Riku's eyes widened a little in interest as Teito formed the symbols in the air. He gently reached out towards it, but stopped short of actually touching the runes as common caution halted curiosity.

"That's actually a pretty good idea. Are the symbols letters, syllables or words? If they correspond to our letters someone might be able to crack them, which means we might want to write with code words or write our lines backwards. Something."

He folded his arms. "Either way. It could mean we could now send letters in the mail, or even take snapshots of the text and post it publicly, if we think we could get away with it. And yeah, it probably would be best if you taught it. We don't want too many translator pages around in case the Organization finds one."
