The Daily Life of the Substitute Messenger in the Comic World

(Stand-in messenger + fusion of multiple anime world views) My name is Qiao Jiu, and my English name is Qiao Nai Joestar. I am a time traveler and a substitute messenger. My substitute is Platinum Star. I traveled to a comic book world. My grandfather is Joseph Joestar. He always likes to call me JoJo. During a mission to clean up Italian gangsters, my grandfather suddenly arranged for me to go to high school in Neon. Ever since, I will enter Neon and become an ordinary high school student. Well, it's not that ordinary in daily life.
