HINODE

Sunrise as end of the power of evil spirits

Hinode, the break of dawn, signals the end of the power of evil spirits over the waking world. The holy light of the sun banishes yōkai, ghosts and demons back to the places from which they came.

Throughout all anime, it's common that sunrise happens when the main conflicts and battles are over. Its appareance is similar to the natural phenomenon, without particular change. That's why it's hard to say if the content is explicit.
