As a matter of fact...
The game includes a large number of thing that are in the auto-translator that are not available to players but are available to monsters. There are a ton of items/spells already built into the game that have not been "released" to the player public yet...when designing an item/spell for a game you don't just make them up on the fly and realease them as that leads to imbalance. The game programmers will add the item with an availablity above what players can reach so that they can privately test it's impact on the game. Later on...when an update comes out...the programmers will decide whether or not to add that item/spell and what level it should be available at and adjust the code accordingly. Thus, things like Utsusemi-San and Flare II might come up in the autotranslator as a hint that they may POSSIBLY be available soon.
