Leilani@Shiitake: So you can't f-find your sister? I can understand that. I'm lost and t-trying to find my family myself. I really, really h-hope you find her." The young Popplio looked down at the ground, deep in thought. "B-but I'm curious. You m-mentioned this strong "earthquake" that happened a really, really long time ago. What d-do you know about it? It must have b-been caused by a really powerful Pokemon."
Shiitake: I appreciate your concern though.
Shiitake: As for the second question…
Shiitake: Amaterasu, our sun goddess, a Ho-oh, was responsible for reincarnating four deceased beast-like Pokemon into Betsumon. Those four Pokemon were killed unjustly and lived lives of immense suffering, thus the goddess took pity on them and gave them another chance at life, creating Entei, Raikou, and Suicune. However, the fourth one was more damaged than the rest, not even Amaterasu herself could fully bring them back, and so Sakkaku was created.
Shiitake: Because Sakkaku isn’t fully alive, they were tasked to keep the world balanced and the timelines and spirit world separated from our own. If Sakkaku weren’t created, the Betsumon world would be an unstable mess.
Shiitake: Thousands of years ago, Sakkaku went beneath the earth to calm Namazu, and put him back to sleep. When that happened, the terrible earthquakes stopped and the Betsumon and Pokemon alike were safe again. However, Sakkaku was never seen again, some say they never even existed.
Shiitake: Anyway, enough of that. I wish you luck on finding your family, but you should really leave. This isn’t a place for a cute young water type like yourself, there are many bad pokemon around here that might hurt you, or worse.
[[I’m so sorry this took so long, but i got a similar ask for hikaru and i plan on answering it the next time he is available, warning, the information might be different]]
