This makes me wounder if Homura didnt actually make her sight better, but actually just heal them to how they were before. Most people now a days only have glasses because it worsened with bad habits.
Although I'm not sure if curing her heart disorder is actually regeneration. It's not like she had an infarction as a child.
Homu!Homura-chan is so cool!...and improved physical ability and tolerance!Recovering vision with Soul Gem...The limits of Soul Gem...my chest won't get bigger?That's obviously impossible.
