Actual information?

I've been looking around at the other wiki pages this references, and can't find any real information anywhere. Where does it actually come from? I've heard the Hamlet Delegation Event was the only place it was obtained from, however it references the Christmas Gachapon. The sword is not listed as an obtainable item on either of those two pages. Also, why is this listed as a Blacksmithed Item? It obviously can't be made via blacksmithing unless there's a manual somewhere I haven't heard of. I'd fix the page, but I honestly don't know the correct information. It needs to be done though.
