Kingdom Hearts is a series of crossover action role-playing games owned by Disney and developed and published by Square Enix.
Kingdom Hearts used to be shy when first meeting people due to his lack of memory. Even now, he still hides his face using his hood whenever meeting new people. He has a tendency to appear out of nowhere, not realizing that most people don't expect it. His stature and appearance when he appears set most people on guard, though Hiro is usually harmless. When not in a fight, Kingdom Hearts speaks softly and without many expressions. It takes a lot to excite him, though some people are more likely to excite him than others.
