Just went through the current Ken route and everything was fantastic.
The music, the starry night sky in the backgrounds, the character designs, the story from start to finish was engaging and a rollercoaster of emotions.
Ken himself is just perfect. Both visually and as a character. He's not your generic, dangerous-looking, perfect boy with no flaws. He's damaged, his dark past shaping him into a person he has to be now instead of being the person he wants to be. The conflict between the two is a great way to develop a character. It's also a great way to get the reader interested in the character and crave for more.
That's where I'm at now myself. I can't wait to see so much more of Ken and where the "road" will take him next.
Oh and one last thing, Nikko's art style is a blessing for the eyeballs.
