Probably because Angela was the weakest and least fun character to play in the original. Now that the remake overcompensated her into the strongest, she finally stands a chance.
Not a great chance since half the reason Reisz caught on was most doujins treating her like an OC. Trials' writing is so nostalgia-shatteringly awful, decades of forgetting the source material only helped her. It might be too late for Angela to hit that sweet spot but at least she got a lot of fanart and nude patches.
