Looking for a historical/ romance manga where the main character is a young blonde orphan girl taken in by an older lady who obsesses over her son. The young girl dislikes the son and wants the attention of her adopted mom but is treated like a maid. The son eventually goes into the military and from there romance between the two in secret happens

Looking for a manga I read around 2015ish I think. It was a young boy as the main character, him and his people had tails/braids coming out of their head (almost like a pangolin with the scales) and would use that as a weapon. They were in hiding from the main villainess that took the form of a spider and has a lot of henchmen. The people were in hiding so they could save the saintess who kept reincarnating (she was a child with white hair and pale skin) and dying at the hands of her evil twin spider sister. The last part I remember is a lot of the family dying to save them and make sure she defeats her sister along with the little boy. I want to say this was an early or late 2000s manga.
