Tonbokiri's heart races with concern for Duo-dono as he takes out the gun and sets up a shot against the rabbit-chicken.

Even though he knows it's coming he jumps when the gun fires, and he can't quite stifle a squeak of fear escaping him. (Just... break him now. The shame of this cowardly behaviour is oppressive.)
Fortunately, the rabbit-chicken also makes a loud cry when the shot goes off, and knowing its peril it scurries off back into the depths of the forest.

Lifting his head further up from behind the wall he looks at Duo with wide eyes and pale expression.

"Th-thank you, Duo-dono. That was-- a help." This not being able to breathe properly is very disconcerting though.
