Siblings

Selena blinked, caught entirely off guard by the sudden hostility between the two creatures. "Wait, hold on. Are you two... Siblings?"

"Unfortunately," Heihei hissed, its golden eyes narrowed.

"Unfortunately for me," the raven shot back. "Do you know how insufferable it is to be related to a creature that sleeps half the day and only wakes up to lick itself clean?"

"Better than being a loud, obnoxious pest who thinks flapping around and stealing shiny objects counts as a personality!" Heihei retorted, leaping onto the desk to level itself with the raven.

Selena stared at them, her head swivelling back and forth as if she were watching a particularly bizarre tennis match. "You two can't be serious," she muttered under her breath.
