Hey all, after fruitlessly looking through the past 14 pages of posts here, trying to guess the name of this anime I am looking for... I am finally just asking for help
What I can remember: the scene took place in an old church, or tomb or something dark - there were a number of characters and it preceded some little battle they had. I believe there was a female protagonist protecting her male classmate (?) very flashy/magicy. The actual TG was another character turning out to be an android or doll or something, and changing into a girl. I believe there was a scene of gears shifting/interlocking as well as an excellent breast growth scene. I thought it was more recent, but have had no luck just scrolling through crunchyroll trying to see if any of the names job my memory.
I realize that is not a ton to go on, but any help would be SUPER appreciated!
