I don’t think they’re related and since a lot of people are thinking it’s incest probably because of the poor translation so it’s probably like jiao is a child of Lians moms friend who died and she took her in to raise her so it’s just not incest idk why they added some weird translation to make it seem like that

From what I’m understanding from the entire manga and some spoilers I think wakaba could possibly be “D” hence why that black knight dude said “she is oddly similar to D” and probably because it is her but in the past but at the same time I don’t get how because her soul got reincarnated here as a spider and ascended to like a god like also become a administrator but D is able to talk to them which is weird because they might maybe have split souls but I don’t think it’s possible or could be as long as more chapters are coming out translated keeping up with more of what happen to them

Basically our MC has a soul of a spider (in the classroom) and Admin D's memories. Remember in the anime Admin D said she was in the classroom and didn't reincarnated? She was the girl with long hair and long bangs and she didn't reincarnated due to her being an Admin (their term for gods). And didnt Admin D said that she reincarnated the students to species that match their soul wavelengths? Well our MC has the soul of a spider and Admin D's memories

What they meant was that in the classroom when everyone died, MC was a spider just chilling in the ceiling but happens to get caught in the reincarnation cataclysm. So MC was neither student nor human back on earth, just a spider. And D planted her memories and identity to MC to make her and everyone think "Wakaba Hiiro" reincarnated as well. (〜 ̄△ ̄)〜
Ngl seeing sayaka and Kirari relationship being strained like that kinda hurts ngl although it doesn’t look healthy but I can see that kirari actually cares for her during those few bits of the new chapter and also how she also covered her with her own jacket
