Invertia was a meteor storm that caused an unprecedented disaster during the 20th century. Because of this disaster, numerous cities around the world were destroyed. However, within the meteor, an unknown element called mana was discovered. It allowed human technology to make rapid strides giving rise to a new species of super-powered humans, the Star Pulse Generation (Genestella). The Festas (Star Warrior Festivals) host battles between Genestella at a city of six academies called “Rikka,” also commonly known as “Asterisk.” Scholarship student Ayato Amagiri transferred into Seidōkan Academy in order to fulfill his own wish, swearing he too will fight in this city.
I just watched the first episode of the first season - I don't know what I think about it yet. It isn't too much special - kind of just makes me want to finish watching Hunter x Hunter for some reason; I think it's the whole idea of the competitions and battling in arenas and stuff that makes me think of the times they are trying to make money to get the game. I might keep watching it - but there is nothing extremely special about it IMO.
