Adapted from a manga published in late 2017. Plot Summary

While the world slumbers, the sunflower, now bathed in lunar luminescence, undergoes a metamorphosis. Its stature, once imposing and sun-kissed, softens, and its beauty becomes more introspective. The moon's gentle beams coax the sunflower to surrender its diurnal radiance, allowing its delicate, almost ethereal, nature to emerge.

"Sunflowers Bloom in the Evening: A Symbol of Hope and Resilience"

The phrase roughly translated to "The sunflower blooms at night, surpassing the sunflower's peak," and it held the key to unlocking the secrets of the mystical flower. According to legend, Himawari's nocturnal blooming was not just a quirk of nature but a sign of her elevated status among the sunflower hierarchy.

The concept of a sunflower blooming at night ('Yoru ni Saku') taps into a romanticized ideal of nature's mysteries. It evokes images of moonlit gardens, where the typical day-blooming flowers have closed up, and the 'Himawari' takes center stage. This nocturnal blooming could be an adaptation to attract night pollinators or simply a genetic trait that adds to its ornamental appeal.
