[Main Curse Returns to JOJO] My Substitute Cannot Be the Strongest Spellcaster

I have disliked my brother since I was a child. Although he has a gentle temperament and good looks and talents, he always gives me face when he comes to the parent-teacher conference every year. However, he lives like a plant, and his early thirties feel like he has entered his twilight years. Even his bright blond hair cannot make up for the old man's smell in his soul. He even said that he just wanted to live a peaceful life... Humph, that's boring. What's the difference between a life that doesn't save the world and a dead fish? In order to practice and become a beautiful girl hero who saves the world, I do 100 push-ups, 100 sit-ups, 100 squats, and 10 kilometers of long-distance running every day - finally! When I was 15 years old! Got a super back spirit! Oh, my dung-headed bamboo horse told me that this is actually called a substitute. – In short, in order to better cooperate in the battle and strive to save the world one day, my stand-in and I gathered around a table of desserts and started talking. The white-haired stand-in with an eyepatch on his face told me: He is not a substitute, he is the most powerful magician. I watched him eating dessert with such an embarrassing look that there was crumbs on the corners of his mouth, and I said with great disdain: If you are the strongest spellcaster, then my living dead brother is a perverted murderer. – A few months later, I met a spellcaster in my class to try to find out whether I was related to him. Intention: to destroy relatives in a righteous way.
