Synopsis: Super Dragon Ball Heroes: Dark Demon Realm Mission!

Following his victory over Cell in his own timeline, Xeno Trunks teams up with Chronoa as a Time Patroller to take on the Time Breakers. The Time Breakers, also known as the Dark Empire Forces from the Demon Realm, have revived their leader Mechikabura with the aim of obtaining the scattered Dark Dragon Balls. These nefarious orbs have fused with old foes, endowing them with incredible powers, and Mechikabura seeks them out to regain his youthfulness. To foil the Dark Empire's plot, Xeno Trunks, alongside Xeno Goku and Xeno Vegeta, must step in.
