Since the two World Wars, the Transcendents had signed an agreement to prevent excessive conflicts causing major casualties among themselves and ordinary people, which prohibited the display of Supernatural powers in front of ordinary people and the use of Legendary-rank forces within cities. However, an agreement is only acknowledged and followed by everyone when it's needed and recognized by them.
This is like the so-called international conventions, which are deemed as international norms that must be observed when they serve the interests of powerful countries, but are treated as worthless paper when they do not.
Powerful countries treat international conventions in this manner, and Transcendents treat so-called laws in the same way.
