Fuka Watanabe is the head of the Gardening Club. Although she does not stand out in class, she is a kind-hearted girl with a charming smile. "I like you, Watanabe-san!" "Actually, I like you, too…" And so, the high school boy Gyoto Ohki's first confession is successful… like a dream come true. But just as his first love was about to be fulfilled, her appearance changes completely. Now she looks just like an elf! "Could it be… that you can see…" It turns out that Fuka Watanabe really is an elf....... She is a Sun Elf who has come from the other world of “Natchez Revilla” to modern-day Tokyo, in order to escape a certain curse. "The truth is that, I too...... have always been interested in Ooki-kun. Your name, Yukuto, it kind of reminds me of Yggdrasil!" "Can I get a do-over on the confession!” Watanabe the elf, and Ohki the boy, are caught up in a grand adventure set in a fantastical modern Japan, with the fate of two worlds at stake.
