At the end with Andromeda, we chose the [Unique Skill: Sky Walk] and the [Divine Holy Metal Creation]. I wasn't quite sure about the Sky Walk thing though, it was a rather weak Unique Skill I had copied from those powerful mecha androids that had showed up out of nowhere that one time, obeying Greenwood. They were part of some sort of prototype he was creating, they were robots that used powerful Unique Skills.
Yeah, now that I refresh my memory, it happened right after I defeated the Deep One, there was an invasion of Chaotic Beings that my daughter was stopping with my family, and Greenwood sent this trio there. Back then my daughters weren't as strong yet, so they were getting beaten really badly.
Luckily I got there in time… It was at that time I learned I could gain Unique Skills from foes I ate that possessed them, it was freaky though, learning that the things I ate could have been victims brainwashed and turned into those mechanical monsters.
