Saitama: I Am a Hero Driven by Interest

My name is Saitama. I was originally an ordinary student, but I was killed in an incident where I was trying to save someone. I thought this was my destiny, but I didn't expect that not only did I not die in this incident, but I accidentally traveled to the One Punch World and merged with Saitama's soul, becoming a brand new teacher Saitama. Well... Since I became Saitama, I will inherit your dreams and justice. Three years later—— Boom! ! "Ah! He's a weirdo!" "Help!" People who were still walking on the street were suddenly attacked by a terrifyingly powerful weirdo. "Hahaha, I am the watermelon weirdo who accidentally turned into a weirdo because I ate too much watermelon!" A ghost-level weirdo with a long watermelon look on his face looked at the people who were running away and laughed coldly. "Eh? Who are you, the bald man? You didn't run away like those ants." But at this moment, he suddenly saw a bald man slowly walking towards him with an expressionless face, which instantly made him a little interested and confused. "Me? A hero driven by interest." The bald man responded expressionlessly.
