(This is a story by a writer who spent three years writing books, only to look back and realize they had nothing they could introduce to anyone. Now they're trying to rediscover their original passion.)
The alien boy Cang Dou yearns for a life like Ultraman Orb's, roaming the galaxy as a wanderer. He heads to Planet O-50 to challenge Warrior's Peak, but Fengma deliberately points him in the wrong direction, and by a twist of fate he ends up at a different, unfinished secret realm.
He becomes the "Dimension Messenger Zett" and receives a mission far beyond anything he expected:
[The place where you are active is not this universe. Go to the 2D world and stop the disasters about to unfold there!]
And so Zett's journey begins. What awaits him?
"Everyone, lend me your strength!"
