I'm sure this arc is going to end in at least a semi-tragedy. I suspect Chrono is going to "die" in order to save everyone else, but it will be a sort of conditional death, in that he'll be in a state of reduced power and consciousness, and locked inside Ichi's Magic Circle (having been acquired by Ichi). This will plant the seeds for Ichi's long-term goal of completely overturning the natural order of the world involving humans and Magicks, so they can live side by side someday. Idk. Something like that.
