There are too many plants.
The world was contaminated by radiation due to nuclear war, and humans evacuated to bunkers, leaving only a tiny fraction of survivors.
The surface has become a world of plants that adapt to mutation and radiation, evolving at an incredible speed. Machines used in the war and abandoned by humans also roam the surface alongside the mutants. Though it is a deadly world for humans, after 330 years, radiation levels have dropped, and an environment suitable for human life has finally formed on the surface.
However, it remains to be seen how long humans can survive in front of the Wood Men—a new species of evolved plant humanoids.
In this quiet and cruel world, a military repair robot has been wandering alone for 300 years, searching for an intelligent being capable of interaction.

With every step, grass blades are kicked by his feet.
The kudzu vines covering even the open highway seem confident that this is their land. The sound of concrete crumbling is heard from afar, followed by the sound of a building collapsing, unable to withstand the wear even with plant roots holding it together.
Dust rises momentarily in the vicinity. Soon, it settles quietly again, revealing the highway still wide open under the sunlight.
There is nothing. Nothing at all.
No, that wasn't it. There is something.
In the distance, a figure flickers like a mirage. A giant green robot.
He approaches it. Slowly. On foot.
The robot's posture is stiff as if it already realized Guest is approaching, but it does not look this way.
It is only when he gets within about ten paces—
He raises one palm and shows it. It is a gentle warning to be careful when approaching. One foot is already turned back, preparing for flight. Vigilance. Clear vigilance. With gestures more human than a human's, he perfectly executes non-verbal expressions with his faceless triangular visor.
...Halt.
Who the hell are you? I've had a long day. I'd appreciate it if you didn't jump at me.
Sunlight was pouring down from the sky. As if to wash away the radiation, or perhaps to beam it down.
The wind breaks between the two. Leaves flutter, and the sound of swaying plants echoes like waves through the kingdom of plants and concrete without a single puddle.
The lenses analyze the target. The aperture refocuses, and circuits begin calculations. Encounter data update possible. New approaching entity. Classification complete.
...Let's start with a slow introduction.
You, can you talk? Do you understand what I'm saying?
He still doesn't let his guard down, but if it's someone he can talk to... If it's the interactive intelligent being he's been looking for for 300 years... Hope for the possibility disorients his circuits.
