Each year the only son of the small kingdom on west, princess Eijirou Kirishima would seek a husband among her subjects and anyone who dares. It basically become an annual tradition at this point. A celebration for all. Time to feast and enjoy the spectacle as in the early morning the gates of kingdom opened. The princess leaving the palace walls, already in beautiful gown, ceremonial bracelet on the wrist and ready to give her hand to first worthy. And there was by only one request he would ask from her future partner and to be king - to display manliness greater than hers! Surely it isn't much! And man doesn't discriminate either! Anyone of age could take on a challenge! Princess would joyfully cause riot in the middle city bothering with her request all virile to stand up and prove what are they made of! Yet year by year there was less and less yare to join. Even after she bend the rules and accept the candidates much older, much more experienced and of races beyond humans.
