I was able to accomplish this in ~15:30.
I picked The Bone Zone level.
I started with Endless, Aracana's and Limit Break.
I started with IV- Awake for the revives, just in case.
Aside from his starting weapon I immediately bought Cherry Bomb and La Robba from Glass Vizard.
Then through level progression I chose the following:
Weapons- Night Sword, Magic Wand and Laurel
Passives- Empty Tome, Spellbinder, Duplicator, Torrano's Box, Crown and Skull o' Maniac.
Skull and Torrano's Box specifically for enemy spawns rate, because both are cursed along with Night Sword.
Popped around 15:26 mark.
Good luck and happy hunting.
