Cypher/cipher for me.

As little as I know/care to know about the Japanese language, wouldn't Tidus indeed be pronounced /tee-dus/? Wasn't his name originally Tiida or something...? As far as I know i makes an 'ee' sound in Japanese so...Tee-dus is my guess, perhaps Tie-dus would be romanization?

Then again, this isn't about Tidus' name...

So yes, I say Cypher/cipher (s'far as I know those'd sound the same)
