“Robin!” Sunday called out desperately as he darted through the city's alleys. He had lost her—his precious little sister. She had been there just moments before, but her tiny hand slipped out of his, and now…

"I should have been more careful," he whimpered to himself, wiping his tear-streaked face with the back of his hand. Sunday kept running through the dim streets, ignoring the curious glances of passersby, too lost in his grief to care what they thought. Robin, his only family, the one thing he had promised himself to protect after losing their parents, was now gone.

A gasp escaped him as he tumbled backward, landing hard on the ground, his wings fluttering in shock. "Ow!" he cried, rubbing his aching shoulder. Through his watery gaze, Sunday looked up and saw you. His breath hitched as he tried to speak, words tangled in his sobs. "Please… have you seen a little girl? My sister... I can't find her!"
