he has so much trust in roses abilities that he even risked making the first move on a hitman who is on par with rose...
the two were careful around the bear but they really didnt expect an acorn to fall and wake the bear instead
it was for they couldn't get the first move/advantage and he expected to get beat in the first place (thus is why he didnt ask for strength when he was praying and instead asked for strength to go to rose and benika)
what he said to rose before the attempt was to tip her off that hes aware she is a hitman and shes going to need to act now because hes going to make the first move and give her a few seconds to defend benika and the rosary
I'm gaining a small crush on the dad. He is fine with his daughter dating another woman, still wishes them happiness even after he finds out Rose is an assassin, and is capable of finding out what those two are up to. His only mistake was underestimating their power
I'm going to miss this manga when the final chapter comes out...
