The redhead's sister is already shown & I won't be surprised if the blonde has family members too.
This is not a in your face race superiority game. The main plotline is about the MC's inherent supernatural superiority (rulership) to everyone & the raceplay is only ever done as a kink.
Tbh I prefer this over those blacked games who think having a racist black mc surrounded by white chicks is all they need, ending up with a subpar game only enjoyable by hardcore fetishists willing to ignore the negatives of the game to enjoy their kinks.
(to be completely honest, kinda the pot calling the kettle black as I also often do the same, all the while criticising characters development, game structure, etc. & just looking at only the (my kink) scenes attentively 
)
Cause the game isn't really racist. The only racism in game is from Karla, who is a victim of child abuse & brainwashing in the hands of her cultist mother & thus
krazy (love her character

)
The main plot is about the MC being the chosen one, a sacred bloodline with white eyes. The MC is decent & definitely not racist or toxic. He only goes along with Karla's fetish cause he likes her, along with his father's creed cause of guilt/respect & along with 'toxic masculinity' because the instance proves & justifes it to a degree.
In the beginning we can see his subtle attitude to his father's memories about race, 'toxic masculinity', etc. As the game goes on we can see his subtle shift as he starts following his father's creed & his powers/personality develops/changes, shaped by the events taking place due to him following the creed & acting as such - still subtly instead of becoming a racist 'alpha' jerk suddenly.
So despite the game featuring 'bleached' as a core kink, it's just a well done novel with good world & character building, containing nothing ban worthy.
Hence I'd also disagree with Demoness_Kiss about putting this in the same level as the generic, mass-produced & formulaic blacked games & with panzermaster about putting the kink in front of the overall plot & character development.
Racism
is bad, however what's more criminal is how many substandard 'blacked' (possibly some 'bleached' games too, I wouldn't know) games thrive on using it to survive.
As a neutral player who doesn't have a preference either way, this is a well done game which isn't offensive if someone actually plays it & has a brain. Only complaints you'll get are from ppl who just look at the OP & complain, and ppl who can't understand complex character development like MC & Karla & the difference between 'racism' & 'raceplay'
Kink structure as I see/guess:
So it's just a good VN exploring bleached fetish in a great way, with no blunt racist overtones (except Karla, but she's shown to be a victim, her mother will probably be evil/shitty & the resisting sister just completes the complex family dynamic - very well done imo)
Just very well done with a potentially controversial topic.

Pretty sure the dev would explode if they went with a safer topic.
Then again, I see the success of games only catering to kinks while well done games don't catch on, & I hesitate to bet on my idea
