After seeing the untimely demon invasion, Alex needed the plan to benefit from it, and seeing that none of his preparations were completed, he only had one option left, and that was to use his Ruler status.
Alex understood that any harm he did to the demon, which purely came thanks to his status as the Domain Ruler, would break the restriction placed upon him by Zero, but he also understood that those restrictions didn't work in special circumstances.
After some thinking, Alex devised a plan to get what he wanted without hopefully triggering the restriction, and to accomplish it, he took help from his trusted guardians in the form of two specific unRanked Scroll carrying the power on par with the Seventh Rank spells.
