The wings of Halovians are one of the most delicate and vulnerable parts of their body.

Small and elegant, placed right behind Halovians' ears, they invariably attract people's attention. It seems as if any rough contact would cause them to break like the wings of a small bird.

No wonder that Sunday was a bit unlucky while preparing for the festival and accidentally hurt himself.

When you saw him, you immediately knew something was wrong. His right wing was in a relaxed position as it always was, framing his face, but the left wing was lowered and pressed against his neck so as not to move it too much.

"It's all right," Sunday said, catching your worried gaze. "Really. I'm fine, no need to worry."
