The principal said in chap 38 that she broke the taboo and had rapid growth, so maybe there's a rule in this world that if you have sexual feeling before coming of age, you'll die from pain of rapid growth? (it sounds like cancer tbh 💀)
Funny how the creator of Haniel diss anime adaptation since it will never capture her beauty then Fukuda-sensei made this chapter to "kinda" prove that :V
I just added this 2 days ago hoping by the time i reached the lastest i'll get an update but i didn't expect it to be this soon! Thanks for picking it up again!
Shinki remember nothing from their past life, if they do, they'll get trauma trigger (mostly because of their deaths) and become monsters. Yukine never had memories of his past, and he turned into a monster when he recalled it. So now Hiyori will also forget all her life. :(
