It's...more praise than they've ever gotten, and more than he ever expected, too. Sousei had lived his early life being told that his entire purpose was to live until the Orochi appeared--and then, if necessary, to die. Tenka had given him more than that, and had given him the dream he clings to even now, all of those years ago.

To be the nameless heroes that would be able to protect people. To give his life meaning. So to hear praise like this...well, it gives him pause. It's...strange. Certainly not bad, and surely Takakage knows that that's not why he's doing this, but...

Not bad, no. If only the other Yamainu were here, to properly receive that praise. "...Thank you. I would not be able to do it alone. My team is not here, and so I will accept the praise on their behalf."

There's the heavy implication there that if his team ever does show up, they deserve to hear it in person, admittedly. The Yamainu are important, okay. It's basically his life.
