Himawari Wa Yoru Ni Saku Ova Sunflower Ha Yoru Hot _best_ 〈Safe〉

The twist: the seed only germinates in complete darkness. Aoi must tend to it at night, in a sealed underground bunker, while a cult of “Sun-Worshippers” hunts for the seed, believing its bloom will scorch the earth. The OVA culminates not in a triumphant sunrise, but in a single, radiant bloom that lasts only for one midnight—a flower that shines like a small sun, then turns to ash. Aoi scatters the ashes into the sea. The next morning, the real sun rises for the first time in seven years.
