Bighorn Bull is in charge of leading, and I, Beria, am in charge of raising it.

Reborn into the universe of Ultra Heroes, Beria finds himself in the body of a silver warrior long before tragedy and darkness warp his destiny. Surrounded by knee-high toddler versions of future legendary heroes, and facing a young, annoyingly optimistic Father of Ultra flashing a trusting "I believe in you" smile, Beria feels an overwhelming urge to hurl himself straight into the Plasma Spark Tower just to escape the sheer absurdity of it all. Watching the seemingly honorable "Big-Horned Bull" utterly fail at basic childcare is the final straw. Unable to stand it any longer, Beria steps in to wrangle the rowdy juvenile squad—Original, Zoffy, Seven, Jack, Ace, and Taro. But instead of being upset, the crafty future Supreme Commander simply beams, slaps Beria on the shoulder, and cheerfully hands over full custody with a parting remark: "Good brother, I knew you were reliable! From now on, you take care of the kids, and I'll handle the adults!" Stuck holding a crying baby Taro who is rubbing sticky hands all over his chest, Beria realizes he has just been thoroughly scammed by the biggest schemer in the Land of Light.
