No, it is Officer Leon who was chasing D. The D Chris found is the father grown up. Remember when the father got shot, died, then became a baby to be raised by the grandfather character? Yeah, that's him, all grown up as a brand new person (while the dad was the new characters origin he does not have those old memories. it is truly a reincarnation, he is his own person).
REALLY?! both count D’s look terrifyingly identical so it was hard to tell but i believe u on this!
if you want to see more of D there's a sequel. It's referred to as both Pet Shop of Horrors Tokyo and New Pet Shop of Horrors. Both will get you to it. Assuming you haven't started on it already, that is.

Chris said Leon went to pursue D to return something.
My guess is that D finally let him ride the ship / pet shop with him.
And Chris met either D's clone son or his reincarnated father.
i really thought at the end that was leon who chased count around the world in each chinatown (technically he did?) and finally reuniting.....and then finding out that’s chris all grown up! if that’s 20 years later that makes him around 26 years old, meaning leon is already 44-45 (they have an 18 year age gap) like bitch i’m kinda sad??? as rude, crude, and annoying as leon was it’s like i wanted him and the count to be together. they looked like they had fun together at times
