From Manga Garden:
Kotoko finds a strange wounded boy who collapsed on the ground. She saves him and asks only in return for him to celebrate her birthday with her. She lives alone because her father had passed away, but how can she still smile? And what is so unnatural in this boy she saved? It appears he can see more than human beings. What what will happen to him? Will he be saved? And will he agree to spend the day with her or stay as stray and lonely as he’s been from the day he was born…?
