Well SIU didn't tell us anything about this (as far as I know) but I believe it has to be Zahard (or someone in-his-stead) that conquers the floor with a guardian test to include it inside the empire.

Because if an irregular just passes the test and climbs to the next floor without special agreements, it won't unlock it to everyone automatically.

In my humble opinion, if Enryu didn't kill this guardian, it has to be pretty damn strong. I can assume Zahard and the Ten Great Warriors wouldn't try to kill it because they'd lose a floor, I doubt Phantaminum would need to attack or kill it (he could destroy the whole world if he wanted to, word of god) and Urek seems to not care about it.
