Ah okay, I just saw the part. For those of you who don't want to go back, Jii said,
"Now that Doukoku knows, the real battle starts here. Our lives depend on this secret plan. Please watch over us till the end."
Now, normally I'd say the secret plan is the sealing character, but if Doukoku knows about it he wouldn't really call it secret anymore, right? So he looks at the samurai armor to the left of where Takeru normally sits while he says that. Is he talking to our real ShinkenRed here meaning she's only supposed to show up in absolutely extreme situations, or just talking to God?
Also, this brings up another point. Does this mean Takeru can't use the sealing character after all?
