The translator I use got me the words for Ran's unlocking phrase, which are actually partial sentences. And actually, entire sentences aren't that hard, you just need a very VERY basic grasp of the language.
They're Subject Object Verb.
We're Subject Verb Object.
So
Subject - Verb - Object
I Eat Bread
Becomes
Subject - Object - Verb

As far as the rest of everything else for the battle system? That'll be finished when our Captain gets time.. you don't use a freeform system for now, since Arrancar haven't been finished yet, try a different system, and then go arrancar later.. or play another character, and make the arrancar later alltogether. There are some different options. You just have to be flexible enough to use them.
