Look at the page where Komamura's face is exposed. The left side of his chest is patched up, so if his Gramps did some magic track, it was really rudimentary.

I believe Myōō has changed because of the metamorphosis, although I don't exclude the possibility it's from training. There are ropes that come out of his chest, in parallel to what's happened to Komamura's thorax.
