Idea ahoy.
How about Kouryuu standing over a lab bench, where Tech has an exposed high-voltage circuit he was working on. Kouryuu should be leaning his nose in really close to the circuit looking curious. Tech, who had stepped away for a few minutes prior, should see the dragon and panic about what he's doing!
Feel free to add a second panel where Tech somehow ends up getting an electrical arc zapped through him, if you please.
