"The whole situation is caused by two demons, being the Demon King Dabura and his little sister Towa, along with Towa's creation Mira," Chronoa said, "they've been plotting to revive the Demon Realm using energy they are gathering from these changes in the timeline, or to empower themselves while doing so."
"I thought Dabura fell under the influence of Babidi and was killed when Majin Buu turned him into a large cookie and ate him?" Godel asked.
"That was his original demise, yes," Chronoa said, "but in once instance, Towa used her ways to alter history in order to save him."
