That last page, I was thinking there's no way someone would speak like that, suddenly introducing themselves to someone they already know in a dramatic fashion, but then I thought again:
"Try telling me, for I am Elon Musk."
Yeah, that actually sounds like something that would happen all the time in Elon Musk's office. I'll give it a passing grade.
It's a common trope in JRPG's for 'cursed items' to simply be unable to be unequipped. They sometimes have other negative side-effects, but not always.
