Why I go for this manga ? Because there are not only it shows about the legend of historical. It also teach us about consistent, independent..... On top of that, the manga highlights about the love between every people which made the succeed of this manga. What's more, when I read this manga, I felt very funny because of some pages of story couple with the feel to be moved to tears because of their love which they gave another people
