Just Passing by Muscle Beach (Patreon)

Again, another one I'm not sure if it would make more sense as a three-panel comic.  Nani the ninja is super-strong for limited amounts of time.  I thought she might be wondering around and decide to test herself.  She doesn't look like she's really straining because this probably isn't near her limit.  This took some effort, but it's not a strain.

I was going to put something on her shirt, but I couldn't think of anything that didn't suggest she wasn't just there by happenstance.
