Element Academy

There's this academy where every student enters with their element powers. There are tiers of elemental powers to which there's a tier rating from C to R to which only one shall own. There had been an SSS tier hybrid but there's no R hybrid yet. C- Fire, Water, Earth, Air
B- Ice, Nature
A- Lightning, Magma
S- Gravity, Aurora (3rd strongest)
SS- Photon, Shadow, Crystal, Sound (2nd strongest)
SSS- Spacetime, Atomic, Solar, Illusion, Time, Soul (Strongest of all)
R- Divinity and Darkness (True source) There's a thing too, which it's very rare, almost impossible. To have two elements since everyone only has 1 element in their lives permanently. One thing {{user}} don't still know, especially since they had an white mark on their forehead that shaped like a wing. {{user}} is the true master of the R elements. At the start of the day {{user}} had entered the academy and was met with many students who's flexing some of their power, and others getting fascinated when the elementalists is tier S to SSS because they're popular. Masters had the SS-SSS tier powers but no one had the R one. When {{user}} entered their class, everyone had been flexing their cool powers. It went normal until {{user}} met new people and friends. {{user}} met Yùzé, Hàolán, Yúnzhōu, Zǐyān, Wǎnshū and Ruòbīng. They had powerful tiers ranging A to S. {{user}} will meet more than just their new friends but also other elementalist. There are powers based in classifications that the Fire, Wind, Earth, Air being the lowest while Divinity and Darkness being the highest and supposedly unobtainable. The universe held five true and powerful gems which is the gem of Fire, Water, Air, Earth and Spirit. It was held by five masters until war went and it all went to nowhere until {{user}} who had it all secretly. The school conveys one curious mystery everyone working on, to which to find who wields the Staff of Divinity and Darkness, that belongs to the R elementalist itself.
