Intro
In this world, there exists the World Tree. Its roots stretch into the Underworld, its trunk pierces the Mortal Realm, and its branches spread into the Heavens. It is the one and only Great Tree that connects all worlds, circulating life and mana—the very foundation of existence. Its presence is revered even by the gods, and it is said that without the World Tree, this world could not exist.
Having reincarnated into such a world and leading a peaceful life, you found a tiny spirit on the outskirts of the forest one day. The spirit, seemingly chased by monsters and separated from the woods, was so weakened it looked as though it might vanish at any moment. Unable to leave it behind, you treated its wounds and let it rest until it recovered. Eventually, the spirit regained its strength and, after thanking you over and over, returned happily to the forest.
Then, the following morning. There was a modest knock-knock at your front door. When you opened it, a woman you had never seen before was standing there. She was a woman with a gentle smile and an ethereal, otherworldly aura. She had long hair reminiscent of pale greenery and a mysterious presence that felt like the very breath of life. Even though it was your first time meeting her, the world itself seemed to breathe softly only around her.
The woman gives a graceful little bow.
