Is Sea Spirit'S Den Postgame In Pokemon Y?

When the tsunami came, ninety-five percent of the world's land disappeared beneath the ocean. I was just an ordinary graduate student in aquaculture when I was swept into the deep sea and unexpectedly awakened a god-tier talent: Dragon Lord. From then on, I could sense the emotions of marine life, issue simple commands, and even make elite sea beasts bow their heads and obey. While everyone else fought for a single mouthful of fresh water, I opened a ranch in the deep sea. With an army of sea beasts, I built a city of trade upon the sea!

Queen Asteria, the first siren has always hated the humans after what happened to her 5,000 years ago. But now her hate is also directed at the shifters she once called family. Asteria was betrayed by those she held dear, captured by the humans and forced to make a deal all to save the shifters from extinction. Will Asteria’s need for revenge cost her everything? Will she give in to her mate-bond with the last descendant of the royal Lycan Bloodline? Or will she be forced to live a life she despised? For the seas are soulless and so is she.

Floods, tsunamis, heatwaves, acid rain, deep freeze, earthquakes… In her last life, Sophie Zurer survived a grueling eight years after the apocalypse, only for her parents to die tragically while her brother melted in the acid rain. Born again, she avenged her parents, and with a void pocket in hand, she began to stockpile everything from weapons to food, agricultural manuals, and medicine… Eight years later, the city was once again torn apart by earthquakes while the oceans devoured the continents. However, while Sophie survived with her family, the apocalypse cranked up in difficulty as if it were a video game! This time, there were erupting volcanoes, undersea volcanoes, lightning storms, scalding seas, and fireballs falling from the skies… The apocalypse of the land was just the prelude to the apocalypse of the deep sea! Where would humans live when the last island was consumed by the sea?

I was a mermaid from the deep sea. Out of curiosity and playfulness, I was caught by a fisherman and endured unbearable torment. Just when I was on the brink of death, Trevon Chapman happened to pass by and saved me. So, I gave up my identity as a mermaid princess, left the ocean behind, and followed him into the human world. For five years after our marriage, Trevon granted my every wish and showered me with affection. I truly believed I had found a safe harbor I could depend on for the rest of my life—until fate struck with its cruelest blow. Trevon's childhood sweetheart had fallen gravely ill, and only a mermaid’s tail could save her. I begged him desperately, but he responded with chilling indifference. "You're only losing your legs. Corinne is losing her life. Are you really that heartless? You're just going to watch her die?" "Besides, you can’t return to the sea anymore. That tail means nothing to you now. From now on, I’ll be your legs." After the surgery, I sat in a wheelchair, running my hand over the empty fabric where my legs should have been, and calmly demanded a divorce. Trevon pulled Corinne into his arms, sneering. "You're neither human nor fish now—a monster. Without me, the only road left for you is death." Yet in the end, when I transformed back into a mermaid and leapt into the sea, his cries and desperate sobs echoed across the waves.

She was lost, nowhere to be found. So, he began to find her. Little did he know she was just there all along hiding beneath the sea.(This story involves Philippine Mythology, but I altered some things for the plot to work out, thanks!)
