[Demon Slayer] The Only One Without Memories

Natsuki Subaru has no memories, but he can read the memories of the dead. He has a vague sense that to regain his memories, he must kill someone. "He seems like a very gentle person." "Yeah." "He's a swordsman." "Yeah." "He's the strongest swordsman in history." "Yeah." "..." Out of the blue, he asked, "Have you had dinner?" "Yeah." After a pause, the strongest swordsman, Yoriichi Tsugikuni, hesitantly changed his answer. "I don't think I have...?" Natsuki Subaru: "Which one of us has amnesia, you or me?!" Later, Natsuki Subaru discovered that the Demon King Muzan could read the thoughts and memories of every demon under his command. Then he got it! This was like a supermarket sale where you got a whole bunch free with every purchase! The white-haired, heterochromatic-eyed boy looked at the most terrifying demon king in the world, excitement bordering on madness in his voice. "So, to put it simply, if I kill you, I can get my memories back, right?" ※ Re:Zero-style friendship between men. ※ This is Subaru from the Gluttony IF route, and he's rather fixated on his memories. ※ In short, Muzan has to die. ※ The title and blurb may change later. ※ I like characters who make snarky remarks! His personality will probably be a little more lively! This is a happy ending! Theme: The self and the true self
