蛍火の杜 (Hotarubi no Mori e) (Blu-ray release 2012-2-22) is an anime adaptation of a manga short story. In this story a 6-year old girl got lost in the forest, then met a human-looking spirit, who must not be touched by human otherwise he will vanish from this world. Many years later their friendship grew into a romance. Their love story is tender, simple and beautiful. The animation is great. No wonder many people love it. Although I understand the ending is inevitable from the story, I do not prefer it.
