Relooked through the mod files (at sounds) and this is what I can see:
"Aware of inappropriate female anime sound,better try with earphones first" While not exactly true it also isn't false. It's a mix of scream-moaning if that makes sense. It's not as bad as, say, the Girl Zombie mod but it just seems out of place.

The male sounds actually sound like they would fit in. Unlike the female sounds the ones the male makes sound more natural and less out of place.

TLDR: Female sounds unnatural and slightly inappropriate and the male sounds fine.

Sorry if this came out as rude I'm half asleep after pulling an allnighter

@Invader you're right, i didn't notice that mod and i just feel the sounds from the mod in the link were weird. I will edit the link to direct to the true original mod and declare this mod is a anime voice pack

Wasn't this "Screams of Pain" mod? Or is it a different one?

@EagerPlanes341 Yes, i don't know why the original author use them, i'm still looking for suitable sound for male and will be finished today

Looked through the files.
The sounds are odd.
