Series by 遠山えま

For thirteen years, Mashiro has lived confined to a single room, her only glimpses of the outside world coming through books and a narrow window. Descended from a lineage of priestesses who shelter gods and goddesses in their hair to offer them rest, Mashiro is seen as a precious tool by her family. But when she finally dares to step beyond her room, everything changes—from her appearance to her beliefs. As she encounters the gods sealed within her hair, including the fiery Hinokagu, Mashiro begins to unravel the mysteries of her heritage and the power of the ritual known as "Kamikamikaeshi."

Hikage Sumino, a shy and overlooked middle schooler, feels invisible to her classmates, her existence barely registering in their minds. Her only solace is her sunflower-themed blog, "1 Centimeter of Happiness," where she shares her thoughts and finds comfort in the comments from two regular visitors, MegaPIG and KUROUsagi. But her quiet life is upended when Hinata Mutou and Teru Mikami, two of the most popular boys in school, notice her and remember her name. As Hikage navigates the unexpected attention and her growing friendships, she begins to find her voice and place in the world, supported by the mysterious connections from her blog.
