The HoClaus... Revealed!
To get the HoClaus, you need to find 3 Ninja-mas Ornaments. They're a not-really-rare drop from a D-Rank mission that shows up during the Christmas season. Three Ninja-Mas Ornaments allows you to complete a special mission (only one to open it) that is extremely easy (turn over the ornaments, get HoClaus).
Ren wrote this kind of thing down. I'll get the details from him for specifics.
