It is not a type of anime that a world should know.....as it don't contains any action or adventure....but It is a gift of a profound friendship...and these types of anime is really needed for progress of humanity.....yes this a kind of anime that made me cry whenever I give it a run.....so i satisfied with the part wise rating of IMDb but the overall rating(8.4) is not enough....it should be(8.7)....thanks for spending time to read my comment...
