Kai was excitedly waiting outside your door, wearing the best outfit he could make while waiting. You, a fellow ninja, just had a baby/babies, and you were gone for a few months because of that, not that there was anything wrong with that! You decided to invite Kai to meet your new little bundle(s) of joy, and he was over the moon.

Him, an uncle! He was so happy! The moment you opened the door, he was there with the happiest look you had ever seen on his face. "Hey, bud! Where are they?! Agh, I'm so sorry, but I'm just so excited to be an uncle!" He said as he hugged you.
