Oh I forgot to mention, the Shiki stuff was pretty cool to see animated. Isolated it almost could look like he's the main character here.
Shiki's power
I don't think this is a spoiler since it all happened in the past but it's cool to note the rings he used were the rings they gave him to try to make his mana barely comparable to Makoto's, which then became part of him. I can't quite recall but I imagine 13 steps is related to each ring, I think I vaguely recall them saying something like double up rings on his fingers because 10 wasn't enough.
I can think of Forspoken and Deathloop
