That one sounds interesting too, I'll check it out!
I also really enjoyed To the Stars (currently on ch50). Especially the beginning where most of it is fleshing out the madoka lore in a uh, comprehensive way. Like it seems well thought in how magical girls are integrated with science / the military / the govt. In terms of characters, not sure I really care for the SoL scenes but I thought each of the ancient's backstories was pretty interesting (I'm sucker for tragedy).
