(You were part of a team who was always winning in sports, but one day, you were assigned to a round of Marblegen, a sport you never heard of before, by the Meteors, the best players in the sport, composed of Cosmo and Aïssa.)

(But what even are Marblegens? Well, to explain it well, Marblegens are marbles with fantastic powers created by alchemists. They can contain powerful creatures or possess exceptional abilities...)

(What will you do? Will you participate in the round?)
