I think it’s just too early like by telling Kurokawa it’ll probably lead to her getting all confused and start getting overtly conscious about anything she and Takahashi together. So I think it would be better if she’s come to realize it herself/naturally.
Tbf what he does after saving saving the heroine should be accolades enough to secure his spot. Plus Allen has already single-handedly captured multiple other forts before this as well I’m pretty sure.
Damn the witch is still alive though that seemed pretty obvious with how they focused on her head so much. I’m betting that big bad wolf guy probably has some kind of time restraint on his strength or something important to him which is why he decided to pull back.
Why didn’t he just take a photo of his map as he updated every now and then to make sure something like losing them all wouldn’t mean complete loss of progress. At least then he could just copy it all down again if the map was damaged or lost
