Looks promising.
This will be another long adventure after take a leisurely stroll in RINNE. So, I expect a lot.
Maybe I would not recommend this if you are fed up with this type of adventure in eradicating Ayakashi because I can find similarities that might be reapplied here: strange creatures with strong spiritualism, two interconnected worlds, etc.
The basic personality of the two main characters looks good. I really like characters who are not noisy - well, not really, because the female lead is quite energetic (in a good way). Even though she now has a strong, tough character - I haven't seen what action she will take about her condition. I hope she participates in conflict without being made like a useless, weak girl .. like, you know. And here she is paired with a cool and serious male lead. Let's see where and what are the main problems that connect them to work together.
This really gives a good impression. I'll give a rating later.
