Hoshikuzu no Koe

The world has been laid to waste. The only place that's able to preserve its prosperity, is a village protected by the charm of the "star deity". Every few decades, there comes a moment where the "star deity" changes its vessel for another. Those eligible to house said "star deity" are children born with star-shaped pupils – they're called "star children". Protagonist Yoru and deuteragonist Akari are two of these "star children." They head to the sacred grounds together where the inheritance ceremony, to become the vessel of the next generation's "star deity," is held. In preparation for the event, they first have to spend three days inside of the star deity's residence? Among the "Star Deity", the village and Akari. In those three days Yoru has to choose what is the most precious to him. [Translated from the Official website]
