Kent, of course, chose to reveal his true self to Yuyin since she is Liora's aunt.
However, as for whether he enjoys seeing the shock on the faces of all those he reveals himself to, the look on Yuyin's face at the moment answers that.
It amuses Kent whenever people learn his true identity and become shocked. Of course, he understood that his existence, to many, is profound. However, as time passed, he expected them to at least relax a bit when learn of his true identity.
But since they always go through shock, he can only enjoy it and hope that one day his identity won't make many people's jaws drop.
All those after him with nefarious intentions, of course, have to wait until he reaches the immortal worlds. He had not yet done anything drastic to them... well, Uncle Drew did a number on them.
But Kent had yet to handle them. Of course, he also knew that going after them would be bullying them at this point. So the immortal words will be the best place to handle them.
