The Thing Not Quite Sure What It Is (no ontology)
From Compile Worlds
The Thing Not Quite Sure What It Is is some kind of abomination that appears in Chibi Miku-san. It's a... errm... creepy cat thing with a drill-for-a-horn? The name's quite accurate, isn't it?
Despite the fact that no one is quite sure what it is, the TNQSWIS ended up becoming the jackpot (Alongside Capybara-san) once. I dunno why, but it just happened. Poor Rin ended up with the thing, and is understandably unhappy.
