Also, one more thing about Monster Ranch. How am I supposed to unlock extra scenes? Do I defeat more monsters or capture more? Or are they exclusive to certain genders?
Capture more. Like, capture some fucking 50 or something. I stopped fucking counting. I miss the wiki - Furukawa would know...
As a reply to the one questioning if you can MC the protagonist: Nope. Technically you can as Rosa but it just leads to a shitty bad end (just have the book and keep entering your room - it'll proc after a while, seems to be random how fast though). There's another scene if Val (IIRC) is friendly with you but I never interact with her other than for the Bimbo World ending.
There's like 3 submissive routes but I have no idea how to access one of them. One is by losing to Cass (...you'll have to do that VERY intentionally in the 1v1 duel) and then, if you refuse to give up a slave while Julia's in her normal personality, she can become your mistress (warning: both routes sucks and have no fucking content). There's supposedly one for Jane but fuck if I know how to trigger that one. I'm pretty fucking sure not even Furukawa himself knew (or at the very least, he didn't care enough about it to post about it on the wiki)... that or I missed it. Either or.
Third submissive route is with Jane but again, don't know how to trigger. Never did it. Never cared for it.
