain.
