The Law of the Awakening Chamber

Ueki tells the rest of Robert's Ten (except Robert himself) that he defeated Aleggio. As a result, the Ten's Don decides to fight Ueki. Using his power to change his finger ring into a rocket, Don soundly defeats Ueki. In order to get stronger, Tenka has Ueki train in the Awakening Organ so that Ueki can raise his Heavenly-Being rank.
