[Whining time over, Yato rejoins the group in time to interrupt any potential introduction by the other man for a moment.] Whoa, that's no good. Here, I [the benevolent Yato-sama-senpai] will help you out with that!

[With a suitable flourish Yato produces a regular PET bottle full of water. (Yep, be amazed!)]

[Yukine blinks in surprise then nods.]

You were actually prepared. Yah, let's use that now.
