Grand Priest- "As you wish.. In the Tournament of Power, when the Universes were wished back.. It brought back all of the 12 universes.. including the 6 that were erased by the Omni Kings himself.."
Goku- "What's wrong with that? Weren't those universes erased because they were weak?"
Grand Priest- "Yes, the universes were weak.. But it's what leaded them that isn't. Someone even stronger than me, lays dormant inside of universe 13.. My sister, Marcinnete.."
Yamcha- "Wait? You guys have names?!"
Hiyoki- "Yes, of course.. I am the Grand Priest, but I still have a name.. It's Hiyoki.."
Gohan- "So how are we supposed to beat Marcinnete? She's stronger than you! And you're supposed to be the strongest fighter in the universe.."
Hiyoki- "I'm going to train you, for I am an angel.. Angels can't surpase their birth strength.. Even with thousands of years of training..."

Hiyoki- "Then Let's begin.."
