Yes, I do have a recommendation if you want to explore the game:
Sachiro - Easy to start off and mild complexity
Zeikun - Linked with Sachiro
Junoru/Kurato - both are plot heavy
I recommend not to start with Kurato but after completing any other route. There are a few scenes that only unlock after you complete another route.
Even if you play a different order, it's not a problem. In the end you have to play all to understand the whole story.
