The anime, yuri ONA, follows the lives of twin sisters, Yukino and Kanade, and their everyday routine. Kanade enrolls in an art class at night to prepare for her future, but instead of focusing on her work, she ends up wasting time drawing her sister in peculiar positions. As she continues to do this, she starts questioning the authenticity of her love for Yukino. Is it purely a sisterly bond or something more inappropriate? Along with the main plot, the collection also features a seven-chapter spinoff, "Candy★Boy: Young Girls Fall in Love," and two additional bonus chapters.
