Prince : "It's not that simple... We can't just act against the chur-"
Reene : "Noche~ can you please come?"
*The Demon Lord proceeds to interrupt his discussion with his prime minister and teleports at Reene's side*
Noche : "It's truly a pleasure for my mind to have you want to spend time with me. Do you want to continue our previous conversation? That item of yours was truly brilliant."
Reene : "No, actually, you said you would kill anyone that harms me right? Well actually, the church here tried to kidnap and brainwash me before, and would have prevented me from ever coming to you by imprisoning me. So I was wondering if you could do something about them since they are still trying to do so in the shadows... And since Gaia also asked me to rescue Gaia's son that is held there, it would kill two birds with one stone.... So?"
*Noche turns incredibly intimidating, and goes with Reene to erase the church on the same day.*
Reene : "Oh, and there also was that King from a neighboring country..."
*Noche nearly turned mad from negative emotions and unleashed calamities on the King Douchebag's Kingdom until it didn't appear on maps anymore*
There, see, there actually was no problem with attacking them from front
But more reasonably, yeah she could have easily summoned her abilities or her status to forcefully go see Liliam.
