Persona X Steven Universe
When Yu Narukami had decided to open up a Coffee shop in the quiet town of Beach City, he'd expected the ocasional curious local to come visit during his first week open.
What he got instead was broken Gems in need of a safe place to just let themselves grieve and break down, away from the people they're sworn to protect.
Naturally, Yu is determined to be exactly what the Crystal Gems(Little on the nose, don't you think?) need, even if that means throwing himself into a galactic conflic thats been ongoing for thousands of years head first.
If only Ruby, Ragna, and Hyde could see him now, they'd probobly be right their in the thick of things with him, smiles on their faces and weapons swinging.
