What gem, Gem Weapon and where would the gem be on Kounosuke?
Before answering: shot-out to pal thefortressofscience and my boyfriend juuichi-da-bear, who helped me with it. See, I know *of* Steven Universe, but I have only ever seen bits of it. So these two lovely people helped fill me in on the canon… If I got it wrong be sure to tell me, please!
Between the shoulder blades.
He can turn his glasses into a visor which lets him see “beyond the immediate”. For example, he can sometimes see the monsters original gem form and even bring them back with compassion, a la Steven himself. They are usually worn as glasses, which he doesn’t really need but keeps them for that reason.
That sound good?
EDIT: Shotout to shanghai-ohmy, too! Sorry I forgot to include you on the first round, man!
