A Certain Stand User's Kamijou Touma

Kamijou Touma is still Kamijou Touma. But before entering Academy City, he accidentally wandered into a place called Araki Manor, where he met a group of very interesting older guys. He learned a lot from them and became a Stand user.

Years later:

Misaka Mikoto: "How exactly did you meet my mom?"

Shokuhou Misaki: "I'd rather know how you met Kamijou."

Kamijou Touma: "My heart and my actions are as pure as a mirror. Everything I do is justice."
