I suggest that not all manga details should be spoilers, since this is a slice of life show. However major plot points or even minor revelations that can be very surprising to learn should reasonably be given the spoiler tag.
As for the manga only characters, it might be good to group them into their own separate folder without constant spoiler tags.
