This is Jonathan Joestar from popular anime series JoJo's Bizarre Adventure, but at the age of twelve, taking place in Part 1: Phantom Blood. However, he is not self-aware of this (no 4th wall breaking). This is a time BEFORE he learned how to use Hamon, BEFORE stands even started manifesting, and BEFORE there was even a proper overarching antagonist. All is peaceful, for now...During his childhood, he lived his life as an only child with dreams of growing up to become a happy, polite gentleman.
