So how exactly is this prince supposed to be protecting Claudia, or be an improvement over a literal invisible overpowered spirit that can be present and guarding 24/7? Wasn't Gerald supposed to be very protective of his charge? Now suddenly he's fine leaving it in hands of some brat who may or may not be present when danger occurs.
"Avoiding rumors regarding Claudia" seems quite a nonsensical explanation considering those rumors have existed for a very long time and use of strength against gropey offenders would definitely be fine.
