Cherry Blossom Colored Blizzard

Please give me a “seed”! --The season is spring. After she failed her university entrance exam, the girl appeared in front of me along with Sakura Fubuki. She calls herself a Yuki-onna, and says she was given a role due to the danger of extinction of her species. Her role is to marry a lord and conceive a child!? A romantic comedy about an innocent, virginal Yuki-onna and a virgin Ronin who beg for a child!!
