Stop! Hammer Time (The Hammer is my Penis)

When I was four, I found out my Quirk wouldn't come in until I was older. When I was twelve, it finally came in. Now I need to prove I can be a hero when my power is literally taken from bad Hentai and is perfect for being a Villain. The Shinigami that handled my Isekai Paperwork to send me here must be laughing their ass off. At least Mei believes in me.
