6 months and people still don't understand the PV?
Though, this never happens in the story, in the PV the Laws only target is Exu, not Lemuen or PL (hell that wouldn't even make any sense) or Doctor. That's why he's constantly focusing on Exu in the PV and ignoring Lemuen.
I guess the implication is the law wants to stop Exu from reaching it. Funny considering in the event the Law wanted to stop Executor, Andoain and Arturia from reaching it, since they were the ones trying to stop it.
