For all that it's a little weird to be bowed to as a shinki, it's totally Hakkai-san.

Yukine peers curiously at the dragon when Hakkai starts whispering in his ear, worry creeping up on him. It'd all be for nothing if Jeep doesn't agree--

But whatever Hakkai-san said convinced him, and he sighs slightly in relief. Hurrying over to the driver's side with a smile he nods his thanks to Hakkai as he climbs in.

"Thanks, Jeep! I promise I'll be careful!"

To that end he instinctively searches for a seatbelt. All vehicles should have them, right? ... Except maybe dragons-turned-jeep?

"Uh, Hakkai-san, isn't there a seatbelt?"
