A jaded, reverse-isekai TS girl guides her former male self.
Oscar, the hero, had failed time and again in his quest to defeat the Demon King, each time returning to the past to try once more. No matter how strong he became, he could never overcome the Demon King, and his heart grew shackled by guilt over the lives lost.
But one day, upon returning to the past—Oscar the hero found himself transformed into a delicate girl.
Even if his form had changed, his desire to slay the Demon King remained. This brooding, former-hero-turned-TS-girl joins the hero’s party to battle monsters. Fighting alongside her are her former comrades—and her inexperienced, first-life self.
Haunted by the past, the ex-heroine fights on desperately.
