Anime Crossover: Post-Apocalyptic Survival, My Stand is the World

When Su Chen woke up, he found himself transported to a peaceful world made up of countless slice-of-life anime.
My classmate is Yukino Yukinoshita, the school next door has Utaha Kasumigaoka, and even the national idol on TV is Mai Sakurajima.
Just when he thought he was about to embark on a fantastical campus harem adventure—
The Silent Catastrophe has descended, the world has fallen, and monsters roam freely!
At the crucial moment, Su Chen bound to the [Infinite Stand User] panel, awakened the Stand [World] at the start, and internally cultivated the supreme technique [Triple Rebirth]!
When the once-proud young women trembled and fell into despair in the apocalypse.
Su Chen went against the flow, strolling leisurely amidst the vast army.
"ザ?ワールド! 时よstopまれ!"
When time stands still, all beings are equal.
This is a story about a man who, in a post-apocalyptic world, protects all the beautiful girls with his invincible power and turns the entire world into his "paradise."
