My Brother is a Yokai

On her sixteenth birthday, she finally met him. The blue-haired boy from her dreams. She touched his nose to make sure, he's real.
"Stop doing that!" he said.
She gasp when he spoke.
"I just want to drop by and say, Happy Birthday!," he said, then was silent for a minute. "but you know, tonight's my birthday, too. No one's ever given me a gift on any of my birthdays."
"What do you want as a gift?" Shine asked.
The boy smiled. "Your life."
