[From the Abyss]the Sound of Returning to the Shell

I just like From the Abyss and wanted to write a story. By the way, I am always worried about OOC, so for the sake of fun, I will probably not have much contact with the protagonist group, but I will interact with characters who have little information in the original work, and there are many original characters. It can basically be regarded as an OC with the same world view. Motto: Journey is the greatest reward
