About this game
Prequel: The previous title is Shining Immortal, but you can fully enjoy this game without playing it.
Story
This is a world where science fiction and magic coexist.
The story unfolds from the perspective of the male protagonist. After meeting a mysterious online acquaintance, he is drawn into a dangerous journey in search of “love.”
Background
Long ago, the God of Matter descended into the mortal world through a tree.
It bestowed divine power upon all living beings, demanding in return their faith and reverence.
Yet humanity was not content to simply look up in awe.
They sought to touch, to unravel, even to command the divine—
until, at last, they provoked its wrath.
And so, disaster fell.
People fled to the mountain, where deep within its heart, they built a “Shelter.”
Gameplay
The game combines 80% visual novel storytelling with 20% mini-games.
Progress through the story by reading while engaging with interactive gameplay.
A small number of branching choices that influence the protagonist’s actions
Reconstruct memories, evade enemies, explore maps, and interact through point-and-click mechanics
Occasional failures may lead to alternative outcomes
