More Enemies
"More Enemies" is a hidden tag for certain Items. It's applied to items that increase the number of Enemies that spawn, which increases a wave's difficulty, but also increases the number of materials that can be collected per wave.
The Character 
Loud has a higher chance to find these items in the Shop.
Two item tags that decrease enemy difficulty also exist: Less Enemies and Less Enemy Speed.
