Not a Pillar, but a Railgun

Misaka Makoto, the Electric Prince of Tokiwadai's prestigious boys' school, transmigrates to the ghost-haunted Taisho era after resolving the issue of 20,000 Misaka little brothers. Perhaps something went wrong during the transmigration, because he lost his memory. To get it back, Misaka Makoto sets out on the journey to find Tokiwadai again, with 12 arcade tokens in his pocket. "No, why is your sword electrified?" "The lightning behind you... Am I seeing things?" "Are you a student of Thunder Breathing too?" "Who the hell attacks with arcade tokens?!" Misaka Makoto: "...?" Do you people discriminate against superpowers? * After regaining his memories, Misaka Makoto, Academy City's third-ranked Level 5, one of the most powerful among a million people, firmly believes that there's nothing a single Railgun can't solve. And if one doesn't work, fire two. "What's the big deal?" The cheerful boy with short brown hair tossed an arcade token into the air. "Bilibili!" A mushroom cloud shot into the sky. Demons: "..." Kibutsuji scum: "..." The Hashira: "..." Wait... Can you use superpowers to kill demons too??? P.S. Any OOC is my fault and has nothing to do with the original characters. Theme: Love and justice
