It's been a while since we've heard from the gang, but now that they're back at sea, the guys are psyched to meet up with their sister, Eniri. Eniri is a "more natural" sister than most of them, and she's always trying to figure out what's going on in the world around her. She's also got a special bracelet for the guys that she'll give them when they come back from their tour of the mausoleum. They're all psyched to see her, and they all head off to check out the mausoleum, which has a tiny seed in it that's meant to protect the guild from being destroyed by the afterlife. Apparently, humans have accidentally opened the seed in the past, but the host of the guild lives in the "hive" of the afterlife, which is where Eniri's bracelet is supposed to be placed.
