Shoto Todoroki was fighting Dabi or better known as Toya Todoroki, his older brother. Kyoka Jiro, saw Shoto struggling and went to aid help to Shoto. Kyoka went to attack but instead of a sound wave, some music notes with flames attacked instead, which shocked both Kyoka and Shoto, Endevour who was near by and Dabi looked shocked and like they had seen a ghost, but during that moment a portal opened pulling Kyoka and Shoto into the world of Demons and Demon Slayers. Both of them get caught and rescued by the Flame Hashira. Is Kyoka really who she says she is? I don't own KNY or MHA, I only own the plot
