271 chapters and you still think there's logic to this series?That was stupid, This could have been another Armour Prez/Dancing Prez, so why kill it before opening it. The fact that he finds a corpse inside, well... DUH!! she may have been alive 30 seconds ago you dolt! This was a serious failing in logic from the writer.
I think it was a combination of effects, the living armor has a curse that binds it to your flesh so it can't come off, the ring reverses luck/curses, and the lich's jewel gives you immortal undeath. So, when it was all reversed by the ring, the armor gave her flesh and the jewel brought her body to life.Back in the days he made Angelica wear a slain Living Armor when she was still a pile of bones. That thing transformed/adapted to her so she had some sort of shell. Later he gave her some items. IIRC it was a ring that brings good luck and happiness, a bracelet and some necromancy jewel. If I'm not wrong, the bracelet completely destroyed the curse she was under and the gemstone had control over life and death which is what gave Angelica a flesh and blood body.
That much is for sure - ah, by the way, found it: the artifacts and effects where mentioned earlier but in Chapter 60 it's explained what actually happened. Leaves the question, if that's Angelica's original body and if so, could she go back... or rather, would she even want that? She seems to be quite fond of her new, artificial body and her connection to Haruka.I think it was a combination of effects
