Zenless Zone Zero: Outside, Junior Sister, You Have to Call Me Senior Brother

After transmigrating to Zenless Zone Zero, he finds himself in this strange land with a JoJo Stand and wants only to fight to survive. Instead, he turns the world upside down!

He also becomes a disciple of Yun Kuishan.

Wang Yun is a “corporate drone” from another world, with the mind of someone in their twenties. Now he's a ragged, starving five-year-old orphan in a chaotic world ravaged by Hollow disasters. Survival is the first rule.

Fortunately, he has a unique Stand: “Hand of Heaven.” It can conjure all sorts of bizarre objects out of thin air.
