Records of the Ups and Downs of Sea Waves

My name is Takeo Hayama, a samurai from Hirado, Japan, and a retainer of the Matsuura family. Three years ago, he was ordered to go to sea and disappeared in a shipwreck. Everyone thought I was dead. Three years later, I crawled back from the dead in Ming Dynasty, only to find that someone had replaced my life - a man who looked exactly like me, with my name, my clothes, my fiancée Abu on his arm, and became a guest of the Matsuura family. He said to me: "Come back? It's late." I am the fifth generation grandson of Emperor Jianwen of the Ming Dynasty, and I have royal blood flowing in my veins. But I also grew up in Japan as a samurai, with the moonlight of Hirado engraved on my blade. Now, I stand in the alley of my home, but I have become a person without a name. I want to take back everything that belongs to me. Not by begging, not by waiting - but by the knife in my hand, and the secret that even the impostor doesn't know. From the waves in Hirado to the beacon fire in Taizhou, from the battle flag of Qi Jiajun to the secret scroll of Emperor Jianwen. Who I am? Where do I belong? I'll find out when I cut it all open.
