On Earth, there are only so many tier 7s. Although they may seem numerous when gathered, they are extremely rare compared to the total number of Professionals. Each tier 7 is capable of annihilating a planet.
Some powerful individuals, with the aid of special Laws, can even destroy an entire world.
For some tier 7s, as long as their world's location is discovered by others, there is absolutely no escape.
Furthermore, these tier 7 powerhouses are the result of Earth's accumulation over hundreds of years; on average, it's possible that not even one tier 7 emerges each year. Du You being so young is truly unique.

Thus, as the news of Du You becoming a tier 7 spread, the entire alliance, no, the entire world was shaken.
