Weeds with an Extra Tool by My Side

After arriving in another world, she becomes a blade of grass growing in front of a big shot's gate, and gets stepped on whenever nothing is going on.

The system activates, and a cheat ability is attached.

She's going to tell this big shot that one should have manners, and grass is not something you can just step on carelessly.

PS: The title and synopsis are plain and unremarkable; the author has already given up on this one.
