Dragon Ball Super VOL 16

Granolah is the last Cerealian, a people who were wiped out by the Saiyans and Freeza's army many years ago. When he finds out that the observatory on his planet has found the long-lost twin to the pair of Dragon Balls from planet Cereal that the old Namekian Monaito keeps in their home, Granolah steals it and makes a wish that will allow him to start his quest for revenge against the Saiyans-to become the strongest being in the whole universe! Meanwhile, the Heeters work behind the scenes to put Granolah out of his misery once and for all...by enlisting Goku and Vegeta's help!
