So.
For some reason people keep asking how to get Cheev Mants as if there's some esoteric mystery method or it takes forever, and the only way that's true is if you completely ignore the character creator, and even then this is the simplest progression an Illusion game has ever had.
R8 H8 M8:
Sadistic
Loathing
harsh
Hates Sex
2 meetings should do it, and you don't even have to sex them at all, just have a bad conversation or two and you're done.
Horton Hears a Hedonist:
Open hearted (this is a monster mistranslation by the way, the actual connotation in japanese translates to UltraFuckasaurus Rex Maximus, not "free spirit", this personality is not a hippy, she's an urotsukidoji endboss.
Perverted
Willing
Horny
Now you might think I've lied because this chick just ain't into you and it's going to take forever, but the first time you do some freaky sketchy shit with her and get away with it, that :| face will instantly turn into this face:
You must be registered to see the links
you've been warned.
Miss Slave:
Quiet (again another hella mistranslation, the term Docile is far more accurate)
Willing
Obedient
[ANY]
You too can watch your waifu insert Paris Hilton in one gulp in three easy steps.
The Magical Menstrual Misadventures of Captain Co-Dependency:
Timid
Glass Heart
Lovestruck
Lonely
This one is basically 50% dramabomb and 50% trainwreck as the waifu in question will do the following: Max out love DING -> Max out Desire DING just from conversations or simul orgasms-> Actively chase the player down repeatedly DING and "attack" -> Max out Dependency DING chasing the player literally through the halls -> react to any forward or sketchy action with NOTICE ME SENPAI DING -> Broken state DING from not being able to find the player whom is now hiding for their dear life and with 3rd degree friction burns in Fur's hat, which will speed up her event DING. Literal Achievement Pinata.
Most of the rest should occur with interacting with these builds.
