My Grandfather Came from Another World

He came with just one mission: to heal Earth.

From a "seed" capable of changing an ecosystem to a "fruit tree" that can strengthen the immune system.

From one person's farm, to balconies filled with the scent of fruit, and then to a world quietly transformed.

The alien grandfather Saga and his Earth family have no superpowers, only a gift sent across light-years and hands willing to sow seeds.

They believe that a truly perfect world begins on your windowsill, with a glowing fruit you grew yourself.

This is the gentlest kind of "civilization upgrade."
